These events are known as the 5 Mass Extinctions‚ and scientists believe we are now on the precipice of the sixth. Researchers say that humans are the only ones that are causing the sixth extinction. How are humans causing this? Habitat destruction‚ an ever growing population‚ agricultural production and air pollution are all contributing to the latest extinction. These activities are causing even more species to become extinct. The thought of the sixth extinction is scary‚ but we can still stop it

The Thylacine also known as the Tasmanian Tiger was a marsupial that’s now constantly debated on its extinction‚ here’s why. The Thylacine went extinct in the 1930’s but even since the sightings in Australia have been reported constantly. There are plenty of people who have claimed to have seen it‚ along with there are people who believe these sightings. My stance is that the animal is extinct considering most evidence or findings of it still being alive are usually badly taken pictures and when

plants‚ and animals‚ are creatures that are a part of the world. There are a lot of species that we don’t know due to endangerment. There are many animals that our kids and our grandkids are not going to know either because now they are in danger of extinction. Many animals are in danger because of us‚ just think about it. Every years‚ we as a human raze‚ are causing danger to many animals. There are several causes of endangered species: habitat destruction‚ introduction of exotic species‚ and overexploitation

Organisms Gray wolves were once free to roam across Northern America‚ but this was before people hunted‚ trapped‚ and poisoned them. The drastic reduction of the Gray wolves in Northern America was a devastating blow to the ecosystem‚ but their extinction marked a critical loss to the diversity of the ecosystem. Many scientists agreed that reintroducing the Gray wolves was the best solution to restore the diversity of the ecosystem (Raven‚ 2009). While this recommendation was adopted some decades

Saving the World Habitat loss isn’t only hurting our plant and animals around the world. Humans are also a part of the life cycle and depend on all of these damaged natural resources to maintain the life we live every day. Properly functioning natural systems give us the ability to breath‚ create safe food and drinking water and provide us with everything we need to survive. Each species plays an important role in its ecosystem. Habitat loss and degradation is one of the biggest threats to animals

Rafael Christian L. Bojador Environmental Science CAS-01-401P “Is the world overpopulated?” Facts: Overpopulation is a generally undesirable condition where an organism’s numbers exceed the current carrying capacity of its habitat. The term often refers to the relationship between the human population and its environment‚ the Earth‚] or smaller geographical areas such as countries. Overpopulation can result from an increase in births‚ a decline in mortality rates‚ an increase in immigration

The pace of the languages extinctions are faster than the extinction of flora and fauna. The proof is in the last 5 centuries‚ an estimated half of the world’s languages have become extinct; but now language does not even need much longer period to become extinct; a century and it will be done.

What is going to happen to the wild animals if we continue eliminating them at this rate? They will become victims of animal endangerment. What is animal endangerment? Endangerment of an animal means that the animal species is close to extinction. When discussing the causes of endangerment‚ it is important to under stand that individual species are not the only factors involved in this dilemma. Although some measures are being taken to help specific causes of endangerment‚ the universal

In recent years‚ we have seen the ecosystem flourish due to a successful reintroduction of wolves into Yellowstone National Park. We have seen a steady decrease in elk population‚ which in turn helped create a successful trophic cascade. Looking at graphs we can see that the wolf reintroduction has done its job‚ and we see a more than 50% decrease in population of elk. But what could happen if the wolf population doubled. We could see a total extermination of elk from Yellowstone and a decrease in
