Some reasons to save trees (Environment is the base)?

Question

Can someone give me some strong reasons why we should save trees/environment? I need for 8th grade Speech

Answer 1

trees are our biggest givers of oxygen next to the ocean plant life and also trees hold the soils so farmers can grow their crops they gave us fruit,  medicines ,flowers the world with out trees would be a very barren place to live, the more trees in the rain forest the more rain, with out rain all plant life would die.

Answer 2

Trees make oxygen...we need oxygen...most life on earth would die without it.

Many species of animals only live in certain trees without the trees whole ecosystems would fail.

No more trees mean no more wood bats for baseball...
