Global Warming is a long-term warming of the planet's temperature and its pace has increased over the past few decades because of the increase of burning fossil fuels. It has increased because of the population growing rapidly and it's causing the greenhouse effect on the Earth's atmosphere.
The greenhouse effect is when the sun's rays penetrate the Earth's atmosphere but the heat cannot escape into space. It's because of the gases that trap the heat from leaving Earth's atmosphere and it's caused by burning fossil fuels. The greenhouse gases can be carbon dioxide, water vapor, methane, or nitrous oxide
Humans are contributing to global warming by increasing the burning of fossil fuels which also increases the greenhouse effect. Since the Industrial Revolution in the late 1700s, the greenhouse effect has increased in quantities and has caused many new problems.
Deforestation
Humans can release carbon dioxide by cutting down forests, because decaying plants including trees, release tons of carbon dioxide into the atmosphere, and living trees absorb carbon dioxide, so if we cut down more and more trees, the gas will remain in Earth's atmosphere.
Livestock Farming
Raising cows for meat and milk releases tons of gases like methane and nitrous oxide because of the digestion and manure breakdown and agricultural technology also produces Nitrous Oxide.
Transportation
Transportations like cars, trucks, motorcycle, planes, or tractors, all of them contributes to the greenhouse effect by producing tons and tons of carbon dioxide. Even many electric power plants also use burning fossil fuels.
