One thousand years ago, the Hawaiian Islands were nothing like that are today. The islands were populated with many different arrangements of indigenous animals and plants. Due to the immigration of humans and introduction of invasive species to Hawaii, the Islands changed dramatically.
The changes to the islands' environment began with the arrival of humans. The first humans to settle in Hawaii were the natives of Polenesia. It is said that these people stumbled across these islands and thus resulted in living there permanently. With the humans that went to Hawaii, also came invasive species. In most cases, when people come to a new or foreign land, they bring diseases with them, but since Hawaii was vacant of human life, disease was not brought with these migrants. The deadly diseases were brought to the islands by the European settlers.
Along with the humans, came other species. These attributed to the HIPPO factors of the islands'. Those that were brought along are known as invasive species. An example of an invasive specie of Hawaii are Fire ants. These ants rapidly destroyed the islands' vegetation, which in turn created a gap in the ecosystems' food webs, which ultimately wiped out the population of the native species and organisms. Another example used by Wilson are the pigs. The pigs rapidly over populated. Like the fire ants, the pigs also destroyed vegetation by uprooting and toppling tree ferns. This also creates a defect in the food web which will disturb all the living organisms in that ecosystem. The humans brought the pigs for food, and they did not know that they were subconsciously destroying the ecosystems and environments of the Hawaiian Islands. Sadly, today none of the original species of plants and animals are living in Hawaii, all of these organisms are invasive species.
Like many of the organisms that were affected by human invasion, the Vancouver Island Marmot is in dire need of help. It is endangered because of the rapid demand of ski slopes. Like the Marmots, panda bears in China are also being harmed by the demands of humans. As the world becomes more and more over populated, the habitats, ecosystems, and environment of organisms are at high risk. With the "need" for more industrialization and urbanization, humans tend to look past the huge damaging effects that are happening in the environment. This reinforces Wilson's bottle neck theory. That with the new technologies humans are destroying the environment in a permanent way.
Now that some people are beginning to recognize the damage that has taken place, they are advocating to save the animals. In order to save the organisms, we must in turn save their habitats. It is easier said than done. Trying to save just one animal, requires saving a whole food web chain, and the habitat. So it ends up being an entire ecosystem that needs to be saved. National parks must understand this concept of the area-species principle. In order to save the organisms efficiently, they must set aside an ample amount of land to let the ecosystem flourish.
Humans in this day and age control the future of the environment. With the amount of damage that has already taken place, it is going to take a tedious effort and hard work to replenish the environment. Although the damage is huge, it can be reversible, it just will take a serious amount of effort. The fait of the ecosystem lies in the hands of the humans.
