The Greenhouse Effect and Global Warming
What is the Greenhouse effect?
What are Greenhouse gases? Carbon Dioxide (CO 2 ) Methane (CH 4 ) –Cows and other animals –Decomposing garbage

What can we do to prevent global warming? Use sources of energy that do not emit carbon dioxide (CO 2 ) –Solar, Hydrogen, Wind, Biodiesel Reduce the amount of energy we use –Cars with better gas mileage –Energy-efficient appliances –Turning off electrical appliances when not in use.
