Question 1 Rachel Carson’s basic thesis in Silent Spring is to discourage the use of the many pesticides and herbicides that we are putting on everything. By the use of these chemicals, they are traveling and infecting many plants/animals that were not planned. Examples would be honey bees and humans. Rachel Carson is mainly concerned on DDT (dichloro-diphenyl-trichloro-ethane) that was discovered by Paul Muller. He won a noble prize for the creation of it; this was before DDT was found harmful to the environment and deadly for humans. Carson explains the make-up of DDT and the negative effects of it along with many other chemicals that are used daily.

Dieldrin is another very toxic chemical; it is about forty times more toxic than DDT. Chlordane can enter the body in many different ways. Once it is in the body, it builds up in the lipids. Other examples would be chlordane, Aldrin, and DDT. The other class, organic phosphorous also known as alkyl, are the most dangerous chemicals of them all. These chemicals have the ability to destroy enzymes in the body causing much harm. Examples of these chemicals would be starting with Parathion, the most well-known and hazardous organic phosphorous chemical. Parathion can have a great effect on honeybees.

These alternatives were biological solutions, meaning that they have more understanding what they are going to do to the organism that they are treating and most importantly the other organisms surrounding. The first alternative that she described first was a technique called “male sterilization” which was created by Dr. Edward Knipling. Male sterilization is a technique to control insects. The thoughts on this process are to introduce large quantities of sterile insects into the ecosystem and then they would compete with wild males and only infertile eggs would be produced affecting the population to die off. A negative thing about the sterilizing effect is that it takes longer to test compared to testing chemical poison. Another alternative mentioned in this chapter was sound. The use of ultrasonic sound can kill mosquito larvae, although the negative effect of this is that it harms and can kill aquatic life. The attempt to kill insects with sound is effective. Introducing natural enemies to control unwanted pests is the safest alternative in this chapter in my eyes. This method does not involve the use of chemicals, making it where it has little to no harm to the environment. Another positive to this alternative is that it is also very cost efficient and long lasting. This method works best in forests. Rachel Carson gave many examples of this process, explaining
