Mitigation Strategies and Solutions Human Population The world population in 2007 was 6.6 billion, jumping up from 6.1 billion in 2000 and it is projected to rise to 9.3 billion by 2050. Exactly these specific numbers indicate a major problem for humankind and the environment. The human population holds the responsibility of negatively influencing all the important environmental issues such as atmospheric pollution, water resources, terrestrial resources and energy conservation. Therefore, in order to fix one problem after another, the root of these problems needs to be addressed first (Population reference Bureau, 2007). Problem Four factors come into play and are responsible for the steady increasing population on this planet and they are birth rate, death rate, immigration and emigration. So if the birth rate and immigration increases, the death rate and emigration decreases and so does the size of population. The Global Growth Rate (2008) stated, “Every minute we are adding 140 more people to the world, over 200,000 more every day, over 70 million more every year.” These numbers are staggering because as the population increases, the problems of food production, water supply, energy production, and environmental destruction become more prominent. Contributing Factors Negative human impacts Food production plays an important aspect of overpopulation when trying to meet all the consumption needs on this planet. As omnivores, human beings consume almost anything regardless of the consequences and therefore animal-based food production is a cause of most major environmental problems like global warming, air pollution and so on, which happens by

destroying too much land and by not restoring any of it.“The livestock sector generates more greenhouse gas emissions as measured in CO2 equivalent – 18 percent – than transport. It is also a major source of land and water degradation,” (Matthews, 2006, para.1). On top of that there is the transportation of produce that is still done by air (uses the most fuel) or by land and sea (uses less fuel) causing additional greenhouse gases. Furthermore, there is the land that is abused for much less important things such as building new tobacco plantations. For example, the forests that are being cleared out can lead to soil degradation and failing yields and the pesticide run-off from the plants is released into the groundwater that we drink. Not even to mention the trash that is created afterwards by the filters of the cigarettes that can cause over 500,000 tones of pollution per year (McLaren, 2005). Water supply is a resource that without it, the human population cannot survive and live. Water is needed to meet many basic needs such as drinking but is also required for agriculture, manufacturing, mining, energy production, and waste disposal. However, the technologies that are being used are not up to date, too expensive or are wasteful like the water that is used for agriculture. The traditional irrigation methods flood the lands by where only 40% of the water is absorbed by the plants, leaving the rest to evaporate. Also, this being a renewable source, it is

What students are saying

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
