Global change

Global change is when something big happens to the environment all around the world. It could be something like the air in the air getting dirtier, or the water in the oceans getting warmer or colder. It could also be a change in the plants or animals that live on the Earth, or in the amounts of rain that falls in different areas. All of these things can happen very quickly or very slowly over time, but it's all part of global change. People can help stop global change by choosing to use less energy (like electricity and gas), not throwing away our trash, and growing more plants to help clean the air.
