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 .
Mountains cover approximately 25 percent of earth's surface and provide a home to more than one-tenth of global human population. Changes in global climate pose a number of potential risks to mountain habitats. [13] Climate change can adversely affect both alpine tundra and montane grasslands and shrublands.
Climate change effects on tropical regions includes changes in marine ecosystems, human livelihoods, biodiversity, degradation of tropical rainforests and effects the environmental stability in these areas. Climate change is characterized by alterations in temperature, precipitation patterns, and extreme weather events.
These impacts can be split into operational impacts (fuel sourcing, global atmospheric and localized pollution) and construction impacts (manufacturing, installation, decommissioning, and disposal). All forms of electricity generation have some form of environmental impact, [ 210 ] but coal-fired power is the dirtiest.
Much of what remains of the world's rainforests is in the Amazon basin, where the Amazon Rainforest covers approximately 4 million square kilometres. [62] Some 80% of the deforestation of the Amazon can be attributed to cattle ranching, [63] as Brazil is the largest exporter of beef in the world. [64]
Tropical rainforests have been called the "jewels of the Earth" and the "world's largest pharmacy", because over one quarter of natural medicines have been discovered there. [2] Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. [3]
This has a profound ecological impact in that Colombia is extremely rich in biodiversity, with 10% of the world's species, making it the second most biologically diverse country on Earth. [ 151 ] In 2024, deforestation in Colombia's Amazon region has increased by 40% during the first quarter compared to the same period last year, according to a ...
It is important to conserve the rainforest because many resources for things we use everyday come from the rainforest, including rubber for tires and spices such as cinnamon and many other common items. [9] It is imperative to life on earth that the rainforest be conserved, as the trees take in carbon dioxide to provide oxygen.
