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.
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 ...
This is an accepted version of this page This is the latest accepted revision, reviewed on 10 February 2025. Gas in an atmosphere with certain absorption characteristics This article is about the physical properties of greenhouse gases. For how human activities are adding to greenhouse gases, see Greenhouse gas emissions. Greenhouse gases trap some of the heat that results when sunlight heats ...
The idea consists in providing financial compensations for the reduction of greenhouse gas (GHG) emissions from deforestation and forest degradation". [288] REDD can be seen as an alternative to the emissions trading system as in the latter, polluters must pay for permits for the right to emit certain pollutants (i.e. CO 2).
Per capita greenhouse gas emissions by country including land-use change, in the year 2000 according to World Resources Institute. Land-use change can be a factor in CO 2 (carbon dioxide) atmospheric concentration, and is thus a contributor to global climate change. [14]
Livestock produces the majority of greenhouse gas emissions from agriculture and demands around 30% of agricultural freshwater needs, while only supplying 18% of the global calorie intake. Animal-derived food plays a larger role in meeting human protein needs, yet is still a minority of supply at 39%, with crops providing the rest.
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.
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]
