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 objectives of conservation biologists are to understand how humans affect biodiversity and to provide potential solutions that benefit both humans and non-human species. It is understood in this field that there are underlying fields of biology that could readily help to have a better understanding and contribute to conservation of ...
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 ...
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]
Therefore, humans should increase biodiversity in human-dominated landscapes. By managing for biodiversity in ways that do not decrease human utility of the system, it is a "win-win" situation for both human use and native biodiversity. The science is based in the ecological foundation of human land-use trends and species-area relationships.
The Millennium Ecosystem Assessment (MA) is a major assessment of the human impact on the environment, called for by the United Nations Secretary-General Kofi Annan in 2000, launched in 2001 and published in 2005 with more than $14 million of grants. It popularized the term ecosystem services, the benefits gained by humans from ecosystems.
Human–wildlife conflict has been defined by the World Wide Fund for Nature (WWF) in 2004 as "any interaction between humans and wildlife that results in negative impacts of human social, economic or cultural life, on the conservation of wildlife populations, or on the environment". [6]
Environment destruction caused by humans is a global, ongoing problem. [4] Water pollution also cause problems to marine life. [5] Most scholars think that the project peak global world population of between 9-10 billion people, could live sustainably within the earth's ecosystems if human society worked to live sustainably within planetary ...
