Uranus – Planet From The Sun Sample Essay

Uranus, the seventh planet from the Sun, has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. Despite being visible to the naked eye like the five classical planets, its dimness and slow orbit prevented ancient observers from recognizing it as a planet. However, it was eventually discovered in 1781 by Sir William Herschel, marking the first planet to be discovered in modern history. This discovery expanded the known boundaries of the Solar System for the first time in modern history (Encyclopedia: Uranus (planet)).

Uranus, the first planet discovered with a telescope, had previously been observed numerous times but was often mistaken for a star. On March 13, 1781, Sir William Herschel observed Uranus through his own reflecting telescope at his residence in Somerset, England. He initially identified it as a comet, but also acknowledged its resemblance to a planet. Following this discovery, Herschel alerted other astronomers who began observing Uranus as well (Uranus (2), 2009).

Upon observation, it was discovered that the object had no coma or tail. Its nearly circular orbit led scientists to conclude that it was a planet, not a comet. Initially, Herschel named the planet Georgium Sidus, which means George’s Star in honor of King George III. However, this name was not widely accepted outside of Britain, and alternative names were suggested. Some proposed naming it Herschel after its discoverer, while others favored the name Neptune.

Uranus, named after the Latinized version of the Greek god Ouranos, is our Solar System’s coldest planet with a surface temperature of around -224 degrees Celsius. Despite not being the farthest from the Sun, its frigid temperatures are due to its low internal temperature. This is evident in Uranus’ core temperature of 5000 degrees K, significantly lower than Jupiter’s core temperature of 30,000 degrees K.

Uranus, an ice giant, lacks a solid surface and instead has a layer of clouds known as its ‘surface’, situated above a potential layer of liquid water and rock core at the planet’s center. The composition of Uranus’ atmosphere consists of 83% hydrogen, 15% helium, and 2% methane, alongside trace amounts of other gases like ethane. In terms of size, Uranus is approximately 15 times larger than Earth, making it the third largest planet in our Solar System after Jupiter and Saturn. It is worth noting that the size of Uranus’ core alone matches that of our entire planet (Fountain, Observatory, 1999).

Uranus, with a mass of 8.68103 × 10^25 kilograms, is 14.54 times the mass of Earth. Despite its larger size, Uranus has a lower density compared to Earth, with Uranus having a density of 1.27 g/cm³ and Earth having a density of 5.52 g/cm³ (Encyclopedia: Uranus (planet)).

The average distance between Uranus and the Sun is approximately 3 billion km or 20 astronomical units (AU). It takes about 84 Earth years for Uranus to complete one revolution around the Sun, while it completes one full rotation in about17 hours and14 minutes (Uranus (2),2009).

Uranus has an axis tilt of98 degrees with respect to its orbital plane. This tilt causes alternating periods of lightness and darkness that last for approximately half of its orbit, which amounts to about42 years at each end because during half of its orbit one pole points almost directly towards the Sun while the other pole points towards the Sun during the second half (Encyclopedia: Uranus(planet)).

According to Fountain (2007), Uranus has 10 known rings and a minimum of 18 moons, although recent studies indicate there could be as many as 27. Due to its gaseous surface composition, volcanic activity is absent on Uranus. Nevertheless, certain moons of Uranus may possess ice-spewing volcanoes (Fountain, 1999). Contrary to previous belief in its monotonous climate, the Hubble Space Telescope has unveiled dynamic weather patterns on the planet (Colombo, 1998).

Despite receiving less energy from the Sun compared to Earth, Uranus still encounters intense wind storms, with wind speeds reaching up to 900 km/hr. One of these storms, known as the Great Dark Spot, is immense and covers approximately 13,000 km – equivalent to Earth’s diameter. With a magnitude of roughly 5.3, Uranus is visible to the naked eye in very dark conditions without any hindrances like clouds. It is the most distant planet that can be detected without telescopes but typically necessitates referring to a chart for locating it in the sky.

NASA launched the Voyager 2 probe in 1977. On January 24, 1986, the probe reached its closest distance to Uranus, getting as close as 81,500 kilometers to the planet’s cloudtops. Afterward, it continued its journey to Neptune. During its mission, Voyager 2 investigated various aspects of Uranus, such as its atmosphere’s structure and chemical composition. Additionally, it conducted the first comprehensive studies of Uranus’s five largest moons and discovered ten new moons. It also examined all nine known rings of Uranus and identified two previously unknown rings. Furthermore, Voyager 2 analyzed the planet’s magnetic field, including its irregular structure and tilt (Encyclopedia: Uranus (planet)).

