Deforestation Forests are vital for life, home to millions of species, they protect soil from erosion, produce oxygen, store carbon dioxide, and help control climate. Forests are also vital for us to live as they provide us with food, shelter and medicines as well as many other useful things. They also purify the air we breathe and water that we need to survive. Deforestation by humans is causing all of these necessary functions to be lessened, and hence damaging the atmosphere even further. How we work Do you want to know our tree planting and conservation process? Planting is only the beginning of our work, when you plant with us you are maintaining the tree in order to ensure its sustainability over years and reforest the right way.
