Negative effects of pesticide on the environment?

Answer 1

Pesticides are poison. Some of the better pest controls are now using baits that attract the pests and then trap them in a (harmless to humans) area or on a sticky surface. The traps then can be safely disposed of limiting the exposure of pesticides to humans.

Pesticides can kill off some of the use full insects on the plants. Like Greenfly drink the sap from the stems of cabbages, this is helping the cabbages and the farmers. So, by using pesticides you can actually be destroying insects that are not even pests!

Answer 2

Pesticides generally poisons and repels pests on crops. While it makes the crops untouchable, it also kills the soil. Also the effect of pesticide is just the same as synthetic fertilizer. The synthetic fertilizer fertiles the soil but the life span of the soil shortens and when it dies, any fertilizers even the best one won't have any effect on the soil.

Answer 3

Chemical pesticides are the main reason for all the health problems in humans.

Now proceed to all important point whether we should consider money or ourselves first. Prolonged exposure to pesticides in humans can lead to severe disorders in our reproductive, nervous and immune system PLUS in some cases can even lead to cancer. Exposure to some pesticides can be 'hell' for a pregnant lady as it can easily lead to death of baby and even if the baby is produced will have lots of disorders or even loss of limbs.

However, pesticides are not like poisons where a very small amount can be deadly but we need to always, if possible, protect ourselves from exposure to pesticides. Farmers can use mouth masks or other accessories to keep them away from intake of pesticides.

On the positive side, without pesticides and a the plethora of other agricultural chemicals, food production would be much lower and thousands )if not millions) more people would be malnourished and potentially dieing from hunger. From a strictly technical point of view man made pesticides are narrowly focused against a particular organism and only kill it. Natural pesticides as found in many plants are more broad spectrum, killing everything.