This flyby is currently the only investigation conducted up close, and there are no current plans for other visits. Uranus is a fascinating planet. Despite our extensive knowledge about this celestial body, there are still many discoveries to be made. We hope that more probes will be sent to explore Uranus, which will help us understand its remarkable nature better. The solar system always holds new revelations, and situations like the accidental discovery of this planet make us wonder: what other mysterious entities might exist out there, patiently waiting for us?

Barbie Dolls And Bratz – Which Is More Progressive?

Ever since it was first introduced in 1959, the Barbie doll has gained immense popularity among children, especially girls, thanks to its prominent position in the toy industry. Throughout the years, Barbie has consistently sparked controversy and generated discussions, a trend that is expected to continue. The idea behind Barbie revolves around young girls imitating the doll and aspiring to be like her as they grow older. DuCille argues that toys and games are not just sources of entertainment but also play a crucial role in aiding children’s comprehension of their environment and shaping their values.

According to the author, dolls, specifically Barbie dolls, encourage children to imitate and envision themselves as these dolls (268). In terms of Barbie’s occupations, they have evolved considerably since the second wave feminism era and now include more progressive roles typically associated with men’s work. When compared to other toys for young girls and the jobs they portray, Barbie represents forward-thinking and innovative careers for young women. In contrast, Bratz dolls are less revolutionary compared to Barbie.

Despite Bratz dolls only having one occupation in their name, which is pop star, Barbie is considered more progressive when it comes to career options for young girls. However, without comparison to Bratz dolls, Barbie’s progressiveness may be questioned. Parents should consider allowing their children to play with a toy that, although progressive compared to Bratz dolls, may still have regressive qualities when not being compared to them.

This paper aims to evaluate the evolution of Barbie’s occupations from second wave feminism to third wave, as well as compare her progression to that of Bratz dolls. It also questions whether Barbie’s positive image remains intact when she is considered on her own, without comparison. Additionally, this paper will explore the placement of other toy options for girls within Toys “R” Us and analyze the role of parents in controlling their child’s play and interactions.

The Barbie doll line called “I can be” seeks to inspire young girls by using Barbie to imagine different career paths for themselves. When Barbie was first introduced in the 1960s, she was depicted as a fashion model, wearing an ensemble that highlighted her legs, arms, and upper body. This portrayal not only attracted photographers but also drew the attention of the public.

Barbie’s role in this occupation is purely for others to gaze at, lacking any substantial career prospects. The Barbie Media webpage presents various other career options that are deemed gender “appropriate” such as fashion editor, ballerina, ice skater, Miss America, Aerobics instructor, and more (barbiemedia. com). These careers primarily revolve around fashion and Barbie’s attire, with little emphasis placed on the actual duties involved.

During the second wave of feminism, these jobs represent typical professions for women and restrict Barbie from pursuing career paths that are not centered around fashion. However, in the third wave era, Barbie embraces careers that were previously and are still predominantly held by men. A recent addition to the Barbie “I can be” line is Barbie architect. This profession portrays Barbie clad in conservative attire, including a jacket, a hard hat, blueprints, and a dream house to complement her outfit.

The inclusion of Barbie in traditionally male-dominated professions is a significant and progressive step in the “I can be” line. Notably, the Presidential Barbie represents the most groundbreaking version of Barbie to date. Although there have been several Presidential Barbies during the third wave era, this paper will specifically focus on the 2012 edition. Similar to her predecessors, this Barbie wears a conservative pink suit with a knee-length skirt and a jacket covering most of her skin. However, her distinguishing feature is the addition of platform shoes that allow her to stand independently for the first time in 53 years. This not only showcases her independence but also emphasizes her leadership qualities as she doesn’t rely on anyone for support. The fact that she is running for President and embodies stability speaks volumes about the kind of woman this Barbie aims to portray. Furthermore, the Presidential Barbie features a platform called ‘5 ‘B’s’, which stands for ‘B’ a dreamer, ‘B’ creative, ‘B’ informed, ‘B’ confident, and lastly ‘B’ involved.

