  2. Human impact on marine life - Wikipedia

    en.wikipedia.org/wiki/Human_impact_on_marine_life

    Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]

  3. UN Decade on Ecosystem Restoration - Wikipedia

    Human activities are affecting the capacity of ecosystems to provide these goods and services. [18] [19] Drivers of biodiversity loss and decline in ecosystem functioning include climate change, deforestation, desertification and land degradation, freshwater decline, overexploitation, stratospheric ozone depletion, and pollution.

    The Report examined the rate of decline in biodiversity and found that the adverse effects of human activities on the world's species is "unprecedented in human history": [14] one million species, including 40 percent of amphibians, almost a third of reef-building corals, more than a third of marine mammals, and 10 percent of all insects are ...

    The World Scientists' Warning to Humanity in 1992 begins with: "Human beings and the natural world are on a collision course". About 1,700 of the world's leading scientists, including most Nobel Prize laureates in the sciences, signed this warning letter. The letter mentions severe damage to the atmosphere, oceans, ecosystems, soil productivity ...

    English: This publication presents the first global assessment of biodiversity for food and agriculture worldwide, including plants, animals and microorganisms at genetic, species and ecosystem levels, present in and around crop, livestock, forest and aquatic production systems.

  7. Ecological effects of biodiversity - Wikipedia

    en.wikipedia.org/wiki/Ecological_effects_of...

    Beyond the value biodiversity has in regulating and stabilizing ecosystem processes, there are direct economic consequences of losing diversity in certain ecosystems and in the world as a whole. Losing species means losing potential foods, medicines, industrial products, and tourism, all of which have a direct economic effect on peoples lives. [6]

  8. Habitat destruction - Wikipedia

    en.wikipedia.org/wiki/Habitat_destruction

    The loss of biodiversity may not directly affect humans, but the indirect effects of losing many species as well as the diversity of ecosystems in general are enormous. When biodiversity is lost, the environment loses many species that perform valuable and unique roles in the ecosystem.

  9. Biodiversity loss - Wikipedia

    en.wikipedia.org/wiki/Biodiversity_loss

    Biodiversity loss has bad effects on the functioning of ecosystems. This in turn affects humans, [45] because affected ecosystems can no longer provide the same quality of ecosystem services, such as crop pollination, cleaning air and water, decomposing waste, and providing forest products as well as areas for recreation and tourism.
