    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. Deforestation and climate change - Wikipedia

    en.wikipedia.org/wiki/Deforestation_and_climate...

    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.

  4. Deforestation - Wikipedia

    en.wikipedia.org/wiki/Deforestation

    Deforestation is defined as the conversion of forest to other land uses (regardless of whether it is human-induced). [14] Deforestation and forest area net change are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a given period. Net change, therefore, can be positive or ...

    Example of human caused habitat destruction likely capable of reversing if further disturbance is halted. Uganda. Natural vegetation along this coastal shoreline in North Carolina, US, is being used to reduce the effects of shoreline erosion while providing other benefits to the natural ecosystem and the human community.

  7. Wildlife conservation - Wikipedia

    en.wikipedia.org/wiki/Wildlife_conservation

    Key examples of human-induced habitat loss include deforestation, agricultural expansion, and urbanization. Habitat destruction and fragmentation can increase the vulnerability of wildlife populations by reducing the space and resources available to them and by increasing the likelihood of conflict with humans.

  8. Environmental issues in Africa - Wikipedia

    For example, in South Africa the mercury levels are severe due to coal combustion and gold mining. Mercury is absorbed from the air into the soil and water. [19] The soil allows the crops to absorb the mercury, which humans ingest. Animals eat the grass which has absorbed the mercury and again humans may ingest these animals.

    Instead, it impacts the whole country as low wages for high-risk mining worsen poverty rates, exacerbating negative social impacts such as conflict, higher crime rates, and child mortality. The effects of the exploitation of natural resources in the local community of a developing country are also exhibited in the impacts from the Ok Tedi Mine .
