Integrated pest management: combing ecological, biological, and chemical methods. The effective combination of three types of pest control to manage pest populations while minimizing environmental damage. The ecology of eating: food accounts for ~25% of our ecological footprint (less in developed) Consider where food is coming from (food transportation can increase footprint 10%) Use manure and legumes instead of chemical fertilizers. Know ddt and pesticide resistance case study in detail. Ozone layer: highest levels of ozone are in the stratosphere, ozone filters out sun"s uv light rays, which are harmful (but also used for production of vitamin d, ozone is produced naturally from uv rays reacting with o2. 1: safer alternative to the sulfur dioxide and ammonia refrigerants used at the time, cfcs were chosen for safety and for their advantageous chemical properties (low in toxicity, non flammable, etc) Cfc"s destroy ozone, therefore cfc"s permit increased uv radiation. Increased uv radiation is hazardous to your health.
