Methane and Global Warming

Another gas that contributes to global warming is methane. Methane is produced when things break down, or decompose, without oxygen. Two major man-made sources of methane in the United States are landfills, or dumps where we bury our garbage, and large animal farms that raise animals for meat and dairy products that many of us eat.

Burning fossil fuels is creating more carbon dioxide than is healthy for the planet. It is possible to get our energy and electricity from other sources like the sun and the wind. Solar power and wind power don't pollute or create greenhouse gas. One day, we'll be getting most of our energy from these alternative, or different sources of energy.
