Persuasive Essay On Overpopulation

The first example of human manipulation of changes within the biosphere is through expansion. The rapid growth of the population has led to expansion in development; the need for more space is causing strain on other living organisms such as plants and animals. Human procurement of forest, grass, and wetlands has weighed on the animal population heavily. As a result of this domination, animals have lost areas they use to thrive in, causing migration and in more serious cases extinction. Animals are a prevalent source of protein for humans, and when a species is threatened by extinction, it not only disrupts the balance of the ecosystem, but it also disrupts the food chain. The more resources that are required to sustain human life, the bigger the need to migrate to surrounding areas in a short period of time (Haines).

“The Wreck of Time,” written by Annie Dillard, illustrates societies battle with population. Dillard emphasizes the disasters that savage our world. According to the author, “ By moderate figures, the dead outnumber us about fourteen to one. The dead will always outnumber the living.” (Dillard 168) The amount of natural or man-made catastrophes do not affect the population as much as we claim. Dillards opinions are supported with facts throughout her essay, but readers are still left to question, why is our world considered to be overpopulated? Perhaps it is time for our society to consider Earth is not overpopulated in terms of people, but in resources. In addition, humans are struggling to grasp that other ecosystems are also being affected. With the introduction of Darwinism (the theory of evolution, by natural selections), humans are programed with the mentality of “survival of the fittest” forcing our humanity to evolve. Although evolution proved to be beneficial, as our immune system and way of life improved, we sacrificed our natural resources along the way. The problem with our society is not the lack of knowledge, but the ignorance and selfishness within our society. Overpopulation, threatened by the lack of resources, intimidates humans to disrupt biodiversity as we know it. (1) Man-made changes jeopardize our biodiversity. (2) As a result, the Earth’s resources are being depleted due to rapid consumption. (3) Even though we lack resources,

The last mechanism of extinction is habitat fragmentation. This is the process by which habitat loss results in the division of large, continuous habitats into smaller, more isolated remnants. A perfect example of this is the Sumatran Rhino that was such a big population that was considered a pest until their habitat was fragmented. This decreased their population and when put in captive breeding they decreased even

Transition: Now that we know what a problem animal overpopulation is, let’s talk about how we can help to solve this issue.

The scale and pace of change is dramatic; for example, the extinction of species is occurring at around 100-fold pre-human rates4. The population sizes of vertebrate species have, on average, declined by half over the last 45 years5. More than 2.3 million km2 of primary forest has been felled since 20006. About

Say a frog eats a caterpillar, then a snake eats the frog, then finally a owl eats the snake. This is just a simple food chain but something called biodiversity, which means that’s there is a variety of things a that one animal can eat. An owl cant only eat a snake it could eat the frog or something smaller like a worm. This keeps form one species dying out completely, which would cause multiple species to die out. When someone releases a pet into the wild they are causing a disturbance into the wild habitat. When a python is released into a place full of crocodiles these two will start competing for food which would cause all of the lower species to start lowing in numbers faster until they become extinct which would then make the snakes and the crocodile die off too. If this keeps on happening the eventually every animal would die off!

-Wolves helped to maintain exploding number of deer and elk that were hurting biodiversity in the park.

It is our actions that have directly, and indirectly, caused such environmental destruction; now it is us that must help save them. As John Sawhill said, "In the end, our society will be defined not by what we create, but what we refuse to destroy." We are their only hope; future generations of animals and mankind alike are depending on us.

Extinction: Most species become extinct because they can’t cope with the environmental change, and also because of introduced species that turned into competitors for

When herbivorous species such as white-tailed deer and elks are the main predators in a habitat, they create an imbalance in the habitat, and force other species in the habitat to go extinct. Natural predation also has a stronger impact in stabilizing or reducing the population of white-tailed deer than human hunting alone. One of the main reasons for the overpopulation of the deer was the extinction of their predators. Every animal in the food web is highly important in keeping the balance in the ecosystem. Yellowstone National Park was a great example of how every species support the

No matter how many people do claim overpopulation is not a relevant issue, it very much is because of the simple fact that starvation and pollution are very real and existing issues that are ultimately offset by overpopulation. In an article titled “Overpopulation Is Not the Problem,” author Erle C. Ellis uses the analogy “Like bacteria in a petri dish, our exploding numbers are reaching the limits of a finite planet, with dire consequences,” to argue that overpopulation is not a problem by stating the opposing claim. “We are nothing like bacteria in a petri dish,” Mr. Ellis solemnly asserts, “...these claims demonstrate a profound misunderstanding of the ecology of human systems. The conditions that sustain humanity are not natural and never have been. Since prehistory, human populations have used technologies and engineered ecosystems to sustain

The ecological conditions might have changed quickly and the species was not able to adapt to those conditions, which eventually lead the species to go extinct.

Ecosystems: when they are taken out there predators will have nothing more to eat then they will start dying off and it will keep going like a chain reaction.

Since the beginning of life itself, some species have lived and prospered while other species have gone extinct never to be seen again by mankind. Because of this, some would claim that extinction is natural and not significantly problematic to the world that we live in. Others, however, understand that due to climate change, habitat loss, and poaching, more and more species are becoming endangered which leads to a chain reaction that can be devastating to ecosystems. Species such as the Chinook salmon, gorillas, tropical sharks, and polar bears are all directly affected by climate change, species such as northern spotted owls, Sumatran tigers, and lemurs are greatly harmed due to habitat loss, and species such as the sea turtle, Javan rhinoceros, African elephant, and the Red-Fronted Macaw are all affected by poaching driving them all closer and closer to becoming extinct.

Habitat destruction, deforestation, ozone depletion, global warming, and poaching. These actions and ecological happenings are creating a world where animals are going extinct at rapid rates. Our world is on the brink of what scientists believe is the sixth mass extinction. Unlike the five previous mass extinction, the latest one killing a majority of the dinosaurs, the main causes for this current extinction are anthropogenic reasons, not natural events.
