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.
The issues facing the earth’s environment has given scientists the inspiration and desire to create new methods and technologies to deal with the issues. This is known as the Green Revolution. Some methods are extremely easy, and can be done by anybody who has a back yard. Compost piles are an easy way to help the planet; they reduce the amount of matter going into the landfills, and make good fertilizer for mother earth. Recycling is important, and preached pretty much everywhere. Just by switching incandescent lights to fluorescent lights can reduce the amount of energy being used. Traditional farming methods have changed with the rest of the world. Farmers are using more “green” methods of making a living, such as integrated pest management, and strip cropping. More technological methods have been developed by scientists, their hypothesis being that the new technologies will be less harmful to the o-zone layer, which is the experimental variable. The control is society doing what they normally do. The active solar heating systems have been put through the scientific process and have proven to be a success. It uses the energy from the sun to produce energy that society can use to do everyday things. Hydroelectric power uses the natural and abundant resources we have here on the earth as well, and biomass fuel is a healthier alternative to fossil fuel, which isn’t a renewable resource. Fossil fuels create harmful emissions that are put into the air, these emissions are known as greenhouse gases, and they cause a lot of damage to the atmosphere (the greenhouse effect).
Everyday we are faced with concerns for our environment. But yet, there are so many other issues in this world that need to be taken care of as well. There are families starving all over the world with no places to live (this is even on American soil). People are faced with war, famine, poverty, but the biggest thing is these environmental issues. These issues contribute to the downfall of our beautiful planet, and once our planet is gone, we will not have to worry about the blight that effected most crops, or we won’t have genocide. No matter what is happening between humans, any conflicts at all, we have to remember that we are not US citizens or Australian citizens, we are world citizens, and we need to keep our earth alive and thriving, and the only way to do so is through education and awareness.
