My daughters have traveled in China. They said everything, especially around Beijing, looks dingy and gray from all the air pollution. They burn soft brown coal for power and heat. Brown coal burns very dirty. It not only pollutes the air, but it also contaminates the ground. My oldest daughter has traveled widely and lived in many countries. She said China was the filthiest place she has ever been.
After hearing my daughters stories and seeing the news reports of contaminated pet food, milk products and other foods being imported from China I started buying as much locally grown food as possible. Better for the environment and supports local agriculture. My fruits and veggies come from a food share at a nearby CSA (Community Supported Agriculture) farm. Beef, pork, lamb (raise chickens myself) I buy from local farmers and have processed by a local butcher. Healthier, keeps the money local, less fuel wasted on transportation, and teaches my youngest kid where food comes from. By buying in bulk it is also much cheaper than the grocery store. Quality better, price is better, what's not to love!
In the future I want to raise meat rabbits and quail. I also want to put in an herb garden this year.
