Before Global Warming the Earth was happy and the weather was cold. The animals roamed freely and were exposed to clean air and a healthy planet.
During the process of Global Warming, buildings , cars, and more were being created that formed unhealthy gas. This slowly destroyed the Earth and the animals on it.
After Global Warming, the environment is completely destroyed. The ice melted and the trees died along with a lot of the animals. Now, the humans are being impacted as well because they no longer have resources to help them live.
