Anthropogenic Metabolism - Negative Effects of Anthropogenic Metabolism

Negative Effects of Anthropogenic Metabolism

In layman's terms, anthropogenic metabolism indicates the human impact on the world by the modern industrialized world. Much of these impacts include waste management, our ecological footprint, water footprints, and flow analysis (i.e., the rate at which we deplete the energy around us). Most anthropogenic metabolism happens in developed countries. According to Rosales, "Economic growth is at present the main cause of increased climate change, and climate change is a main mechanism of biodiversity loss; because of this, economic growth is a major catalyst of biodiversity loss."

A water footprint is the amount of water that each of us use in our daily lives. Most of the world's water is salt water which we cannot use in our food or water supplies. Therefore, the freshwater sources that were once plentiful are now being diminished due to anthropogenic metabolism of the growing population. The water footprint encompasses how much fresh water is needed for each consumer’s needs. According the J. Allan, "there is a huge impact of water use on stores of surface and groundwater and on flows to which water is returned after use. These impacts are shown to be particularly high for manufacturing industries. For example, that there are less than 10 economies worldwide that have a significant water surplus, but that these economies have successfully met, or have the potential to meet, the water deficits of the other 190 economies. Consumers enjoy the delusion of food and water security provided by virtual water trade.

In addition, the ecological footprint is a more economical and land-focused way of looking at human impact. Developed countries tend to have higher ecological footprints, which do not strictly correspond to a country's total population. According to research by Dias de Oliveira, Vaughan and Rykiel, "The Ecological an accounting tool based on two fundamental concepts, sustainability and carrying capacity. It makes it possible to estimate the resource consumption and waste assimilation requirements of a defined human population or economy sector in terms of corresponding productive land area.

One of the major cycles that humans can contribute to that cause a major impact on climate change is the nitrogen cycle. This comes from nitrogen fertilizers that us humans are using. Gruber and Galloway have researched, "The massive acceleration of the nitrogen cycle caused by the production and industrial use of artificial nitrogen fertilizers worldwide has led to a range of environmental problems. Most important is how the availability of nitrogen will affect the capacity of Earth's biosphere to continue absorbing carbon from the atmosphere and to thereby continue helping to mitigate climate change."

The carbon cycle is another major contributor to climate change primarily from anthropogenic metabolism. A few examples of how humans contribute to the carbon in the atmosphere is by burning fossil fuels, and deforestation. By taking a close look at the carbon cycle Peng, Thomas and Tian have discovered that, "It is recognized that human activities, such as fossil fuel burning, land-use change, and forest harvesting at a large scale, have resulted in the increase of greenhouse gases in the atmosphere since the onset of the industrial revolution. The increasing amounts of greenhouse gases, particularly CO2 in the atmosphere, is believed to have induced climate change and global warming.

There are many things that are going to be affected by climate change instead of just humans, the animals are going to suffer as well. There is a forecast for extinctions of species because of their habitats being affected. An example of this is marine animals. There are major impacts on the marine systems as a result of anthropogenic metabolism, according to Blaustein, the dramatic findings indicate that "every square kilometer affected by some anthropogenic driver of ecological change".

The negative effects of anthropogenic metabolism are seen through the water footprint, ecological footprint, carbon cycle, the nitrogen cycle, studies on the marine ecosystem that show major impacts by humans and developed countries which include more industries thus more anthropogenic metabolism.

Famous quotes containing the words negative, effects and/or metabolism:

    A negative judgment gives you more satisfaction than praise, provided it smacks of jealousy.
    Jean Baudrillard (b. 1929)

    If I had any doubts at all about the justice of my dislike for Shakespeare, that doubt vanished completely. What a crude, immoral, vulgar, and senseless work Hamlet is. The whole thing is based on pagan vengeance; the only aim is to gather together as many effects as possible; there is no rhyme or reason about it.
    Leo Tolstoy (1828–1910)

    He’s got a fifteen percent metabolism with an overactive thyroid and a glandular affectation of about three percent. With a one percent mentality. He’s what we designate as the Crummy Moronic type.
    Robert Pirosh, U.S. screenwriter, George Seaton, George Oppenheimer, and Sam Wood. Dr. Hugo Z. Hackenbush (Groucho Marx)
