How eco-friendly is cotton?
Why is cotton so important in today's energy-conscious environment?
Cotton is the largest natural fiber supplying the global demand for textile products. In 2005, the world's demand for textile fibers was 130 billion pounds. In 2006 and beyond, world income and population growth will stimulate a 4.5 billion pound increase in global fiber demand each year. That means enough fiber will be needed for nearly 9 billion tee shirts or 2.3 billion pairs of denim jeans. And the main alternatives to cotton are non-renewable chemical fibers.
Can cotton supply the market in an environmentally-friendly manner?
Absolutely. Cotton is sustainable, renewable, and biodegradable, making it an excellent choice as an environmentally-friendly fiber throughout its entire product life cycle. Most chemical fibers are petroleum based, which means they come from nonrenewable resources.
I've heard that it takes a tremendous amount of pesticides to grow cotton. Is that true?
No. According to the U.S. Department of Agriculture, only about 1.2 pounds of insecticides and 2.1 pounds of herbicides are applied to each acre of cotton. The average acre in the U.S. produces about 800 pounds of cotton. That works out to around 0.09 ounces of total pesticides applied per pound of cotton produced. More importantly, with the advent of new technology, the number of pesticide applications has dropped dramatically in the United States. Farmers who live and work on their land have every personal and economic incentive to use FEWER chemicals in production, not more! Globally, only 8.5% of all pesticides applied to crops are used to grow cotton.
Even so, aren't there toxins left on cotton products that could be harmful to one's health?
No. In the United States, cotton is regulated as a food crop by the Food and Drug Administration (FDA). Cotton is grown just like other major food crops, meaning that there are tight restrictions. Worldwide studies consistently show no pesticide residue on the raw fiber or the textile products made from the fiber.
What about water? I have heard claims that growing cotton takes a lot of water.
Cotton is very drought and heat-tolerant. Cotton does not require excessive amounts of water. In fact, cotton uses less water than many other major crops produced in this country. Only 35% of U.S. cotton acreage requires some form of irrigation-the rest of the cotton land is supplied by natural rainfall. Furthermore, producers have become more efficient in their water usage. Compared to 25 years ago, U.S. farmers are now using 45% less irrigation water to grow a pound of cotton.
What else is cotton doing long term to reduce its environmental footprint?
New technology, such as insect-resistant and drought-resistant varieties, continues to reduce the need for pesticides and water. These same varieties will improve yields, allowing for more cotton to be grown on the same amount of land. Conservation tillage practices (less plowing and disturbing of the soil) have increased dramatically in the U.S., leading to less erosion and runoff. These practices, as adopted in the U.S. from 1996-2004, have reduced CO2 emissions by an amount equivalent to removing over 27,000 cars from the road-permanently!
