How the Lack of Sustainability Impacts our world
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,

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

    If predators are a problem in an area, lack habitat will be a deciding factor for survival. A lack of habitat will strand both fawns and fully grown deer to the open, where they are more likely to be taken by hunters and predators alike. Deer are most susceptible to predators in the fawning stage. In a study done during the non-fawning period, whitetail deer is found in only nine percent of coyote feces (Turner 5). The rest of the food consumed by the coyotes during this time was vegetation and smaller animals, such as voles.…

    Global warming has a number of impacts on people, oceans, temperature and ecosystems. There are more floods as well as droughts and this therefore puts many people at risk. The droughts result from the rise of temperatures as no plants are able to do well in those kinds of temperatures and climate. The sea level also rises as a result of global warming and greatly threatens people all over the world. According to scientists, the rise of sea levels is as a result of the melting of ice sheets due to global warming.…

    Climate change and global warming have always been a concern to humanity. Both have destroy homes and buildings, wasted billions of cash, and it had also altered people’s lifestyles in various ways. Global warming is the cause of the rising temperatures of the world, and that is where climate change takes place. Although awareness towards these continual changes have increased from place to place, the fact that it continues to grow means that the action against it is just not enough. Some of these concerns are carbon emission, massive loss of trees, and continual change of climate change.…

    The people living around Yellowstone National Park say the wolves are ranging out of the confines of the park and entering the nearby towns causing a concern for the safety of the residents that reside there. It’s understandable for families, especially with small children, to want the wolves removed because the potential harm the wolves could inflict on a small child. Also, cattle ranchers are worried about the wolves making an easy meal on all of the cattle. The cattle are the means of survival for some people living in Wyoming and to lose everything all to wolves can be a scary thought. Wolves are naturally aggressive animals but, being aggressive is how they have survived for thousands of years.…

    Our constant need to build and expand has put our presence in places where it doesn’t belong. When roads or dams are built, habitats are split up. When this occurs, animals get separated from their eggs or offspring and when a species is introduced to a new environment, they die off because the environment does not contain enough resources to withhold them. (Enzor, 2018) Also mentioned earlier, the emissions released to the ozone when trees are absent, harm it and contribute to global warming. Global warming alters many habitats and forces millions of species worldwide to adjust.…

    With impending temperature changes, scientist can already see how increasing degrees affect plant and animal species. These temperature changes create an inhospitable environment for many of the animals who cannot adapt, especially-large bodied mammals. In a 2003 study of 1,500 plant and animal species studied, 1,200 showed changes consistent with effects scientists would consider temperature-related. (Than n.p.). The world has the capability to appear completely different in the next fifty years, with many of the animals we know and love gradually disappearing.…

    Party hunters are not increasing the number of deer they are decreasing the numbers at a high and fast rate. If the party hunters at least set up a sanctuary for the deer and had a crop for them to survive in it would help the least amount for them. If party hunting was banned it would help regrow our declining numbers of deer in Minnesota. Party hunting needs to be outlawed because of the damage of habitat when the hunters ram through the country side. Party hunters ruin the habitat for deer and all the other animals.…

    Although Al Gore presents a well-constructed and very compelling argument on the effects of global warming, many have found his claims to be wrong and misinterpreted. For instance, he claims that as the earth tilts toward the sun the earth’s inhabitants absorb carbon dioxide. In the next season, the earth tilts away from sun allowing plants to release carbon dioxide creating an effect of inhaling and exhaling. This pattern shows the levels of carbon dioxide increase and decrease throughout the year. As years have passed, Al Gore shows how carbon dioxide levels continue to rise every year.…
