Global Warming

Global warming is the rise of the average temperature of the Earth’s climate system. Harmful gases such
as carbon dioxide and methane usually cause this environmental problem. Greenhouse gases stay in the
atmosphere for a long time. In other words, it traps heat near the surface of our planet. Unfortunately,
some human activities increase the amount of greenhouse gases and trap more heat. People must stop
releasing harmful gases into the atmosphere. Burning fossil fuels is another situation that causes global
warming. Global warming will have more negative impacts on humans, many species of wildlife in the
world. Sea levels are rising, some ice caps are melting in the Arctic and our home planet is warming up.
Adopting to new habitats or weather conditions will be difficult for some animal species, so they may
become extinct. The first thing to do is to reduce the greenhouse gas emissions. Planting more trees and
using renewable energies are two other ways to find a solution to the problem. We need more trees and
forests to provide clean air for us and animals to breathe.
