Disadvantages of cutting down trees are:
It destroys animal habitats, decreases amount of oxygen in atmosphere, destroys plants that may be cures for diseasesTrees give us oxygen, it will be like cutting off oxygen supply.. The organisms that live around it will perish.It ruins the beauty.It will take away the shelter they provide for birds and other animalsIt will ruin life cyclesLess CO2 would be used up by trees = Less oxygen to be produced = Global warming speeds up = Many animals lose their homes; thus their lives = Our universe will become meaningless eventuallyWithout trees, there will be flooding as trees can soak up to 1,000 gallons a day. Without trees, there will be very little to soak up carbon dioxide and cleanse the air. Without trees all species depending on it would become extinct. Without trees, the climate would heat up faster as there will no natural "air-conditioning."An animal's habit can be lost and the animal may become extinct.
