Answer 1

I'm answering Q1: the major ways in which humans are damaging the environment is cutting down trees. trees are homes for other animals like birds and koalas and so much more I can't name. if you cut down a tree an animal loses its shelter, the animal doesn't have a shelter to stay, the animal dies, the animal dies we we have no food. Also trees are very much needed and very important for us humans. trees release oxygen when they use energy from sunlight to make glucose from carbon dioxide and water. also cutting trees adds carbon dioxide to the air and removes the ability to absorb existing carbon dioxide.
