Usa Water Resources - 461 words
Water is the most important life element to humans after oxygen. Without water human can live only up to 3 days after which they would die. Today water represents a great and profitable industry for the fact that the producers of the main US soft drinks need water, as well as the ordinary citizen who use water for their household needs, let alone for the lawn use. In the following essay I am going to speak about the water industry as being overvalued with respect to the green (social) economy based on various examples, literary findings as well as my personal opinion on the given matter. Water in the USA in my personal opinion is undervalued for numerous reasons, most of which are unrealized ...

Crop Production - 879 words
Beginning about 12,000 years ago, the human population began a trend that completely changed the way we, as a race, evolved. For the first time in history, humans pushed beyond the restraints of traditional hunting and gathering, into domestication and farming. It was a change that would not only take thousands of years to prove worthy, but also may have set us back on the evolutionary path at the time. Along the path to this point, we have been constantly changing and finding new ways to produce and maximize the yield of the crops we sow. Have these changes been successful or detrimental to us? The following will search into answering this question. Since the beginning, increased crop produ ...

... d and water management, including sediment transport and storage in lowlands, reservoirs, estuaries, and irrigation and hydropower systems. In the USA, soil has recently been eroded at about 17 times the rate at which it forms: about 90% of US cropland is currently losing soil above the sustainable rate. Soil erosion rates in Asia, Africa and South America are estimated to be about twice as high as in the USA. FAO estimates that 140 million ha of high quality soil, mostly in Africa and Asia, will be degraded by 2010, unless better methods of land management are adopted.

... ave evolved in response to local agro-ecological and socioeconomic condition. However, intensification with these technologies alone is unlikely to be sufficient in most Sub-Saharan African countries to achieve agricultural growth rates of 4 percent per year and more. Improved variety/fertilization/farm mechanization technologies will also be necessary. Increased use of fertilizers will be especially important to raise yields and maintain soil fertility. Intensive and resource-conserving agriculture must be made less risky and more profitable. This requires appropriate marketing, price, tax and exchange rate policies as well as investments in rural infrastructure, health and education fa ...

Many of these activities involve the use and disposal of chemicals, which are potential pollutants. When these chemicals are used or disposed of incorrectly unacceptable amounts can get into the ground water and contaminate it. Several valuable aquifers have been polluted by the people living and working above them. Most human activities at the land surface cause some change in the quality of water in the aquifer beneath them. The importance of the effect of a particular activity is related to the amounts and types of c ...

Tuskegee National Forest - 557 words
The 11,000 acres now known as the Tuskegee National Forest was originally a vast cotton field, home to sharecroppers. These sharecroppers planted cotton each year until the soil was no longer fit for yielding crops. This incidence caused the sharecroppers to relocate to Shorter, Alabama. This also allowed those same 11,000 acres to be established as the Tuskegee National Forest. Much of the forest is a lone leaf pine ecosystem that contains plants such as blue stem grass, blueberries, yucca, and L. bicolor, which is a rampantly growing weed that is a popular food source for deer. This weed, however, has proven to be a problem for rangers because it grows so uncontrollably. Forest management ...

Wed And Sustainable Development - 1,893 words
At the present rate of development, according to many scientists, the world will reach critical mass sometime within the next fifty years. With these doomsday predictions, many development models have come under scrutiny for their shortsightedness and lack of environmental concerns. Over the past thirty years, those affected most, or more appropriately, those who are being forced to bear the brunt of the negative impacts of these development programs the most, have increasingly become themes that have not only brought to light serious defects in Structural Adjustment Programs (SAPS) and other development programs, but have also critically assessed the very social fabrics that have encouraged ...

Our second proposal involves desalinization. Desalinization is the process of making salt water into good drinking water. Renewing U.S. leadership on desalinization technology will yield untold benefits, a quote from Paul Simeon says that we are running out of water, but look, 80% of the world is covered with water, and we should be able to use it like fresh water. That is exactly what a desalinization plant does. It allows the human race to use salt water by treating it, and extracting the salt from it, a ...

