From the dawn of the dinosaur to modern day times, animals have been going extinct since their conception on Earth billions of years ago. With the ever overwhelming threat of climate change, many things in nature are at risk for becoming nonexistent. The phrase climate change possess a number of factors that contribute to environmental changes. “For climate change, relevant variables include temperature, precipitation and related variables, as well as atmospheric carbon dioxide levels, which exert important direct effects on organisms in both terrestrial and marine environments“ (Hannah 143). Over the past century, Earth’s average temperature has risen about one degree… temperatures may rise by an additional two to ten degrees by the end …show more content…
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. Estimates of extinction could reach up to 29%, depending upon the area and the biome the animal resides in. (Thomas et al. 146). When a particular area is not suitable for an animal’s habitat anymore, they often will migrate to an area that is more accommodating. In Lee Hannah’s book titled Saving a Million Species: Extinction Risk from Climate Change, he informs the public, “In general, it is clear that migration was an important coping mechanism for both mammal and plant taxa during global warming” (166). Often times, the only way for species to continue survival is through moving, but the creature often cannot do so. Due to rising temperatures, many species attempt to migrate northward, but the presences of humans is making this more difficult (Than n.p.). Animals look for a cooler environment to thrive in, but new developments from peoples and business retract this one method of survival. If animals cannot migrate or adapt, they possess the potential to become endangered species. The unsuitable environment often isolates animals, making them less genetically diverse, which could lead to certain species’ extinctions (Than n.p.). If the environment surrounding a species or community is inhospitable, the unsuccessful continuation of those animals appears