Barbie’s platform showcases empowering messages for young girls and their futures. Also, a noteworthy aspect of Presidential Barbie is that Mattel, the creator of this new doll, collaborated with The White House Project. The mission of The White House Project is to promote women’s leadership in both business and politics (thewhitehouseproject.org). The partnership between Presidential Barbie and this project, which aims to empower women in male-dominated careers, solidifies Barbie as a symbol of progressiveness.

Although young girls who play with Barbie may not resonate with this, it is the parent’s responsibility to stay informed about the strides Barbie is making. Barbie has taken on various progressive careers, such as being a Unicef Ambassador, a business executive, a computer engineer, and a dentist (barbiemedia.com). When comparing Barbie’s occupational progressiveness since the second wave to her counterpart Bratz dolls, she appears to be a more viable option for young girls.

Bratz dolls are characterized as pop stars who relish in wearing makeup and frequenting trendy nightclubs on a nightly basis. Their sole objective is to revel in parties, and any insinuation otherwise would be inaccurate. Bratz dolls are frequently considered less forward-thinking compared to Barbie and fail to convey positive messages for young girls. Nonetheless, Barbie possesses an exceptional capability to captivate and deeply connect with little girls in a manner that few other toys can achieve. No matter what endeavors Barbie undertakes, she effortlessly brings them into the realm of women while also possessing the power to make certain career paths appear natural and appealing to young girls.

Even though she may not possess the physical appearance and physique that is deemed attainable, the phrase “I can be” aims to encourage young girls to aspire to attainable professions. Despite the fact that the “I can be” line includes job roles that are typically associated with women, such as ballerina, fashion designer, babysitter, and flight attendant, these career options must remain available. This is crucial in order to prevent young girls who aspire to pursue these careers from facing criticism for their choices.

Barbie now enters male-dominated careers, providing girls with more choices and options. This is a significant contrast to Bratz dolls, when considering Barbie’s traditional dominance in women-dominated careers. If we exclude the comparison with other dolls like Bratz, does Barbie’s inclusion of new careers still represent progress? For example, with Presidential Barbie, she inspires and delivers a hopeful message to young girls.

However, despite her aggressively pink outfit and platform shoes, they still allow her to maintain her femininity and stay within the realm of women. So, does she truly challenge the barrier and enter the male-dominated world of work? This poses a conflicting situation. On the one hand, Presidential Barbie represents a positive step forward in terms of career choices. Yet, the manner in which she is portrayed in this profession poses an issue. Undeniably, Barbie running for President is a progressive move. However, as Sue Stern points out in her documentary Barbie Nation, she is “pink coated” with her choice of attire.

The text points out a contradiction in Barbie’s appearance as she embodies both progressiveness by running for President and femininity by wearing pink. This contradictory aspect of Barbie’s image can be seen as both a gain and a loss of progressiveness. On one hand, her increased emphasis on the color pink can be seen as regressive, returning her to her traditional, stereotypically feminine look. On the other hand, this particular outfit includes even more pink than previous versions of Barbie, indicating some level of progressiveness.

Examining the question of whether Barbie is progressive or regressive when viewed individually, separate from other options available to young girls in the market, reveals the complexities of audience perception and consumer preferences. However, it also raises the inquiry of what alternatives exist. Unfortunately, there is a scarcity of options for young girls’ toys, as observed through an analysis of Toys “R” Us. The dominating presence of Barbie, Bratz dolls, and Disney Princesses within the store signifies the limited choices. Upon entering the store, young girls’ attention is immediately captured by a wall displaying Barbie dolls on their right. Further exploration is necessary to find a few alternatives, as Barbie, Bratz dolls, and Disney Princesses occupy a significant amount of store space. Four entire walls are dedicated to Barbie alone, while one full wall is dedicated to Bratz dolls and Disney Princesses.

Toys “R” Us has a dominant selection of toys for young girls, prominently displaying three popular choices: Barbie, Disney Princesses, and Bratz dolls. These options occupy a significant amount of space while the other alternatives receive much less attention with only a small dedicated section or stand. The overwhelming variety and appeal of these three choices make the other options appear insignificant and uninteresting to young girls. Additionally, Barbie extends her influence beyond the toy section by having her name featured on scooters and bikes in the bike and scooter section.

