December 3rd world population celebrates the International Day against pesticides. The choice of this date preceded the tragic events. December 3 in 1984 on pesticide plant in Bhopal (India), there was an ecological disaster in memory and which was established this day.
The goal of the day against pesticides — to draw global attention to the problems caused by the production and use of these hazardous chemicals. Pesticides — are synthetic chemicals that many countries in the second half of the 20th century, is widely used to increase crop yields.
However, as it turned out, the industrial production of these chemicals to the population of the planet has brought more harm than good. Pesticides beat not only the goal, allowing high yields with rural fields (which, incidentally, was also later questioned), but also on the water, soil, plants, animals and people, causing them irreparable harm.
In the last decades of the 20th century in a number of pesticides have become one of the most important risk factors for human health and life, and the whole of nature. If the USSR in the 60's of last century, the number of pesticides per capita per year did not reach one kilogram, then by the end of perestroika it increased three-fold. It pesticides, according to UN experts, have become a major cause of the "silent catastrophe" — the so-called current state of soils in Europe. Moreover, it turned out that pesticide resistance is so high, and their distribution globally so that they are found even in the bodies of penguins in Antarctica, where pesticides have been brought by air and ocean currents.
The consequences of chemical effects on the biosphere deplorable. They lead to different mutations and diseases in humans and animals, to the disruption of the reproductive and hormonal systems, immune status, to cancer and birth defects.
Now in contrast to the "pesticide" agriculture scientists put forward the concept of " organic farming ", based on a combination of different types of plants, the natural control of pests, replacing chemical fertilizers to organic. However, the question of when this concept will find a large-scale practical application is still open.
