Use of pesticides against pests

As pesticides are used to kill the pests that feed  on crop and may also cause some viral and bacterial diesases in plants as well. The pesticides that are actually poisons not only kill the pests but also damage the human health. The major serious diseases caused by pesticides are hair loss, skin alargy and cancer. When the plants are sprayed with the pesticides these plants aslo absorbed the chemicals that the pesticides sprayed in the body parts as stem, leaf or fruit. when the consumers even the pests feed on the plant parts will be harmed.
On the other hand pesticides also have a major and important fact that it have the ability to leach down in earth and mix with underground water. these pesticides have ability to survive the sun heat and environmental factors and maintain its chemical structure. DDT is the best example of these type of pesticide. The use of DDT was banned in the United States in 1973, although it is still in use in some other parts of the world. The chemical stability of DDT and its fat solubility compounded the problem. Thats why it was banned.

 It is clearly mention on pesticides bottles that it's dangerous be aware. Its means thats its a poison. When the plants absorb the poison it remains in the plant tissues without any alteration in the chemical structure because the plant metabolism is failure to break down the chemical structure of the of the pesticides. This type of chemistry is useful for pest control but harmful for human health.
As being human being and have senses, Its easy to understand that if an pesticide can damage the insect's body syetems than why not other's body system? Here is the main theme of the article that if a pesticide effects the insect's nervous system than who an ohter consumer is it a bird, animal or what ever will be safe?Use of pesticide should be minimized on vegetables and fruit crops especially. It's a slow posoning that the human consume and when the posion level reaches to its level it harms the victims.
