Pesticides have been sprayed on food for years and years but recently studies have shown that over 50% of produce sold in the U.S. has pesticide residue even after washing.
Pesticides have been found in outdoor samples in areas no pesticides have been sprayed; this is called pesticide drift which effects air quality.
To make things worse these pesticides settle in the soil and can take years to break down and dissolve. Coupled with pesticide drift soil is being contaminated in areas that are not even being sprayed.
Some pesticides even break down ozone in the stratosphere such as methyl bromide which is used to fumigate soil.
There are other ways to protect our crops that don't involve harmful chemicals such as PureCrop1 which is a revolutionary non toxic spray to prevent mildew and bugs within crops.
With a united effort we can force legislation to stop using harmful insecticides and replace them on a massive scale with PureCrop1.
