Green plants remove carbon dioxide from the atmosphere and generate the oxygen required for life. Green plants are also a good source of food and protection.
How are plants beneficial to humans?
Plants maintain the atmosphere. They produce oxygen and absorb carbon dioxide during photosynthesis. Plants provide many products for human use, such as firewood, timber, fibers, medicines, dyes, pesticides, oils, and rubber. Plants create habitats for many organisms.
What are advantages of trees?
Trees give off oxygen that we need to breathe. Trees reduce the amount of storm water runoff, which reduces erosion and pollution in our waterways and may reduce the effects of flooding. Many species of wildlife depend on trees for habitat. Trees provide food, protection, and homes for many birds and mammals.
How many trees are on earth right now?
3.04 trillion trees
How many trees are cut each day?
2.47 million trees
What will happen if all trees are cut down?
With no trees, the land will heat up and dry out and the dead wood will inevitably result in enormous wildfires. This will fill the sky with soot that blocks out the Sun, causing failed harvests for several years and leading to worldwide famine.
