Causes For The Quaternary Extinction Event The quaternary extinction event happened about 10‚000–40‚000 years ago. This even is when megafaunal animals went extinct. This event saw the extinction of more than 178 species. Megafaunals are defined as “A term generally used to refer to the largest animals present within an ecosystem‚ most often used with respect to the array of large-bodied species which suffered extinction during the Quaternary. A strict definition refers to animal species weighing

pollution. When endangered species encounter these issues they die and eventually become extinct. An example of overhunting is how sailors overhunt musk oxen and caribou for their fur and body meat. The fur gets used for clothing and the sailors eat the body meat. The musk ox is nearly extinct due to overhunting. When you over hunt a whole species‚ that species may go completely extinct‚ if they go extinct then that messes up the whole food chain/web. The excessive hunting of the polar bears hides

and just only think that they only make honey and pollinate flowers. Bees do a lot more than just make honey‚ pollinate flowers or sting living things for defensive purposes. Bees play a big part in our food supply and the environment‚ if they go extinct then we lose a lot of food and the ecosystem will be out of balance. Bees do a lot for the ecosystem‚ the main thing that they do is pollinate. “Pollination is essentially plant reproduction. Without help from animal pollinators‚ our

chance of becoming extinct. Most tigers are being held in captivity to keep them reproducing‚ there is one type of tiger that no longer exists in the wild but is held in captivity. Humans now control the fate of the tiger‚ their choices will determine whether it survives or becomes extinct (Wikipedia). If humans could make hunting tigers illegal for a while and let them reproduce‚ it would help the tiger stay in existence. Three out of the eight species of tigers are already extinct‚ which are the

that lead to animal extinction are irresponsible human’s hands that destroyed animal’s habitat by deforestation‚ illegal wildlife trades and climate change. Deforestation is the main causes that lead animal species loss their habitat and become extinct. If people loss their house‚ they will not have any shelter and live without protection. This situation also happened to the animal species in this world. “Deforestation is a great way to eliminate the terrestrial species in this world” (Greenwell

Geologists classify volcanoes into three distinct groups: dormant‚ extinct‚ and active. Active volcanoes have erupted recently and are expected to continue to erupt again soon. The Smithsonian Global Volcanism Program defines an active volcano as having erupted within the last 10‚000 years. A volcano finally goes extinct when there’s no lava supply in the magma chamber beneath the volcano. There are approximately 1‚500 active volcanoes in the world today and 75 percent of them are located in the

many times poachers kill animals until they become greatly endangered or extinct. This causes some problems in the ecosystems where these animals live. If one animal goes extinct‚ this means less food for the animal that used to eat it as prey. One animal that went extinct is the Western Black Rhinoceros and “In 2011 the International Union for the Conservation of Nature (IUNC) declared the Western Black Rhinoceros extinct.” This is one example of how poachers can kill one
