Insects are adapting to insecticides. Carson states chemicals do not work because nature is complex; the only methods that have worked were natural ones. Natural selection has limited populations. This is called the resistance of the environment by ecologists. When humans interfere, this resistance is hindered and populations increase. Also, Carson highlights that 70 to 80 % of the earth’s animals are insects; therefore, only nature can balance them.. Insecticides only help insects thrive by lowering environmental resistance. For example, spider mites benefit from insecticides, which then allows them to damage forests. Then their natural predators, ladybugs, are wiped out by the insecticides.

Rachel Carson The Obligation To Endure Summary

Carson talks about the danger of pesticides, insisting that we use caution because we do not know what the long term effects of the pesticides are. Since earth has a very interconnected food web when one part of the web gets impacted it affects the world on a large scale(paragraph 23). For example if you poison the little mice that run around then the predators that prey on them then it would poison the predators, since humans are among the top of the food chain we end up possibly being able to become in contact with the…

Instead of these chemicals safeguarding us, they’re actually increasing the human death rate. “It is a sobering fact, however as we shall presently see, that the method of massive chemical control has had only limited success, and also threatens to worsen the every conditions is intended to do.” Without exception, each new pesticide is further treacherous than the one before it, according to Darwin’s principle, “of the survival of the fittest, have evolved super races immune to the particular insecticide used, hence a deadlier one has always to be developed and then a deadlier one than…

Those to the east of the Rocky Mountains find residence in the Sierra Madre Mountains of Mexico and those west of the Rocky Mountains reside along the Californian coast (“Migration and Overwintering”). But within the last two decades, more than 90% of the monarch butterfly population has vanished. Research done by the Monarch Butterfly Biosphere Reserve and Iowa State University has ascribed this decline to the widespread use of glyphosate herbicides, predominantly Roundup Ready, attacking the butterfly’s habitat: milkweed (Pleasants 135). The herbicide Roundup Ready, produced by the agrochemical company Monsanto, is a leading herbicide widely used by corporations and private entities; traces of this chemical can be found all over the United States in farm croplands, local gardens, even the grounds of New York City’s Metropolitan Museum and Central Park (Lenzer). The herbicide unfortunately kills off the only weed that the monarch butterfly will lay their eggs on.…

After World War II (DDT)

During the use of DDT, after World War II, crop yields increased greatly in the United States and overseas. This is because the pesticide killed many of the insects that consumed the essential crops. Author Lillian Forman states, “After the war, DDT helped ensure that starving Europeans, not bugs, ate the crops that farmers were once more able to plant. When the chemical was made available to the American public, it was welcomed as a means of boosting agricultural production, suppressing pests, and protecting shade trees, orchards, and gardens” (Forman). Due to the increase in crop production, there was a greater abundance of crops available for the citizens of the countries that used DDT as a pesticide.…

The Use Of Pesticides In Silent Spring By Rachel Carson

Pesticides can do many things that make human’s lives easier. They can kill unwanted bugs, which are called insecticides, they can kill unwanted plants, which are called herbicides, and they can kill fungi, which are called fungicides. There are many more pesticides out there as well, each with a different job. These pesticides are meant to help make human lives better, but do these pesticides really make our lives better? In Silent Spring, written by Rachel Carson, pesticides are examined and shown how pesticides cause environmental issues far worse, than the pests humans are trying to kill.…

The only reason the plants don’t need pesticides is because they have pesticides genetically altered into them. These types of pesticide in the plants are called neonicotinoids. These neonicotinoids affect the nervous system of insects resulting in paralyzation and death. These neonicotinoids work great on insects but also bees. Neonicotinoids have killed large amounts of bees and we need bees to help the reproduction of 85% of the world's flowers and 35% of the world's crops (PSU EDU).…

Bees: Colony Collape Disease

Bees pollinate about 80% of wild plants and 84% of human grown crops in terrestrial ecosystems (Brown, 2009). The ecosystem service of pollination has the economic value in the agricultural industry worth $1.7 billion (Brown, 2009). However, global honey bee populations are in decline (Potts, 2010). With the given projections for human population growth to reach around 9 billion by the year 2050, the importance of bees to human survival is vital (Brown, 2009). The US Fish and Wildlife Service has listed over 50 pollinator species as endangered, and in the last half decade alone, wild honeybee populations dropped by over 30%, and nearly one third of all US honeybees have died due to a phenomena called Colony Collapse Disorder (CCD)…

In the article, “The Obligation To Endure” by Rachel Carson the author focused on explaining the consequences of human behavior. She explains how much harm we have done to our environment by the use of pesticides specifically referring to DDT, a pesticide that is not only poisonous to insects but to our Ecosystem as a whole. These pesticides instead of helping humanity they are having the opposite effect and are altering our nature. She could not be more accurate, pesticides tend to settle into our soil, from there they are transferred to our water supply creating a chain reaction, therefore contaminating wild life, plant life, and our water, etc. Therefore, regardless of some of the benefits that DDT can have, such as the ability to prevent…
