Deforestation is responsible for as much as 30% greenhouse gas emissions. Trees are the biggest plants on our planet, they give us oxygen and keep our air clean by filtering out carbon and other pollutants from the atmosphere. Water cycles are also affected by deforestation as the content of water in the soil is reduced and this causes erosion, flooding and landslides. Trees are a significant part of our eco system extracting groundwater through their roots and releasing it into the atmosphere as they provide home to birds, insects and wildlife.
