Methane is a type of gas, the kind you breathe in the air. It is clear and has no smell. Methane comes in part from human activities and in part from nature. This gas can be both good and bad for the environment, and it’s important to learn more about it.
A gas like methane is composed of really little things, atoms. It is called a greenhouse gas because it can trap heat in the atmosphere. If it hangs in the air for too long, methane gas can contribute to global warming and a changing climate.
People can produce methane gas by, for example, farming, using fuels and handling trash. (For example, if we raise animals like cows, they produce methane gas when they are digesting food.) Nature can also generate methane gas from locations such as wetlands and volcanoes.

When methane escapes into the air, it can be a problem. It can dirty the air and produce smog, which can harm plants, animals and people. The fact that methane gas is incredibly efficient at trapping heat makes it significant for climate change as well.

Methane gas is more effective than carbon dioxide at trapping heat in the air. This means that although there is far less methane gas than carbon dioxide, it can have a long-lasting impact on global warming. It is important that we find ways to create less methane gas to help counteract climate change.

For all its faults, methane gas can be deployed for good. We can snag it and turn it into power. This entails capturing and utilizing methane gas from places such as landfills and farms and converting it into electricity or heat. This reduces the amount of methane gas that goes into the air and gives us renewable energy.
