Our world has many environmental issues. These issues impact the environment, and all other areas in which humans inhabit. Ecosystems all over the world are being devastated, causing a shift in the equilibrium of our wilderness and the atmosphere. Biodiversity in our worldly community of animals and humans is vastly being affected. They might not realize it but everything on earth is directly related. There are a handful of countries that are industrial societies, one of them being the United States. There is enough trash in a landfill to go to the moon, there are an astonishing amount of pollutants in the air that human society breaths, migration patterns of species are being affected by climate change and many species are on the verge of extinction. An interesting theory is the “chaos theory”. This theory suggests that ecosystems can be very sensitive to little changes in the environment. There is a lot of evidence to prove this true, and there should be a conservation policy that prevents much change to the developing ecosystems. The risk assessment is incredibly high this day in age where society has a lot to lose, but the human population needs to become more malleable, and bend with new policies to make the world better, and preserve what mother earth gave. There are very many environmental issues, all are related in one way or another to humans and how they treat they’re land.
The popularity of wood stoves has risen, and so has the deforestation process. When there are no forests in an area, like a field or pasture, the animals graze the land until there is no hope for the plants. This is the desertification process. Once the land is like a desert, it can be like an all year drought season. When the land is arid and dry it makes the top level of the soil horizon more prone to erosion. Marine life are least affected by desertification, obviously, but other habitats like wetlands can be. Habitat destruction is a major environmental issue. Once the trees and other plants have been withered away and destroyed, either by human cause or by natural causes such as leaching, the micronutrients can be killed. Life, any life at all, needs nutrients to survive; otherwise the life forms suffer from malnutrition. Once an area has become desert, it disrupts the food chain of the area, and can cause famine for a hunter-gatherer society. Cash crops could still be grown in the area, but only with some help. The crops would need some sort of irrigation system, like drip irrigation, which uses a tube to deliver small amounts of water to the roots of the plants. Other people would use the area for different purposes, such as government agencies dumping radioactive wastes on the land. This could be a limiting factor for the area to ever get life again.
The biomedical revolution has made a huge difference when it comes to how the environment can affect the human race. There hopefully will be no more cases of the bubonic plague thanks to this revolution. Other diseases that can be cause by environmental factors cannot be as easily cured like cancer, or lung diseases, such as emphysema, that are caused by the air pollution in the cities. As the human population grows the germ theory of disease grows and becomes an issue. If a pathogen was to come into contact with a popular artesian well or aquifer or if the pathogen was to be deep-well injected, or come into contact with a popularly eaten carnivore or autotroph, it can be spread to most of the human population. This is possible because the demand for food is high, an obvious fact since everyone needs to eat food to survive. The consumer(s) eats the contaminated product. Alpha particles found in contaminated food can affect the growth rate of a population, and cause a mass extinction. Today in 2010, safety is a huge part of our food production, as well as other manufacturing companies throughout the United States. There are many steps and procedures companies must go through to make sure food is not holding any bacteria, like filtration, distillation, and sterilization.
