The Causes Of A World Without Animals

The number of wild animals on Earth has halved in the past 40 years . Creatures across the land, rivers, and the seas are destroyed as humans killed them for food in unsuitable numbers, while polluting or destroying their habitats.

Without animals, humans would not be humans. Animals and humans co-exist together for a reason. Animals need humans, and humans need animals. There has been many stories of animals that change humans forever. One example is Temple Grandin, a high-functioning autistic woman whose life was extremely influenced by animals. She could see animals in ways others couldn't. She knew how to help the animals, and the animals helped her, too. Many people have stories similar to hers, and it's no surprise considering animals have always been such an important part of the development of the human

Animals have been there for us, even if we made the choice to leave them, they still decided to stay by our sides. Every new experience can make a person change, sometimes the change is negative and other times it is positive. Either way, there is no avoiding change. Animals are protective, understanding, and very helpful.

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!

Animals as well as humans have been around for an extended period of time showing that there obviously has been some sort of interactions between them throughout the years which may not have always been all the bad. They have been here for hundreds of thousands of years. They are our main source of comfort, happiness, joy, fun, and of course: food. Without animals we would not be at the point in life where we are today. Our next best source of food besides animals would have to be plants and who wants to eat plants all the time for every meal and only that? The treatment of those animals that we use as a food source and even the ones as pets is not always positive. Lobsters, a primary food source for the wealthy, are treated very poorly, for

Summarize: The result of one species extinction could potentially be fatal to the environment. In the animal kingdom, there is a food chain. Keystone animals, are the key ingredient to the food chain. When that keystone animals goes extinct, it sets off a chain reaction on the other animal’s food source. This causes one species to flourish and another to dwindle. The environment needs a healthy checks and balance system to keep each animal population under control (Stuart, 1990 ). Humans can cause the keystone animal to become extinct and therefore, responsible for rise and decline of other species, ultimately, throwing the food chain off balance.

Animals have benefitted us since the beginning of time. Today we use them for food and many other things. Before vehicles we used donkeys and horses to transport goods. We even used birds to deliver messages and now we use dogs to smell out drugs and even explosives. Without animals we would have a lot more problems that humans would not be able to solve. In ancient Egypt animals were worshiped.

In a summary, Kolbert explains the extinctions of a variety of different major animal species that became extinct. She also explains that if trends in the environment continue that the biggest extinction in history will occur soon. If global warming, deforestation, and glaciers continue to melt she says that more and more species will continue to become extinct. She explains how humans need to be more conservative and careful with what they’re doing to prevent extinction.

To begin with, habitats are shrinking. The article shrinking habitats from expert space states, “ A study shows that 70 percent of forest grounds are within a half-mile from the forest edge which is causing harmful effects”. These harmful effects are animals dying due to cars and getting lost from where their habitats are. These effects are boosting the rate of extinction.Also, in

As we lose more and more habitats, it could create a domino effect causing many other complications in the world's ecosystem.

can affect our chances of survival. Also, we rely on animals for food such as meat and

"We call them dumb animals, and so they are, for they cannot tell us how they feel, but they do not suffer less because they have no words” (Anna Sewell). There is undeniable evidence that animals are being affected by climate change. Even though the effects are difficult to measure, there are many different ways animals are being affected. With the loss of predator and prey species it affects the life cycles in the food chain. The earth’s climate change causes habitats such as snow, ice, or forest areas to alter, resulting in loss of habitat and food accessibility as well as causing extinction.

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.

It’s clear that a great extinction is coming from the evidence of the destruction of other species around us. The choices made by the human race have too often negatively affected the surrounding species. Tracy Wilson, the site director for HowStuffWorks.com, in an article for Animal Planet, states that

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.
