In recent times, many animals have disappeared because of humans. In the early 1900s, animals and plants were becoming extinct at the rate of 27,000 per year, according to Harvard University and William and Nellie White and The number of extinctions continues at a high rate in the two-firs...

Conservation - Recent Extinctions, Ecology, Biodiversity: To what extent has modern human activity increased extinction rates above the background rate? This discussion presents five well-known case histories of recent extinctions. From them, some genera
Declines in animal body sizes are widely reported and likely impact ecological interactions and ecosystem services. For harvested species subject to multiple stressors, limited understanding of the causes and consequences of size declines impedes predict
In the earlier mass extinctions… most of the plant diversity survived even though animal diversity was severely reduced. Now, for the first time ever, plant diversity too is declining sharply. — Edward O. Wilson In 'Edward O. Wilson: The Biological Diversity Crisis: A Challenge to Science'...
(两栖动物) are declining or have become extinct.Amphibians are animals,such as frogs,that live partly in water and partly on land.And they have been around for over 350million years.They have (41)survived three mass extinctions,including the extinction of the dinosaurs.Why are they dying out...
extinctions confined to large animals: small animals, plants, and insects disappeared, presumably not all through human consumption. Krech also contradicts Martin's exclusion of climatic change as an explanation by asserting that widespread climatic change did indeed occur at the end of the Pleistocene...
humans’___abilities allowed us to out-compete other species for resources, leading to many extinctions. AI systems could likewise deprive us of the resources we need for our survival. Less___, AI could displace humans economically and, through its powers of manipulation, politically. But wouldn...
