Endangered Animals. Human beings‚ 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

ABSTRACT An ecosystem is a very important part of our natural world. Everything relates to nature in one way or another. In turn‚ should be treated with respect and should be not tampered from its original state. With animal annihilation and extinction aside one large issue that comes to mind dealing with ecosystem imbalance is invasive species. Most invasive species do not add or diminish from there new invasive ecosystem but sometimes they can cause a devastating effect on things such as population

Primary Post “The surrogate species approach is the most cost effective means for establishing national and global conservation priorities.” Conservationists are challenged with the problem of protecting a range of species at minimal costs. As such conservationists have to prioritize to help those in most need of assistance or trouble (Myers et al. 2000). Therefore‚ many conservationists have adopted the surrogate species approach as a shortcut to aid with the conservation priority decision (Caro

of new species. Since the development of modern genetics in the 1940s‚ evolution has been defined more specifically as a change in the frequency of alleles in a population from one generation to the next. Darwin ’s theory of evolution describes the descent of all living organisms from a common ancestor. Natural Selection is the principal mechanism that causes evolution. In common parlance the word "evolution" is often used as a shorthand for both the modern theory that all extant species share a

was passed in May of 2008 to protect the polar bear species from extinction by adding them to the endangered list. This should be a wake-up call to every individual living on the planet Earth as it is time to take responsibility for our actions and start making serious changes. Continued decrease of sea ice levels is expected in the future which affects the entire span of polar bears which reclassifies their status as threatened and endangered. The initial process began with a 12-Month Petition

grasses as well as invasive grasses. Native and Invasive species play a big role in our ecosystem. Native species make it so we don’t have to use as many fertilizers‚ use less water‚ keep the air around you cleaner‚ provide shelter and food for wildlife etc. Invasive grass species are bad because for one they are obviously not native to the area and can colonize habitats and exclude the native plants. Did you know a Dandelion is an invasive species? Well it is it from Europe but can be commonly found

things come to mind such as climate change‚ water pollution‚ species loss‚ or deforestation. Yet so many other problems get overlooked because they are unrecognizable or do not get as much media coverage. One of these issues is the threat of invasive species. Some people will walk past them every day without even realizing it. After all why would anyone question something that looks just like another plant‚ insect‚ or animal. Invasive species are not as in your face as pollution or deforestation‚ but

From fauna like the Burmese python‚ to flora like the Brazilian peppertree‚ Florida has quite an extensive variety‚ as well as history of invasive species. Many may not even appear to be invasive‚ as we’ve grown so accustomed to seeing them. The phrase “invasive species” is defined by the National Invasive Species Council as “. . .a species that is non-native to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental harm or harm to human health”
