According to the EPA, over 380 billion plastic bags are consumed in the US each year. Plastic bags don't biodegrade, they photo degrade which means they break down into smaller bits contaminating the soil and waterways. Hundreds of thousands of marine animals die each year from plastic bag ingestion. You say you recycle your plastic bags, well many of those bags never get recycled. It is too expensive! And paper bags, well it is an energy and pollution issue there. It takes four times the energy to produce a paper bag than it does a plastic bag. You see where I am going here: reuse.
Organic agriculture is one way to prevent chemicals from getting into the air, earth and water. It takes one pound of chemicals to produce three pounds of conventional cotton. Enough said.
Hemp is naturally resistant to insects and therefore can be grown free of chemical pesticides. It is also fast growing and renewable.
