Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels. [4] [5] Greenhouse gases are emitted from deforestation during the burning of forest biomass and decomposition of remaining plant material and soil carbon.
Per capita CO 2 emissions from deforestation for food production Illegal "slash-and-burn" practice in Madagascar, 2010 Mean annual carbon loss from tropical deforestation. [149] Deforestation is a major contributor to climate change. [150] [151] [152] It is often cited as one of the major causes of the enhanced greenhouse effect.

Removals of greenhouse gases (specifically CO 2) from the atmosphere can be achieved through various forest management options, such as replanting degraded or deforested areas or enrichment planting, but also by letting forest land regenerate naturally. Care must be taken to differentiate between what is a purely ecological process of regrowth ...
When natural habitats are destroyed or natural resources are depleted, the environment is degraded; direct environmental degradation, such as deforestation, which is readily visible; this can be caused by more indirect process, such as the build up of plastic pollution over time or the buildup of greenhouse gases that causes tipping points in ...
Deforestation: When trees are cut down, the carbon they store is released into the atmosphere. Agriculture: This includes the production of food, feed, and fiber. Livestock production is a major source of methane, a greenhouse gas that is more potent than carbon dioxide.
Satellite photograph of deforestation in Bolivia.Originally dry tropical forest, the land is being cleared for soybean cultivation. [5]Biodiversity hotspots are chiefly tropical regions that feature high concentrations of endemic species and, when all hotspots are combined, may contain over half of the world's terrestrial species.

Carbon dioxide is a greenhouse gas, meaning it causes heat to get trapped in the atmosphere, rather than being released into space, raising the Earth's temperature – known as global warming. [303] Alongside greenhouse gas emissions the industry is also responsible for almost 35% of microplastic pollution in the oceans. [302]
