Earth is the only planet on which life is possible. We don't have a Planet B to move to. This makes saving the Earth and our lives even more serious. If we don't act hard now, we will miss the opportunity to see our future generations flourish forever. All must come together for the same purpose because we are inhabitants of this planet first and everything else second. Since all human activities affect the lives of other organisms, humans need to take action to protect the earth and its resources. A little effort will go a long way in everyone. Every action will make a difference.
