The environment is an inseparable part of our life, we live and prosper on it. We must adjust to it to survive on Earth and are therefore dependent on it. But in a world that is market based and has a focus on productivity, the environment and nature have been abused. This has resulted in a range of pollutions that are affecting not only the Earth but its inhabitants that could pose very dire future consequences. One of America’s most prevalent environmental problems is nutrient pollution.
In recent years, with rapid growth of global population hitting 7 billion in 2011, and expected to rise to 9 billion in the year 2050. With this, comes the increase in demand for food and water resources. The growing population leads to increased agricultural activities to feed the demands of the population. There has since been a controversy on the severity of the increase in agricultural activities, creating concern on freshwater pollution because these activities are inevitable. On one hand, this is an essential detrimental cycle, so it is inevitable.
Mining is a major economic activity in many developing countries such as Ethiopia (Tauli, 1997: UNEP,1997).Operations, whether small or large-scale, are inherently disruptive to the environment, producing enormous quantities of waste that can have deleterious impacts for decades (UNEP, 1997). The environmental deterioration caused by mining occurs mainly as a result of inappropriate and wasteful working practices and rehabilitation measures. Mining has a number of common stages or activities(exploration, development and mining stage), each of which has potentially-adverse impacts on the natural environment, society and cultural heritage, the health and safety of mine workers, and communities based in close proximity to operations (Moody and
Food that is intended for human consumption but not consumed or not used for its purpose is waste of resources such as land and water. Food production is part of agriculture activities that is land and water intensive. Agriculture is considered to be one of the greatest contributors to global warming by emitting greenhouse gasses Therefore, food waste will also results in emitting unnecessary CO2. Nonetheless agriculture is considered also as the main driver of biodiversity loss by turning forest into farm land considered to be major polluter due to the usage of fertilizer as well as manure produced throughout the activity. Food lost or wasted happened through the entire journey in the food supply chain of developed and developing countries.
Eutrophication of waters is a classic example of the impact of rapid economic development on the environment. In most cases, the primary cause of eutrophication is phosphorus, although nitrates are also a significant (and increasing) contributor in certain circumstances, particularly in saline estuaries and marine waters. Excess inputs of phosphorus, and nitrates, are contributed by nearly all sectors of economic activity – domestic, public, industrial and agricultural. Besides the main sources, such as discharges of sewage and industrial wastes and losses from agricultural activities, fish farming, forestry development and even road building and other types of land disturbance may lead to phosphorus losses to waters and consequently eutrophication on a local
WEST AFRICAN MONSOON REGIMES Introduction The West African monsoon (WAM) is a very important climatic event in the West African region because it produces most of the precipitation for the region which still depends mostly on rain-fed agriculture for their livelihood (Nicholson and Grist, 2003; and Sultan et al, 2008). This is weather system is most important in the Sahel area of the region, where rainfall is highly variable and any anomaly in the rainfall regime could mean untold hardship to the millions of people that depend on it (Baron et al, 2005). Therefore, understanding the mechanisms and the parameters that most significantly contribute to the variability of the WAM would be greatly beneficial to the region’s agricultural development
It is important to all the manufacturing processes of beverages, and is required to produce the agricultural ingredients on which the entire business of Coca-Cola depends upon. Water is a limited resource in many countries of the world. It is facing challenging problems from growing population, increasing pollution, changing climate and overexploitation. Water is becoming scarce and the quality available is detoriating as its demand is continuously increasing across the globe. Because of this Coca-Cola may incur higher production costs or face capacity constraints that could adversely affect the profitability or net operating revenues in the long run.
Both are natural parts of aquatic ecosystems, and beneficial to them in moderate amounts as they aid in the growth of the algae and aquatic plants that provide food and habitat for fish, shellfish and smaller organisms that live in water. However, agricultural pollution has caused the amount of nitrogen and phosphorus in the Chesapeake Bay to increase exponentially; in turn causing algae to grow faster than the ecosystem can handle. This is called eutrophication, which is defined as the excessive growth of plant life on the water’s surface, most commonly in the form of algal blooms. Eutrophication depletes dissolved oxygen levels in the water and is prevalent in the Chesapeake Bay;
The waste has been a major environmental issue or common everywhere since the industrial revolution. Besides the waste we create at home, school and other public places, there are also waste those comes from hospitals, industries, farms and other sources. Humans rely so much on materials things and they all end up as waste. Bhutan being a small Himalayan Kingdom landlocked between India and china, where “Gross National Happiness” philosophy is the guiding spirit for the development process, sustainable development. There are number of environmental issues in Bhutan.
In addition solid wastes resulted from agricultural sectors causes high disposal problems. For that stringent regulations are issued all over the world to control the discharged of solid and liquid wastes. Egypt faces a big environmental problem resulted from the discharging of a huge amount of industrial wastewater and the accumulation of agricultural solid wastes, both represent a negative environmental impact. With increasing environmental awareness, strict regulations are issued in Egypt to protect the environment and natural resources and to control the discharge of industrial wastewater such as law 48/1982 (article 66) and its modification , which deals with the maximum allowable limits for the discharge of industrial wastewater into water courses. Dyes are used in dyeing of many industries such as, textile, leather, plastic, cosmetics and food industries to color their products.
