GCSE Biology (9-1) - GCSE Biology - Deforestation & Land Use (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ *** WHAT'S COVERED *** 1. The importance and diverse human uses of land as a finite resource. * Examples of land use: building towns and cities, quarrying, farming, and waste disposal. * Consequences of human land use: reduced land availability for other organisms and environmental damage. 2. Deforestation: the process of clearing forests. * Primary reasons: clearing land for agriculture (cattle ranching, crop cultivation including rice and biofuels), and logging for timber and fuel. * Key environmental impacts: reduction in photosynthesis leading to increased atmospheric CO2, release of stored carbon from burning forests, and destruction of habitats resulting in biodiversity loss. 3. Peat Bog Destruction: threats to valuable ecosystems. * Formation and ecological role of peat bogs: acidic, waterlogged conditions leading to peat formation which stores significant amounts of carbon. * Reasons for destruction: drainage for agriculture and extraction of peat for fuel or garden compost. * Environmental consequences: release of stored carbon dioxide upon drainage and decomposition, and loss of unique habitats leading to reduced biodiversity and potential species extinction. *** CHAPTERS *** 0:00 Introduction 0:52 What is Deforestation 1:44 3 Problems of Deforestation 2:58 Peat Bogs 3:47 Destruction of Peat Bogs *** PLAYLISTS *** https://youtube.com/playlist?list=PLidqqIGKox7XPh1QacLRiKto_UlnRIEVh&si=orIUwL3o2jOoiYjT https://youtube.com/playlist?list=PLidqqIGKox7X5UFT-expKIuR-i-BN3Q1g&si=DcihOwUkd9oWbbdp https://youtube.com/playlist?list=PLidqqIGKox7WeOKVGHxcd69kKqtwrKl8W&si=Y8MsO-FK948jnxpS https://youtube.com/playlist?list=PLidqqIGKox7UVC-8WC9djoeBzwxPeXph7&si=-7i5Iq7yOeJrhtu6 https://youtube.com/playlist?list=PLidqqIGKox7VKJD2WxRhoKaI6JGLVean8&si=NH_Q1ujhVgACM2FU #GCSE #Biology #study #revision #school #exam #AQA #OCR #Edexcel #IGCSE
