Global warming is a very big threat to coral reefs, penguins and to the whole world. We are running out of time. We must act to together to protect our mother earth. People from all the nations must come together and plant as many trees as possible to stop climate change by removing carbon dioxide from the air, storing carbon in the trees and soil, and releasing oxygen into the atmosphere. This is the only path to see happy penguins, beautiful coral reefs and my happy world.
