The leaves on tree contains chloroplasts which can turn carbon dioxide into oxygen. And carbon dioxide is the metabolic waste produced by animals and also the byproduct of fuel burning. Too high concentration of carbon dioxide in the astomosphere can cause green house effect which make the earth warmer and insuitable for human to live on. And all animals live with oxygen. So trees are so important for the ecological balance for the earth.
