Answer to Question 1
One possible way to ensure the limited and prudent use of pesticides by consumers is to not sell concentrates. This avoids the problem of incorrect dilutions. The EPA already limits the types of pesticides that are approved for consumer purchase. This could be limited further and the quantities that may be purchased could be limited.
Answer to Question 2
China's environment has suffered greatly as a result of rapid growth. One of the examples is the toxic air. Sixteen of the world's most polluted cities are in Chinanot a distinction to be proud of. Sulfur dioxide is one of the toxins and many deaths have occurred because of it. Another example is the water pollution that is causing cancers, and related to this is the diversion of water for irrigation and other uses. The Three Gorges Dam has displaced millions of people and covered millions of acres of farmland in water. The governmental environmental regulation agency, SEPA, has its hands full and is struggling to keep up. As a result, over 2,000 more local NGOs have been formed in an attempt to slow the pollution down and affect some cleanup activities.
