    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. Anthropogenic biome - Wikipedia

    en.wikipedia.org/wiki/Anthropogenic_biome

    Anthropogenic biomes, also known as anthromes, human biomes or intensive land-use biome, describe the terrestrial biosphere in its contemporary, human-altered form using global ecosystem units defined by global patterns of sustained direct human interaction with ecosystems. Anthromes are generally composed of heterogeneous mosaics of different ...

    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]

  6. Habitat destruction - Wikipedia

    en.wikipedia.org/wiki/Habitat_destruction

    Probably the most profound impact that habitat destruction has on people is the loss of many valuable ecosystem services. Habitat destruction has altered nitrogen, phosphorus, sulfur, and carbon cycles , which has increased the frequency and severity of acid rain , algal blooms , and fish kills in rivers and oceans and contributed tremendously ...

    en.wikipedia.org/wiki/Effects_of_climate_change

    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.
