Today, you will read General Awareness Topic: Pesticides are necessary evil
Pesticides are used by farmers, housekeepers, and maids to eradicate pests, including cockroaches, rats, insects, and microbes. Farmers spray pesticides on plants, trees, fruits and vegetables to keep pests away.
Also, by spraying pesticides on plants and trees, farmers can mitigate a number of diseases that harm plants and trees and result in their death. In addition, pesticides prevent the growth of weeds, leading to the healthy development of other useful plants and trees.
Even though pesticides were manufactured for the greater good and benefit of mankind, it has a number of drawbacks, the most important drawback being potential toxicity to humans and other animals.
Sadly, most of us do not wash fruits and vegetables properly before consuming them, and as a result, we end up consuming traces of pesticides. Small traces of pesticides are relatively harmless to humans, but frequent exposure to such pesticides can be harmful to our health and in extreme cases, it can be fatal.
Studies have shown that exposure to pesticides can result in the irritation of the eyes and skin, vomiting, diarrhoea, cancer, and breakdown of the nervous system. This is one of the reasons why many people are shifting to organic food.
Although organic fruits and vegetables are slightly more expensive than those grown the traditional way, they do not contain any traces of pesticides, making them 99.9% harmless to humans.
In organic farming, chemical pesticides are not used; instead, natural pesticides like snakes are used. So, in organic farms, snakes are released into fields to catch rodents and other pests that are harmful to trees and plants, ultimately making organic food safe for consumption.
The World Health Organisation and the United Nations Environment Programme have conducted some studies, which show that every year, close to 3 million farmers in the developing world experience severe poisoning because of pesticides.
Another study showed that pregnant women who stay close to farms and fields sprayed with pesticides are more likely to give birth to babies with autism.
Pesticides are not just used on farms but also in homes to keep cockroaches and rats at bay. However, pesticides that are sprayed on walls and floors are harmful if not cleaned immediately. If there are pets or small children in the house, it is important to clean the remnants of pesticides immediately to prevent its accidental consumption.
Pesticides are also harmful to the environment. When pesticides are sprayed on soil, plants, and trees, the harmful ingredients seep into the soil and contaminate it.
Pesticides in the soil ultimately enter water systems and cause water pollution. Pesticides are not just harmful to man but also animals. So, once marine animals consume pesticides, they die a painful death. Pesticides threaten the existence of endangered species and create chaos in the entire food chain.
Due to the harmful effects of chemical pesticides, farmers in India are shifting to Panchakavya, a concoction prepared by mixing cow dung, cow urine, cow milk, curd and ghee.
Once they are mixed in the proper ratio and left to ferment, the concoction can be used as organic pesticide. Also, the concoction can be used as a fertiliser to enhance the growth of plants and trees. Since there are no chemicals involved in the making of Panchakavya, there are no side effects and drawbacks to its usage.
