L47-1: Too high a price?
Pollution is the price we pay for an overpopulated, over industrialized planet. When you come to think about it, there are only four ways you can deal with rubbish: dump it, burn it, turn it into something you can use again, attempt to produce less of it. We keep trying all four methods, but the sheer volume of rubbish we produce worldwide threatens to overwhelm us.
Rubbish, however, is only part of the problem of polluting our planet. The need to produce ever-increasing quantities of cheap food leads to a different kind of pollution. Industrialized farming methods produce cheap meat products: beef, pork and chicken. The use of pesticides and fertilizers produces cheap grain and vegetables. The price we pay for cheap food may be already too high: Mad Cow Disease (BSE) in cattle, salmonella in chicken and eggs, and listeria in dairy products. And if you think you'll abandon meat and become a vegetarian, you have the choice of very expensive organically-grown vegetables or a steady diet of pesticides every time you think you're eating fresh salads and vegetables, or just having an innocent glass of water!However, there is an even more insidious kind of pollution that particularly affects urban areas and invades our daily lives, and that is noise.

今天的课文对我来说也是很难。生词多，课文长，从下午读到了晚上，快没声音了。看到其他同学读得很轻松，非常羡慕。但是基础差就是这样的，距离把水坑填平还很远呢，加油。
