Trees provide us with oxygen, wood for furniture, paper, pencils and such. Many fruits also grow on trees.
Trees are vital to life for humans and animals. Specifically, trees produce the oxygen that all living creatures need to survive.
solar energy do not do anything for humans
water sustains all organic life humans are 98% water
Trees take carbon dioxide and turn it into oxygen that creatures breath including humans.
Yes by taking there homes by cutting down trees for paper
"Save trees, save life." Bumper Sticker: "If you can breathe while reading this, thank a tree." (printed on recycled paper)
Yes, ficus trees are not poisonous to humans.
Carbon is important to humans believe it or not...trees need carbon dioxide to survive and they emit oxygen which we need to survive...connect the dots
Most of the endangered trees are used for things that humans don't really need life a coffe table, carvings etc. Some are useful for humans like a wooden chair, desk and etc.
Not only do trees support humans, they support animals too. In a complicated sense we support the trees as well because they take in our carbon dioxide. Therefore, if there werent any trees giving off oxygen, there would be no humans and if there is no humans no carbon dioxide for the plants.
ok let me bring you through the cycle of life: TREES TAKE IN CARBON DIOXIDE TREES RELEASE OXYGEN HUMANS BREATH OXYGEN AND RELEASE CARBON DIOXIDE Therefor more oxygen = more life / saving lifes
trees are cut for development.
