Here are some tips to reduce your impact on the greenhouse effect and save wildlife: * Lower your thermostat in the winter and raise it in the summer. * Replace your regular light bulbs with energy-saving florescent light bulbs. * Keep your car tuned-up and observe speed limits. Whenever you can, leave your car at home. Instead, use public transportation, walk, or ride your bike. * Plant a tree. Trees absorb carbon dioxide and also provide protection for wildlife. * If you buy coffee and chocolate, choose organic versions. The coffee and cacao plants in the tropical rain forests of Latin America help sustain migratory birds.
