  2. Human impact on the environment - Wikipedia

    en.wikipedia.org/wiki/Human_impact_on_the...

    As indicated by the I=PAT equation, environmental impact (I) or degradation is caused by the combination of an already very large and increasing human population (P), continually increasing economic growth or per capita affluence (A), and the application of resource-depleting and polluting technology (T).

  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 - 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 ]

  5. I = PAT - Wikipedia

    en.wikipedia.org/wiki/I_=_PAT

    I = (PAT) is the mathematical notation of a formula put forward to describe the impact of human activity on the environment. I = P × A × T. The expression equates human impact on the environment to a function of three factors: population (P), affluence (A) and technology (T). [1]

  6. Effects of climate change - Wikipedia

    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 ...

  7. Deforestation and climate change - Wikipedia

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

    [10] [11] The relationship between deforestation and climate change is one of a positive (amplifying) climate feedback. [12] The more trees that are removed equals larger effects of climate change which, in turn, results in the loss of more trees. [13] Forests cover 31% of the land area on Earth.

  8. Effects of climate change on the tropics - Wikipedia

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

    The involvement of community leaders, professionals, and local residents provided a rich source of knowledge on effective practices to combat the impacts of climate change on food security and livelihoods. This approach emphasizes the importance of local knowledge and community-based strategies in developing resilience to climate change. [10]

  9. Effects of climate change on biomes - Wikipedia

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

    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.