In the party section of Toys “R” Us, young girls can celebrate Barbie-themed birthdays with Barbie napkins, hats, streamers, and more. Barbie dominates the entire store by being prominently placed at the front, in the middle, and even at the exit. This solidifies Barbie’s control over Toys “R” Us and constantly reminds young consumers of her influence as they navigate through the store. By strategically placing more Barbie products at the exit, the image of Barbie is etched in the young consumer’s mind until their next visit, perpetuating this cycle.

Although there are other options available to young girls, both positive and negative, Barbie, Bratz dolls, and Disney Princesses dominate the market. This leaves parents with a decision: either disregard this monopoly and buy the “others,” or inform their children about these popular toys that immediately captivate any young child. It is commonly thought that parents have the ability to choose the most suitable doll or toy for their child.

Regardless of parental desires, children often acquire toys, dolls, and video games without consent. This can occur during school recess, at friends’ or relatives’ houses, or through exposure on television or in advertisements. Rather than forbidding young girls from accessing toys like Barbie or Bratz dolls, parents should educate their children about the positive and negative aspects of each toy, as well as its level of progressiveness or regressiveness.

According to Kathryn Fischer, the provision of toys for parents is primarily dependent on education. Instead of granting or refusing toys outright, Fischer suggests that children should be presented with ideas and perspectives to interpret them. She asserts that children will naturally make their own choices and discoveries, irrespective of parental consent. Interestingly, denying a toy from a child often sparks even greater interest and motivation for the child to play with it regardless.

It is important for parents to educate their young girls about Barbie, highlighting both the positive and negative aspects of her while emphasizing that she is not a human. However, the most crucial lesson is to teach them respect and love for all women, regardless of their choices. Fischer emphasizes the importance of parents encouraging their daughters to accept and appreciate their natural bodies, without demeaning or vilifying women who choose to alter or utilize their bodies for sexual empowerment (60).

When young girls begin playing with Barbie dolls and looking up to them as role models, it is necessary to give children a comprehensive education about Barbie. This involves acknowledging both her positive attributes and negative aspects, which may vary depending on individual perspectives. While some parents may perceive certain qualities of Barbie as unfavorable, others may see them as advantageous. It is crucial for children to grasp that Barbie is not a real person and that certain elements of her appearance and lifestyle may be unattainable. However, it is also important for children to recognize that some young girls and even adult women might aspire to emulate Barbie’s looks without facing criticism.

In Fischer’s view, children should not have their choices limited in exploration and play as a means to dismantle the current racist and patriarchal societal structure effectively. To create lasting change, parents should engage in open conversations with their children, encouraging them to make loving choices in life (61). Both parents and children have the power to influence this transformation. By exposing children to different options and educating them about these choices, they are less likely to deviate from their parents’ preferences or engage with disapproved toys. Instead, they will comprehend why certain dolls or toys are favored by their parents. An example of this is Barbie, which is a beloved doll among young girls. Compared to Bratz dolls, Barbie can be seen as more progressive for girls because she represents various career possibilities. Barbie’s Architect and President dolls under the “I can be” collection symbolize progress made since the second wave feminist movement when traditionally feminized professions were associated with her.

Bratz dolls have no occupation but are known for being professional partygoers. In contrast, Barbie is a positive role model for young girls. Through the “I can be” line, Barbie shows that girls can pursue any career they desire. However, when not compared to alternatives like Bratz dolls, Barbie’s progressiveness is called into question.

Despite Barbie’s campaign showcasing the power of women in male-dominated careers, her clothing contradicts this message. Compared to previous career outfits, Barbie’s current attire is excessively pink and emphasizes her femininity. This contradictory image raises the question of whether Barbie’s perceived progressiveness when standing alone, supported by her platform shoes, is genuine. Alternatively, she may simply remain the same regressive doll. Ultimately, Barbie’s regressive outfit undermines the progressiveness of her chosen career.

Young girls often feel compelled to play with Barbie dolls due to the limited availability of other options for them. Even when other options are available, they are typically scarce or not well-represented in toy stores. As a result, children are inclined to desire the most popular dolls, such as Bratz dolls and Barbie dolls. Consequently, it becomes the responsibility of parents to provide these popular dolls to their children, while also prioritizing the importance of educating them about these dolls. Education empowers individuals with knowledge, enabling them to make informed decisions that they believe are in their best interest.

When children are given a Barbie doll, it is crucial to educate them about both its positive and negative attributes. This allows children to decide what they will adopt from the doll. Equally important is for young children not to judge others on their preferences and choices for emulation. Ultimately, whether the toy or doll is progressive or conservative, the key to fostering imaginative play is ensuring that children are well informed about the toys they play with and imitate.

