Did you know that at the present rate of extinction 20% of the world’s animal species could be extinct in the next 30 years. A lot of this is because of changes to living and nonliving things and their habitats affecting the population of an ecosystem. Did you know that oil spills can even affect many worm species causing them to over populate. Also, Wolves aren’t the real bad guys in Yellowstone national park. My last point is about melting glaciers, and how their destruction is causing some of the worst damage to animal populations.
Oil spills cause both decrease and increase in animal populations. For example, the Axolotl Salamander, also known as The Mexican Walking Fish, and brine shrimp are aquatic animals, living in the gulf of mexico. When an oil spill happens in the gulf of mexico these species population’s reduce. This causes there predators to have less food, therefore killing a lot of their species. Also, worms ,the Axolotl Salamanders’ prey, population starts to increase until the population increase to the point of overpopulation. How overpopulation …show more content…
No. This is because Wolves actually benefit more species than they harm. This was shown in Yellowstone National Park. After 70 years without Yellowstone having any Wolf population, the Wolves were rewilded. What did this do for the ecosystems in Yellowstone? Well, what it did was overall Regenerate the land of Yellowstone. This occurred because throughout those 70 years without wolves, Deer population skyrocketed, resulting in destruction of fields and grass. As soon as the wolves killed off a lot of deer the grass and fields regrew. Also birds and possums and other rodents population increased do to the regenerated Yellowstone, giving them more places to build homes. Overall the change of adding Wolves back into the ecosystem benefited Yellowstone's ecosystem a lot. This goes to show not all changes in the ecosystem are
