The most practical way to prevent global warming is to not use as much of the stuff that creates greenhouse gases. On a local level, you can help by using less energy. The electricity that is needed to power our electronics comes from power plants, which burn fossil fuel to produce electricity. Here are a few specific ways that you can help lower emissions:
• Turn off lights when they are not in use. Although the light bulb itself does not emit gases, the power plants that are powering it do.
• Whenever possible, use a fan instead of air conditioning.
• Keep your car tuned up. When it is running properly, it emits fewer harmful gases.
• Walk or ride a bike when you can.
• Recycle. Un-recycled garbage ends up in a landfill, which produces methane. In addition, recycled goods require less energy to produce than products made from scratch.
• Plant trees and other plant life where you can. Plants take carbon dioxide out of the air and release oxygen.
• Don't burn garbage. This releases carbon dioxide and hydrocarbons into the atmosphere.
The most effective way to stem the emission of greenhouses gases is to develop non-fossil fuel energy sources. Hydro-electric power, solar power, hydrogen engines and fuel cells are all ways to cut down emissions.
