The Coming Disaster: The Environment, Climate Change, And Human Influences

3086 words - 12 pages

Humans will not be able to survive the results of human activities due to land degradation, lack of water management skills, pollution, and increasing carbon footprints. In 1750, a revolution started globally. This revolution was called the Industrial Revolution; it changed agriculture, manufacturing, mining, transportation & technology forever. It has even changed lives economically and culturally, but most importantly, the great effects it has on the environment. “A glacier in the high Andes 5,200 meters above capital, Lima, where one of the main water supplying glaciers has shrunk by more than a kilometer over the last decade...Eskimo villagers are going hungry because global warming has changed the migration patterns of seals and walruses, an important part of the Eskimo diet,” (Humanity’s Future. 123-125). Land degradation plays a huge role in why human beings will not be able to remain on Earth forever. The US Global Change Research Program claims that land is one of the tools humans use to sustain life. Humans need land to plant food, and you can’t plant food if the land you are cultivating is no longer nutrient; it has to be arable land. Arable land is land suitable for growing crops. “The loss of arable land has been caused by a number of factors. Many or most of which are tied to human development. The primary causes are deforestation, over exploitation for fuel wood, over grazing, agriculture and industrialization.”(University of Michigan) The loss of land has been caused by a lot of things, mainly human activity; such as, deforestation, over exploitation, over grazing, and etc. Degraded land mainly comes from human development; from chopping down trees, to farming. Human development isn’t the only factor that ruins arable land; sometimes animals like cows ruin the land by over grazing. All in all, there is very little you can do to preserve land. In particular, deforestation is the biggest factor to contribute to land degradation, depending upon the region. In "WILL LIMITS OF THE EARTH'S RESOURCES CONTROL HUMAN NUMBERS?” David Pimentel says there are several factors that contribute to land degradation, and the biggest factor is deforestation.
“On the global basis, the soil degradation is caused by over grazing (35%), agriculture activities (28%), deforestation (30%), over exploitation of land to produce fuel wood (4%), and industrialization (4%).” 100% of what causes soil degradation is caused by humans and animals. 35% of the blame goes to the animals for over grazing, but the other 65% of the blame goes to the humans for agriculture activities and chopping down trees. Another example is, David Pimentel also states, “The bottom line on soil production is that it takes (on average) about 100 years to generate a millimeter of soil. This is about a human lifetime.” Although it is stated that animals contribute to land degradation, it’s only a small portion (35%). The main reason for loss of arable land is human development....
