People can take only so many fish from the sea or cut down so many acres of forests without permanently damaging ecosystems and threatening species. A dagger symbol (†) placed next to the name of a species or other taxon normally indicates its status as extinct. The leading cause of species extinction is habitat loss. Factors that cause extinction are inclusive but not limited to human activities, toxic pollution and climatic changes. There are five major causes of extinction: habitat loss, an introduced species, pollution, population growth, and overconsumption. Predation, completion and diseases can also cause extinction in animals. It poses a constant threat to terrestrial animals leading to a shortage of food and water. But these natural resources are limited. In this sense, extinction of animals takes place through natural selection. Climatic Heating and Cooling. This risk is an existential risk: a threat to the entire future of the species (and possible descendants). The biodiverse Earth can't keep up with the rapid changes in temperature and climate. 59 views Similarly to the previous point, we aren't doing nearly as much as we … Extinction: Biologically speaking, the termination of a species or group of taxon of organisms is considered extinction. Whenever something in the environment changes, it may cause one species to gain an advantage over another and cause its extinction. For instance, due to global warming, the water temperature in lakes and rivers is likely to increase. The Triassic-Jurassic Mass Extinction. 1. Agribusiness and homeowners are still applying pesticides, herbicides… Natural factors usually occur at a slower rate than human factors and therefore cause a lower extinction rate. It's happening now -- much faster than previously expected -- and it's entirely our fault, according to a new study. The advent of the environmental movement is generally attributed to a seminal book by Rachel Carson in 1962 called Silent Spring, silent to the dearth of songbirds caused by their poisoning by DDT, a pesticide sprayed ubiquitously at the time. They can adapt to a situation, somehow evolving a novel or more efficient way to live. Position in the food chain.
