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

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

2- Chapter 1: Up to the Starting Line The arrival of human populations on Australia led to the extinction of large mammal populations. There are many possible predictions about what may have happened to the animals on that continent. One theory is that they were killed off by the first humans who arrived in Australia. In the text it claims‚ “Just as modern humans walked up to unafraid dodos and island seals and killed them‚ prehistoric humans presumably walked up to the unafraid moas and giant lemurs

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

If the population in any given area drops below 100 individuals‚ that population is just about guaranteed to be doomed‚ having entered an "Extinction vortex." Extended inbreeding leads to genetic deterioration‚ which then results in less reproductive males and females being born. The numbers begin to decline‚ and the cycle continues until the population completely dies out. Evidence of this genetic

into the everyday struggles some populations may have faced‚ with constant competition with Homo Sapiens for resources‚ and some engaging in cannibalism‚ the idea that the emergence of early modern humans was a majorly contributing factor to their extinction is a highly plausible one. Competitive edge regarding surviving/hunting on the part of early modern humans has accounted for the decline of Neanderthals’ during a span of thousands of years (Banks et. al 2008‚ 1). Early modern humans use of superior

According to the Fundamentals of Conservation Biology‚ conservation biology is concerned with “keeping the wave of species extinctions from becoming a flood” (Hunter‚ Jr.‚ & Gibbs‚ 2007). In order to do this‚ conservation biology targets the threatened species and devises ways to sustain the

Each and every animal on earth has as much right to be here as you‚ me‚ and of all humanity. Scientists have found a way to clone extinct species. The thought of that sounds amazing and really exciting‚ but think about it another way. If we bring back no longer existing animals‚ us humans will do what we do best‚ which is changing
