These regions contain a high number of plant and animal species and have been subjected to high levels of habitat destruction by human activity, leading to biodiversity loss. Deforestation and increased road-building in the Amazon Rainforest in Bolivia cause significant concern because of increased human encroachment upon wild areas, increased ...
Mass extinctions are characterized by the loss of at least 75% of species within a geologically short period of time (i.e., less than 2 million years). [18] [51] The Holocene extinction is also known as the "sixth extinction", as it is possibly the sixth mass extinction event, after the Ordovician–Silurian extinction events, the Late Devonian extinction, the Permian–Triassic extinction ...
Overconsumption describes a situation where a consumer overuses their available goods and services to where they can't, or don't want to, replenish or reuse them. [1] In microeconomics , this may be described as the point where the marginal cost of a consumer is greater than their marginal utility .
From the approximately 16 million square kilometers of tropical rainforest habitat that originally existed worldwide, less than 9 million square kilometers remain today. [7] The current rate of deforestation is 160,000 square kilometers per year, which equates to a loss of approximately 1% of original forest habitat each year.
On Marion Island in 2007, some 250–300 adult male subantarctic fur seals died in a two-week period. It was suggested, though not proven, that this gender-biased mortality was caused by Streptococcus sanguinis, a bacterium carried by the house mouse, an alien species accidentally introduced to the island in the 1800s.
From the beginning of 2023 through the end of September, the shelters have euthanized 2,536 dogs and 685 cats — that’s 10 times the number of animals euthanized during the same period in 2020 ...
But just because a food is popular doesn't mean it's always good for you - and there are about as many reasons to avoid the overconsumption of steak and other red meat as there are reasons to want ...
The IUCN Red List of Threatened Species is the best-known worldwide conservation status listing and ranking system. [ 8 ] Over 50% of the world's species are estimated to be at risk of extinction, [ 9 ] but the frontier between categories such as 'endangered', 'rare', or 'locally extinct' species is often difficult to draw given the general ...