Effects Of Biotechnology In Healthcare

Technology continues to have a major impact on healthcare and how it’s delivered in the U. S. The use of the technological developments in healthcare is what raises basic questions and the issue of whether or not it is ethical or moral to do so. The technology and research used in the US have no ranked one of the highest, are known as the best worldwide, and have therefore allowed Americans promising breakthroughs in the areas that include cancer treatments, surgical treatments, innovations in biotechnology and pharmacology.

The advancements in genetic research has allowed the world of medicine to better understand perplexed medical conditions and the abilities to soon prevent or reverse many inherited conditions with the help of genetically engineered drugs. Along with many controversial ethical issues involving healthcare, biotechnology is an area that poses a dilemma and raises a moral debate. In all, biotech has improved human healthcare and enabled biotechnologists to develop ways to give faster, more precise tests and therapies with less side effects.

Key New Developments in Biotechnology Biotechnology had been described as “the chemical processes and products of a range of organisms discovered empirically” (Butterworth-Heinemann, 1991). The main challenge of biotechnologists, with new metabolic processes and their interrelationships being developed, was the inheritance and regulation of synthesized enzymes and myriads. This challenge over the years has been met thanks to molecular genetics which have provided tools for biotechnology use in many areas across healthcare.

The future of biotechnology is so promising due to the sophistication of modern biological sciences. It includes introducing genes of plants and animals to create transgenic organisms and developing innovative treatment and therapies for patients suffering from chronic disease. New and The Effects of Biotechnology in Healthcare 3 unexpected ways of doing things has and continue to be the excitement of innovation for the field of biotechnology. What is Biotechnology in Healthcare?

I reference to healthcare, biotechnology, also referred to as healthcare biotechnology, According to The European Association of Bioindustries, is a medicinal or diagnostic product or a vaccine that consists of, or has been produced in living organisms and may be manufactured via recombinant technology (2009). This form of technology has the mission of targeting the disease and offers new solutions to patients which include; higher clinical effectiveness, and superior therapeutic and diagnostics approaches (EuropaBio, 2009).

The European Association for Bioindustries explains that biotech produces information used to alter and improve cell behavior in areas that include medecines (gene therapy), vaccines and diagnostics. Overall, biotechnology in healthcare offers high hopes to treat patients with disease. Biotech has strongly increased the efficacy and number of diagnostics The advances in biotechnology has allowed for the direction of medical conditions more accurately and quickly.

Take the biotechnology based tool of home testing kits for example, the newer generation of this product give results that are more accurate than earlier ones and can be used at earlier stages of disease (HIV, Hepatitis C). The diagnosis of infectious diseases can now be made early on, making it possible for early treatment, unlike tests used prior to the use of biotechnology. Now with the use of biotech in diagnostics, simpler blood test allow doctors to measure the amount of “bad” cholesterol in the blood and also eliminates the need for expensive and invasive surgeries in regards to certain types of cancer (Ovarian, Prostrate).

Previously the aforementioned diseases were diagnosed The Effects of Biotechnology in Healthcare 4 much later some even after signs and symptoms began. The benefits of biotechnology as a whole offer not only cheaper tests that are quicker and more accurate, but it enables physicians to diagnose issues early resulting in much greater prognosis. Biotechnology based tools has and continues to make improvements in health care services provided to patients. Treating the Cause of the Disease Instead of Symptoms will greatly increase

The causes of morbidity and mortality have changes over the past century from infectious disease to chronic disease. This shift is the cause and effect of the increase in life expectancy and raises the question of whether biotechnology companies and research in academia can help those living with chronic illness live longer lives. In his article as a guest columnist, Christoph Wetphal states that “These new types of cures are likely to reach the market over the next 30 years based on compelling research in academia and biotech” (2010).

Westphal also explains the 1st approach at increasing longevity known as regenerative medicine. As people age many develop organ malfunctions, similarly as one would see with cars for example. As the car gets older and more miles are added, then the parts begin to fail. For humans it seems that disease is the cause of our damaged organs. Surprisingly, humans have stem cells that can replace organs and tissues. Because of this, body functions can be improved by stimulating those cells and using them as replacements.

