For decades the world has been facing an ever increasing crisis in which the sustainability of our planet is not strong enough to support the expanding population. As our population grows, the emission of greenhouse gases into the atmosphere increases dramatically, causing a change in our climate that threatens the balance of nature. This essay will touch on just a few of the adverse impacts that a lack of sustainability in our world has had on the population of other species as well as our own.
In recent years, researchers and scientists have been concerned with the causes and effects that global warming has had on the environment. As excess greenhouse gases are emitted into the atmosphere, …show more content…
Clean drinking water is an irreplaceable resource that all humans rely on, and is one that many people around the world do not have access to. Due to the improper disposal procedures that are in place, water supplies are commonly polluted by industries, leading to the water becoming undrinkable. As more and more clean drinking water becomes polluted and deemed undrinkable, the need for new technology to filter water for safe consumption increases. As well as a filtration system, the need for advancements in ensuring the pollution of clean water supplies is taken care of has increased drastically. Without better protecting these water supplies, clean water will continue to become a rarer commodity that not everyone will have the privilege …show more content…
As the human population continues to increase, more and more animals’ habitats are threatened by expanding developments as well as deforestation caused by expanding cities and establishments. As well as this, changes in climate and the increase in water levels have also affected many marine species that are unable to adapt to the new conditions. The rate at which animals have become extinct in recent years has increased to a chilling amount, which is currently an approximated 200 species every day(Huffingtonpost.com, 2016). Not only are these species becoming extinct, but their absence in the ecosystems has caused a type of ripple effect, often called an ecological cascade, that is felt by all other species in that system. Whether that now extinct species was a food source of another species, or perhaps hunted another species and kept their population from increasing too much, each animal plays a vital role in its ecosystem. One example of this ripple effect is described in the short film “How Wolves Change Rivers,” which discusses the impact that the reintroduction of wolves to yellowstone national park has had on that ecosystem. Due to the lack of the wolves, the deer population had grown too large for the park to sustain as the vegetation was grazed to nearly nothing by the deer. By reintroducing the wolves, the deer population had lowered which in turn allowed