... ysical, thermal, and sometimes the chemical properties influence the performance of concrete. Aggregate is cheaper than cement and it is, therefore economical to put into the mix as much of the former and as little of the latter as possible. But economy is not the only reason for using aggregate: it confers considerable technical advantages on concrete, which has a higher volume stability and better durability than hydrated cement paste alone. General classification of aggregates: The size of aggregate used in concrete ranges from tens of millimeters down to particles less than one-tenth of a millimeter in cross-section. The maximum size actually used varies but, in any mix, particles of ...

Global Warming - 1,351 words
How can the nations of the world work together multilaterally to successfully address the problem of global warming? The numbers are striking. No region of the world will be unaffected if Global Warming continues to increasingly grow. Yet day after day people take actions that can change the earth and its climate in significant ways. Many people just stand motionless as the wave of climate change becomes more apparent. The IPCC predicts that during the next century, the average rate of warming will be greater than anything seen in the last 10,000 years. Global sea levels could rise by at least fifteen and perhaps as much as ninety-five centimeters. Surface temperatures could increase by betw ...

Environmental Problems In Africa - 1,782 words
The environmental problems seem to be key challenges of the XXIst century. In the previous years the world politics and every person in general was occupied with politics and wars. But with the development of new technologies, with the increasing number of plants and factories all kind of manufacturing in general, a huge shift was made towards the environmental issues. The terrestrial, freshwater and marine environments have declined in virtually all aspects. New developments in industry and manufacturing were root causes of environmental degradation over the past three decades. The rapid growth of population, urbanization and globalization are the driving force of the environmental problems ...

Global Warming: A Deadly Threat For Human Life - 1,458 words
Global warming is one of the major environmental issues facing the world today. Global warming refers to an average increase in the Earth's temperature, which in turn causes changes in climate. An increase in the temperature of the Earths surface may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. One cause for Global Warming is called the Greenhouse Effect. The Greenhouse Effect results from a four step process. First, sunlight radiates from the sun, through space, to Earth's atmosphere. Second, the sunlight enters the atmosphere and hits Earth. Some of it turns into heat energy in the form of infrared light. The heat i ...

Women And The Law - 1,289 words
Through out the years there have been many factors that affect the operation of the legal system to help generate just outcomes for women. Historically, women have always held an inferior place to men, but during the 20th century this concept has changed considerably. The status of women has changed in terms of political suffrage, jury duty, economic rights, property rights, social security and minority groups. However, women still suffer disadvantages and to try to resolve particular problems women still confront legal and non-legal mechanisms. The mechanisms are used to resolve political and economic equality in accessing education, training development, gaining promotion, equal pay and se ...

The Dangers Of Water Pollution - 689 words
Non-point Water Pollution has always been a major problem throughout the world, especially the United States. The lack of suitable water used for drinking, agriculture, farming, etc. has declined through the years. With a shortage of water in most of the United States, proper methods of treating an recycling water is the key goal in sustaining our limited water resources supply. Most people believe that the largest source of water pollution comes form a pipe, which originates from factories and sewage treatment plants. But the fact is that the largest source of water pollution in rivers, lakes, and streams does not come from pipes, but from surface run-off. This type of pollution is called n ...

Global Warming - 1,603 words
By the middle of the twenty first century, there is evidence that the Earth will be warmer than it has been at any time in human history, and quite possibly since the end of the dinosaurs, some 65 billion years ago. If we stay at the rate we our now (fossil fuel consumption / growth in population) then within the next two century the Earth's air might not be fit to breath. Many people in the world do not think that this is a major concern and that it is normal for the Earth's temperature to increase. However, if this temperature increase is put into perspective of several hundred years, there will be many devastating effects. This is why most scientists view global warming as a very serious ...
