Reduce Greenhouse Gas Emissions.
Burning fossil fuels such as natural gas, coal, oil, and gasoline raises the carbon dioxide level in the atmosphere, and carbon dioxide is a significant contributor to the greenhouse effect and global warming. You can help reduce the demand for fossil fuels, which reduces global warming by using energy more wisely. Save electricity and reduce global warming by turning off lights when you leave a room and using only as much light as you need. And remember to turn off your television, stereo, and computer when you're not using them. It's also a good idea to turn off the water when you're not using it. While brushing your teeth, shampooing the dog, or washing your car, turning off the water until you need it for rinsing. These things will help.
