The Dangers of Pesticides (Alyssa, Jui, Gaby & Alexis)

On a farm pesticides dispose of not only pests, but other beneficial bugs, and can cause human illnesses. Some of the effects from pesticides are fatal, and cause serious damage to one’s body. Over time, the pesticides will build up and potentially harm your body. But, pesticides have been a big part of agriculture. Even though pesticides kill insects that are damaging crops, beneficial bugs have also died due to the dangerous chemicals they contain. The farmers’ desire to use pesticides is understandable, but there needs to be a way to stop chemicals from entering human bodies and harming bugs that aren’t targeted. Tracing the greenhouse solution back to the original problem, our group realized if pests couldn’t access the crops, there wouldn’t be a need for the use of pesticides. Our solution is to build a large greenhouse on farms.

Our original problem was that we know people want to use pesticides, but we found that many pesticides were harmful or toxic. One cause are the toxic chemicals in the pesticides, such as Diazinon, Malathion, Dursban (Chlorpyrifos), and Carbaryl. Although Diazinon is used for controlling the soil and foliage, it not only harms pests but beneficial bugs. Malathion controls a wide variety of insects in agricultural settings. People are affected just as pests are from malathion. These chemicals harm both people and beneficial insects. Another cause of this problem is that disease carrying pests are drawn to the crops harming many of the plants. Therefore,  farmers use pesticides to save their crops from the dangerous bugs. Our group realized that the lack of pests could be a major part of our solution. If the pests weren’t there, people wouldn’t have to use pesticides at all.

Pesticides contain many dangerous chemicals, harming people and animals. When humans ingest or come into contact with the toxic chemicals in pesticides, it causes many human health problems, some of which are fatal. Health problems include permanent neurological and kidney problems, reproductive harm, endocrine disruption, headaches and nausea. Without pests, humans wouldn’t have to worry about these health difficulties, which motivated us to think of solutions to avoid the use of pesticides. The chemicals in pesticides kill harmful bugs when sprayed on plants, but may also harm or kill many beneficial bugs such as butterflies, ladybugs, and bees when sprayed. These beneficial bugs are very important because they help make the soil rich and they try to keep away harmful bugs from the farmers crops. Not only must we, as people, save beneficial bugs from the toxic chemicals in pesticides, but also save our own health.

There were a few attempted solutions to solve the problem of pesticides harming beneficial bugs as well as harmful ones. Our first attempted solution was for farmers to use an organic, non-toxic pesticide. This contributes to the solution because it kills the pests, but it wouldn’t harm any beneficial bugs. The next solution would be to spray one’s plants with pyrethrum. Pyrethrum is an organic spray containing no chemicals, resulting into killing only harmful bugs. Our last solution was to build a gargantuan greenhouse with parts underground and aboveground. Aboveground is the greenhouse. It would be made of glass so the sunlight could still reach the plants and shaped like a dome. On the ground there would be a layer of glass with holes in it, so the extra water would not be trapped in the greenhouse. When the plants take in all the water they need, the extra will come through the soil, and into the holes to the underground metal tank. From the metal tank there will be pipes that lead back aboveground into smaller tanks, where the water will then be purified. The farmers would be able to use the water continuously, and there wouldn’t be any pesticides due to the greenhouse. Farmers would farm directly in the greenhouse in the way they would farm outdoors. We chose this solution because it provided an organic environment for the crops, and there wouldn’t be any reason to spray the pesticides in the greenhouse because no pests could enter. The farmers would be able to reuse water continuously and wouldn’t travel anywhere but throughout the system. This solution clearly covers the problem of pesticides killing beneficial bugs and causing human illnesses.

    The most effective strategy in this post is that the group restated the main points in the essay and included helpful images. Something new that I learned was that pesticides can harm humans, as well as harmful and helpful bugs. This post may be improved if you did not list all the harmful chemicals and instead say more of what general pesticide chemicals do.

    This was a really good blog. It let me understand this topic really deeply. I loved how each of your paragraphs lead into the other so it flows really well. One suggestion would be to spread out the text but overall this was amazing.
