On monday, we talked about how the US and others have turned to protecting and saving nearly extinct creatures. The government has stepped in and created two lists of creatures that are either endangered, something that is at risk to be extinct in all or some of its natural range, and threatened, something that is at risk to become extinct. We have accelerated the extinction rate by 1000-10000 times faster than natures extinction rate would have. This needs to be changed because wild species are very important for many reasons: utilitarian uses, aesthetic beauty, moral reasons, and ecological reasons.
These creatures are some of the most noticeable endangered or threatened species across the globe. These creatures are vital parts of their ecosystems and are normally top tier predators that keep the other populations intact and not have them blow out of proportion.
Some ways that we have been trying to prevent these extinctions are treaties, or other pacts like CITES, or Convention on International Trade of Endangered Species. This prohibits international trade of any endangered or threatened species across international borders. Also The ESA or Endangered Species Act, protects creatures and the critical habitat from being harmed. These are only two of the many acts and treaties that have been enacted to protect endangered species.
Some of the main reasons that creatures go extinct prematurely are in a nice acronym HIPPO, this is the five highest reasons for premature extinction. 1) Habitat Destruction. 2) Invasive species 3) Human population growth 4)Pollution and 5) Over harvesting/poaching. This spells HIPPO.
An example of how a species succumbs to HIPPO are sharks all around the world, this video talks about how humans are depleting the sharks in such a short time period. Shark Alert! species struggles.
