    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, [ 211 ] but coal-fired power is the dirtiest.

  3. Rainforest - Wikipedia

    en.wikipedia.org/wiki/Rainforest

    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]

  4. Deforestation and climate change - Wikipedia

    Other effect of deforestation in the Amazon rainforest is seen through the greater amount of carbon dioxide emission. The Amazon rainforest absorbs one-fourth of the carbon dioxide emissions on Earth, however, the amount of CO 2 absorbed today decreases by 30% than it was in the 1990s due to deforestation. [35]

  5. Biome - Wikipedia

    en.wikipedia.org/wiki/Biome

    Humans have altered global patterns of biodiversity and ecosystem processes. As a result, vegetation forms predicted by conventional biome systems can no longer be observed across much of Earth's land surface as they have been replaced by crops and rangelands or cities.

  6. Deforestation - Wikipedia

    en.wikipedia.org/wiki/Deforestation

    Rainforests once covered 14% of the earth's land surface; now they cover a mere 6% and experts estimate that the last remaining rainforests could be consumed in less than 40 years. [294] Small scale deforestation was practiced by some societies for tens of thousands of years before the beginnings of civilization. [295]

    Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...

  8. Effects of climate change on biomes - Wikipedia

    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.

  9. Effects of climate change on the tropics - Wikipedia

    en.wikipedia.org/wiki/Effects_of_climate_change...

    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.
