Cotton and the Environment
Benefit of organic
Organic agriculture protects the health of people and the planet by reducing
the overall exposure to toxic chemicals from synthetic pesticides that can end
up in the ground, air, water and food supply, and that are associated with health
consequences, from asthma to cancer. Because organic agriculture doesn't use
toxic and persistent pesticides, choosing organic products is an easy way to
help protect yourself.
Here are some reasons why organic cotton production is important to the
long-term health of the planet.
Cotton uses approximately 25% of the world's insecticides and more than
10% of the pesticides (including herbicides, insecticides, and
defoliants.)
Approximately 10% of all pesticides sold for use in U. S. agriculture were
applied to cotton in 1997, the most recent year for which such data is
publicly available.
Eighty-four million pounds of pesticides were sprayed on the 14.4 million
acres of conventional cotton grown in the U.S. in 2000 (5.85 pounds/
acre), ranking cotton second behind corn in total amount of pesticides
sprayed.
Over 2.03 billion pounds of synthetic fertilizers were applied to
conventional cotton the same year (142 pounds/acre), making cotton the
fourth most heavily fertilized crop behind corn, winter wheat, and
soybeans.
The Environmental Protection Agency considers seven of the top 15 pesticides
used on cotton in 2000 in the United States as 'possible','likely', 'probable',
or 'known' human carcinogens (acephate, dichloropropene, diuron, fluometuron,
pendimethalin, tribufos, and trifluralin).
In 1999, a work crew re-entered a cotton field about five hours after it
was treated with tribufos and sodium chlorate (re-entry should have been
prohibited for 24 hours). Seven workers subsequently sought medical
treatment and five have had ongoing health problems.
It takes roughly one-third of a pound of chemicals (pesticides and
fertilizers) to grow enough cotton for just one T-shirt.
