Background: 200 years ago, people used only organic matter such as farm yard manure, foliage etc as fertilizers and the yield was more and
also of high quality both in taste and size. Gradually, the use of natural waste materials reduced and people started to use synthetic fertilizers so
called Green Revolution. Although initially the yield was good, it started reducing year by year and finally led to poor quality of products and minimum
yield. The reason was the microorganisms in the soil were destroyed due to the unavailability of food and the excess use of chemical fertilizers,
chemical fungicides and chemical pesticides. Nowadays, even if we use more chemicals, there would be no considerable yield definitely as
there are no microbes in the soil to serve and feed the plants. This is lead to congenital abnormalities, pre-term/low birth weight, sudden infant
death syndrome, problems related to complication of pregnancy, and respiratory distress syndrome.
Objective: 1.Trend in pesticides consumption in Tamilnadu 2.the present paper is aimed at, To evaluate the correlation between life
expectancyand pesticides consumption. 3. Genetically modified food impact on human health
Methods: the present study passed on secondary data, the 10 years data collected from various statistical report published bygovernment of
Tamilndu, state agriculture plan Tamilnaduvolume-1.Tamilnaduan economic appraisal and state agriculture plan report of Tamilnaduandin
order to find out the relation Correlation coefficient has been used and the following semi log model was applied to find out the trendlogY=a+bt,
and Compound growth rate (CGR)=[Antilog b-1]x 100 also used in the present study.
Finding: the study found that pesticides consumption has been negative trend whereas bio-pesticides distribution has been positive trend in
Tamilnaduand also the study found that thesignificant correlation between pesticide and bio-pesticides consumption and human health in
Tamilnadu. The “r” value(r=-0.84) is very high and negative. Whereas in the bio-pesticides impact ratio is low the “r” value is -0.45.
Conclusion: the only solution is to multiply the microorganisms in the soil again and to increase the use of organic matter in the place of chemical
fertilizers which is increase life expectancy and reduce infant and prenatal mortality.
