Darwin's Theory Of Overpopulation

963 Words4 Pages

The struggle for existence is a widely known concept, and a term famously used by Charles Darwin in his writings. The struggle for existence refers to the many organisms on Earth and their constant competition with each other. One of the many ways life struggles with each other is overpopulation. Overpopulation is when one species grows rapidly or more than normal, over some short amount of time. In one of Darwin’s writings, we have to “... give it some advantage over a different set of competitors or enemies.” This means that in order for a species to be overpopulated it has to be favored or have an advantage over its competitors in some way. If one species is favored over all the other species in the same ecosystem, the population will increase rapidly. Every species and organism in the same ecosystem will interact and compete with each other. Darwin says that all organisms are “...all striving to increase, and all feeding on each other”. The growth of one species is determined by all of the other species living in the same ecosystem, acting as each other’s checks. An overpopulated species will affect the population of other species, however, the population should be checked soon. These checks can be factors such as not enough food or diseases and illnesses. An example of this would be if we say that the overpopulation of …show more content…

For example, now coyotes are in every state in the United States except Hawaii. The coyotes were able to spread without any consequences and are able to eat almost anything. Coyotes also have no natural predators, especially with the decrease in the wolf population. Without predators to keep the population in check, invasive species are allowed to grow without much competition. If an invasive species does not die off due to an unfamiliar environment the species will quickly become overpopulated, affecting every other species in that

    According to the World Wildlife Fund for Nature organization, the Mojave Desert ranks as the smallest desert among the four existing in America. Just like any other desert, it faces numerous threats to its wildlife and environment. An example includes the introduction of invasive species into their territory. The University of Nevada agrees that the invasive plant numbers are growing mainly from the results of human disturbance, which is a tremendous issue that can harm both plants and animals. Invasive species affect the diets of desert animals, their existence, and the populations of native plants.

    There are no drastic spikes in the populations of any one species, or drops in another. A large number of different species (a great biodiversity) is one indicator of an ecosystem’s health. Remarkably, biodiversity is not necessarily dependent upon the size of the ecosystem; some of the richest ecosystems in the world exist within narrow boundaries (sections of the Amazon rainforest, for example, and the Galapagos Islands). These ecosystems might be relatively small, but besides threat from destructive human behavior, they’re strong because of their biodiversity; each species is connected to the other in some way. If a healthy ecosystem is one that is home to many different species, mostly native to the area and all interdependent upon one another, what’s an example of an unhealthy ecosystem?
