In this video, we explore what deforestation means, why forests are cut down, and how it affects our planet. From building houses to farming, we look at the main causes of cutting trees. We also explain the harmful effects: Rise in temperature and pollution Increase in carbon dioxide leading to global warming Reduced rainfall and more chances of floods Soil erosion and loss of fertility, causing desertification Shankar Nair video https://cdn.kastatic.org/googleusercontent/ZCdwTudJg6e6n-P2gsaUborP4izvMsGo71pvEVlX9dNYWcLXcP7VHkWpn2grt4TUP1KoJLQP9NswyHBuBLSFTBw Deforestation Why is deforestation a big problem?