Advances in medicine enable people to live with chronic illnesses. In the future biotech should and might increase the life span of human beings with regenerative medicine. Biotechnology promises to treat the disease instead of the symptoms as in cystic fibrosis, which is a disease that negatively affects the ion pumps in cells, In return gastric and respiratory symptoms develop. Gene therapies are in the process of delivering normal copies of the defective gene, allowing cells to make working ion pump version that will ultimately cure the disease.

The development of gene The Effects of Biotechnology in Healthcare 5 therapy offers high hopes of cures for chronic diseases including cancer and cystic fibrosis. The results will decrease genetically chronic diseases and overall increase in life expectancy. Future of Biotechnology in Healthcare The future for biotechnology will be able to offer patients better and more choices in healthcare. The advances in therapy and diagnostics will continue to change the way disease is prevented, treated, and possibly cured.

This shift in healthcare holds great potential to improve the lives of critically ill patients and a concomitant to increase longevity. Personalized medicine, pharmacogenomics, gene therapy and stem cells are just a few areas that will be impacted by the innovative changes. An Amgen scholar, a national and international research program, defines personalized medicine as the concept in which patients should be treated with therapies and medicines based on each patients unique genetic makeup. This concept is different from the standards that are used currently to practice medicine.

Today averaging the responses of large groups of people is what determines the standard of care. This new technique of personalized care will manage the disease of a patient based on age, gender, weight, diet, along with other specific characteristics. Genetic testing will also continue to be included in personalized medicine. This has allowed care to be given based on genotype. This issue of which drug and the amount to prescribe that will work for an individual or those groups of people, who have the same genetic makeup, is the challenge of a movement referred to as pharmacogenomics.

Again, according to Amgen scholars, this area of healthcare takes advantage of the ideas that individuals have unique genomes and each person’s genetic makeup will react differently to a drug and the dosage taken. In understanding the makeup of individual patients, doctors can prescribe the best possible drug and the correct dose that will work well with fighting a particular disease. The advancements in personalized medicine and pharmacogenomics together will allow researchers to The Effects of Biotechnology in Healthcare 6 Target the diseases at an individual level and enables physicians to address the needs of that patient individually.

These two areas in healthcare will improve clinical trials for new medications and allow more advanced screening for disease, explains information provided by Amgen. Using these two hand in hand will result in more efficient and effective preventive care and services. Gene therapy concentrates on patients who have deadly diseases and have very little treatment options available. In the future, the technique will allow doctors to insert a gene into a patient’s cell, replace the “bad” or mutated genes with healthy ones or introduce a new gene to treat a particular disease or disorder.

Stem cells are cells that can develop into different types of cells and can be used a repair system for the human body. Stem cell therapy which involves growing the cells in a laboratory and directing them toward a specific cell, is another new innovative therapy used in healthcare. Still in the experimental stages of research, this therapy aims to replace damaged cells will healthy cells by performing surgery to put them in place with intentions of having the cells replaced and reversing the already damaged cells.

This theory might also be referred to as regenerative medicine—-hence what is actually does. This cell replacement process would open doors to treat or cure many chronic illnesses. New Drug Delivery Systems Microspheres are also being studies y biomedical researchers aiming to guide drugs to their intended targets. This development will allow doctors to improve the effectiveness of treatment and the overall health of patients.

As of today these microscopic particles that carry the drugs to their sites, are available for lung cancer and respiratory illnesses. Main Ethical Issue in Biotech Healthcare The Effects of Biotechnology in Healthcare 7 The costs and access to treatment is one of the many ethical issues regarding healthcare biotechnology. Drugs such as erythropoietin, used to restore blood supply in caner patients or TPA (Tissue Plasminogen Activator) used to break up clots in patients who have suffered from heart attacks or strokes due to clotting, have become expensive.

Generally U. S. insurance companies will cover the costs of these drugs however; this might not be the case in other countries. I this particular issue, biotechnology promises to eventually increase drug discovery productivity and increase the number and availably of new drugs. According to Gibson (2008), “Biotechnology in the future may also lead new ways to clean up contaminated environments and the pollutants and wastes mankind produces……. ith the population of the world needing better healthcare, cleaner air, water and food, biotechnology can hopefully provide some answers. Healthcare and its delivery will change in great depths in the years to come. Genetic testing will create advances in new innovative diagnostics and therapies, changing even how diseases of the human body are prevented, treated or cured. Drug producers will take a more active role in providing treatment to patients and health information to those living healthier longer lives than in previous years.
