All around the world, animals such as the black rhino, tigers, pandas, and so many others are facing extinction. Their numbers get lower everyday and yet little help seems to come to them. Part of the problem is that people do not seem to understand what losing just one species does to an ecosystem. Just the loss of one species could throw off the balance of an entire ecosystem and, if not replaceable, the entire ecosystem could collapse just from losing that one species. For example, if you were to take a tide pool ecosystem and remove starfish, all of the species who were connected to the starfish would become endangered and, slowly or quickly, mollusks would dominate the ecosystem with little or no other species left in the ecosystem. As interconnected as the world is today, the loss of one species would cause ripples around the world in places most people would not even think. For example, off the coast of North Carolina, scientists removed sharks from a certain area off the coast of the Outer Banks as part of an experiment. Because of the lack of sharks, barnacles began to dominate the area and the oyster population decreased dramatically. In fact, the population decreased so much that neighboring restaurants had to remove foods with any oyster or oyster by-product in them from their menus. The number one producer of oysters in the world is China, if something were to happen to the oysters or something were to happen to a species involved with the oysters and production were to decrease, the effects would be felt around the world. Restaurants would have to take oyster products off the menu, prices would go up, the ecosystems would suffer from the oysters and other affected species being unable to complete their niche. This, in turn, would cause other species, ecosystems, and economies to suffer. From there, it would become a whirlpool of issues. The good news is that there are already practices in progress to help these endangered animals. For example, natural parks such as the Theodore Roosevelt National Park and Bear Mountain State Park that have been created to protect and spread information about endangered animals. There have also been laws passed to limit hunting or prohibit the killing of these animals around the world. State of the art technology has been made in order to count the population of wild species, such drones that can also map deforestation and other dangers to animals. However, there are also steps that individuals can take. It can be something small, such as not littering, picking up litter, driving carefully so no animals are hit, minimizing use of pesticides, not buying things made from endangered animals, or just visiting a national park. Or, to do the most, individuals can start or join a clean-up crew for a certain habitat, make a backyard wildlife habitat, make a pollinator garden, report anything they see that harms endangered animals, email local politicians to pass laws that support endangered animals, or they can even join organizations and donate to protect endangered species. Communities can make a big difference just by setting environmentally-friendly guidelines, having a community park, having a community garden, and having fundraisers for endangered animals in the area. Countries can continue to pass laws and have organizations but it would also be helpful if more money were put into saving endangered species and if harsher punishments were given to people who violated the laws that protect endangered species. Even the loss of one species would have a huge effect and would cause damage all over the world. We must protect and help endangered species if we hope to have a positive future.
