In an excerpt from her 1962 work Silent Spring, Carson calls upon the public to take action against the use of parathion by highlighting its catastrophic nature and vilifying the agricultural community for their negligence.

Although I feel that malathion, when correctly regulated, is perfectly safe for humans, I do not feel that it’s worth the impact it will have on the environment. Being highly toxic to important insects and fish will negatively affect the surrounding ecosystem. Once we began to deplete that, then there definitely won’t be any mosquitos left to worry

Switching from the expensive oil to alternative fuels has moved from a dream to reality. Today, there are dozens of alternatives to oil that are currently available us to be used. One alternative to oil that is being used more today is ethanol. Derived from plant materials, ethanol can be a cheaper, cleaner alternative to the gasoline that our vehicles run off. When going to gas pumps, one will notice that much of the gasoline is up to 10 percent of ethanol. According to our text, most ethanol in the U.S. is made from corn, yet ethanol can be made from any biomes-- including garbage. (Turk & Bensel, 2011)

Natural disasters occurring from the climate change could be on the rise. Global warming has been rumored to be causing more hurricanes, typhoons, cyclones, heavier monsoonal rains that cause major flooding, mud slides, and other disasters worldwide. A tropical cyclone, also referred to as hurricanes, typhoons, or cyclones, depending on where in the world the cyclone is occurring, are one of the world’s grandest shows of energy provided by nature. Hurricanes are large, swirling, low pressure storms that have sustained winds of over 74 miles an hour and are formed over warm ocean waters (NASA, n.d.). The purpose of this paper is to discuss hurricanes

The use of pesticides is an important decision that thousands of communities face each year.

All of these pests coming to steal and eat the plants can cause the land to lose moisture and lower the quality as well. This has affected the farming community greatly.
