Question

How is global warming caused? Who is responsible for it? How?

Answer 1

Global warming is caused by human activities such as burning fossil fuels, and farming.

Burning fossil fuels

When we burn fossil fuels like coal, and gas to create electricity or power our cars, we release CO2 pollution into the atmosphere.

Farming

Animals, livestock like sheep and cattle, produce methane, a greenhouse gas. When livestock grazed at a large scale, as in Australia, the amount of methane produced is a big contributor to global warming.

Some that farmers use also release nitrous oxide, which is another greenhouse gas.
