Environmental Studies - Essay Example

            One advantage of animal testing is that it helps researchers to discover treatments for both animals and humans.  One of the disadvantages of animal testing is that it can be misleading since animals may react to drugs in different ways as humans. In addition, animal testing leads to the mistreatment of animals. Testing on animals is justified because it has helped researchers to discover many effective treatments. Additionally, animals should be used because their lives have less value compared to humans.

Q2.

            Testing upon animals can give accurate results because the bodies of most animals used for tests function like humans.  Scientists have proved that lab animals and humans do not have a big difference. In addition, most of the drugs used today were discovered through animals testing. For instance, antibiotics and HIV drugs used by humans today gave positive results when tested on animals. Other methods of testing are less effective compared to animal testing.  In addition, surgery and organ transplant techniques used on humans today were acquired through animals testing.

Q3

            Tyrone says that rats are the most relevant animals used to simulate humans in laboratories. Humans cannot be used in labs tests because it will be unethical to expose to humans’ chemicals during lab tests. According to him, the use of rats produces accurate results because rats have regular reproduction, genetic purity, and many resemblances to human biology (Hayes).

Q4

            If I were a farmer, would not use atrazine to increase my crop yield. This is because the herbicide will only increase yields for a short period since it causes land degradation. Additionally, it will negatively affect my health. Research outcomes show that it causes obesity and cell mutation.

Q5

            Additional ways of increasing crop yield apart from using chemicals encompass organic farming. In organic farming, one uses decomposed animal products or plants to fertilize lands instead of chemicals. This is the most effective way of producing crops since it does not harm the ecosystem and human health. Chemicals degrade the soil since they destroy its structure and kill microorganisms. In addition, it destroys aquatic life after being transported into the water bodies by rain.

Q6

            One can show interest in the regulation of harmful chemicals through the creation of awareness about their negative effects on both the environment and humans. This can be done through the establishment of many awareness creation programs or the media. Additionally, one can get more interest through demonstrations in agricultural shows where farmers can prove the effectiveness of non-chemical methods of farming. This will help in making many farmers gain trust in non-chemical methods. It will also motivate many people to reduce the amount of chemicals food processing.
