Endangered Species

1. Endangered Species Angela Geng E7-1

2. What is an Endangered Species? • An Endangered species is a species of organisms that are in danger of becoming extinct because of decreasing numbers of them, a threatening environment for them, or too much predators. This is a serious real world problem because it can affect other living organisms. Some already extinct animals are the Dodo bird, Maryland Darter fish and Red Colobus Monkey.

3. How Does this Problem Affect Us? • Most of the animals are important to us because they are benefits to us and all species depend on one another. for our future and the food chain balance. The negatives is that some species might not have any prey and they might starve to death and cause diseases that can affect other species, and it damages the food chain. It harms us because it will affect humans if we catch that disease and spread it, and we will be living in an unhealthy environment. The other problems it may cause is extinction of other species and bad pollution for the environment like dirty water, bacteria in food and air.

4. Solutions • Some scientiststried to produce first stem cells from an endangered animal to hope for increasing population of that species but it did not work out very successfully. The scientists started with normal skin cells and produced first stem cells, and it made it poosible for a time to improve the population of some endangered species, and saving them from distinction. After noticing that the white Rhino had a low genetic diversity, they could produce unhealthy animals, so this solution was not the best solution for endangered animals.

5. Statistics There are 801 species that have been extinct and it has affected many other species. After some species died, other species did not have enough food and prey so they were sick and many died. It caused food chains to break a little and some animals did not have a stable environment to live in. This is a graph of Endangered Species Graphs.

6. Possible Solutions The main and most improtant solution is habitat protection for our endangered species because no species can live wthout a home. We need to find a stable environment for the species to live in and try to keep them safe and healthy. This is a successful solution because many species of organisms like the Aleutian Canada Goose, which was endangered in 1967 with only 790 birds, and now after protection from the Alaska Maritime National Wildlife Refuge’s creation in 1980 for a stable environment for the endangered species, there were more than 60,000 Aleutian Canada Goose in 2005. This was a very good solution because more than 110 species of animals have recovered today.

7. What Will be the Result if This Problem ISN’T solved soon? • If we do not take this world problem seriously then it will cause other species to be extinct and then at the end, humans might be in danger because of an polluted environment and surroundings of diseases. The food chain will collapse and break, and this will be bad for the future. So we should try to help and protect the endangered species for a better future, because all species depend on one another to survive.
