Water pollution is starting all over the world. Water pollution occurs when waste products or other substances, such as microorganisms, chemicals, or sewage, change the physical, thermal, chemical or biological characteristics of the water, adversely affecting living species and reducing the water's beneficial uses. When the matter gets into the water, most of the time it deteriorates and makes the water unhealthy. When the water becomes polluted, animals that rely on the water source will die from drinking the harmful chemicals and other pollutants. These chemicals will not only harm the animals but will affect the plants greatly as well. The plants will stop growing and eventually will die. There are several threats to our water resources. Oil Spills kill thousands of seabirds and can wreck water desalination plants and industrial plants drawing their water from affected coastlines. However, oil can get into the sea from many other sources, and cause just as much damage. Poor management of existing water resources can lead to those resources running out or at least shrinking. Much of the pollution in rivers and seas comes from chemicals, mainly from agriculture. The effects of pollution can vary from localized damage to disturbance of the ecology of an entire waterway. The impact of pollution depends on the type and amount of contamination, the period of…

The causes of air pollution seem to stem from carelessness or blatant unconcern. Every Sinic citizen who drives a car that is not properly serviced and that does not have emission control devices is contributing noxious gases into the atmosphere. Large industries that do not have filtration mechanisms on their smoke stacks are also contributors. Every government which does not pass or passes but does not enforce strict air pollution legislation is also destroying the atmosphere. One may wonder why these three aspects of society show such a lack of concern with the air they breathe. Well, the underlying cause which motivates all three groups is money. Legislation and enforcement of laws and installation and maintenance of filtration systems cost money. The majority of these three groups seems content to save a bit of money now and sacrifice an invaluable commodity later.…

Every day when looking out a window, people see a beautiful earth. The earth is intriguing, but hinges on a delicate balance. Many natural resources keep the grass green and the sky blue. Man has made quite an impression on our world, and has transformed the earth's resources into tools to make life easy. However, mans' manipulation on earth has become detrimental to the health of our planet and the safety of mankind. Through the use and production of resources such as oil and energy, man is gradually poisoning the earth. Pollution has become such a dilemma in society; there is no real control or a feasible solution to society's recklessness. Without complete change, our system will collapse. The earth will eventually retaliate with disaster, or corporate control of our economy will cause hysteria and depression. Evaluation of the consequences and repercussion of worldwide pollution, may give people a better idea of what the future holds.…

Water is probably one of the most important resources we have. People can survive without food for several weeks but without water we couldn't live for more than a week. Millions of liters of water are needed every day worldwide for washing, irrigating crops, and cooling industrial processes, not to mention leisure industries such as swimming pools and water sports centers. (Internet Source) Despite our dependence on water, we use it as dumping ground for all sorts of waste, and do very little to protect the water supplies we have. There are several threats to our water resources. Oil spills kills thousands of seabirds and can wreck water desalination plants and industrial plants drawing their water from affected coastline. (EBSCO CD-ROM source) Poor management of existing water resource can lead to these resources running out or at least shrinking. Much of the pollution in the rivers and seas comes from chemicals, mainly from agriculture. Another pollution issue, which is not brought up often, is thermal pollution. As you can see we have many problems in our waters and we need to protect the waters.…

1. Coastal landscapes are being transformed as a consequence of the increasing demand for urban infrastructure to sustain commercial, residential and tourist activities. A variety of man-made structures, such as breakwaters, jetties and seawalls have thus become ubiquitous features of intertidal and shallow subtidal habitats. This transformation will accelerate in response to the exponential growth of human populations and to global changes, such as sea-level rise and increased frequency of extreme meteorological events (e.g. storms). Here, we provide a critical overview of the major ecological effects of increasing infrastructure to marine habitats, we identify future research directions for advancing our understanding of marine urban ecosystems and we highlight how alternative management options might mitigate their impacts.…

We now face the worst global environmental problems: global warming, air pollution, lack of fresh water, degradation of oceans and forests.

Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions, or in the distribution of weather around the average conditions (i.e., more or fewer extreme weather events). CAUSES: Climate change is caused by factors that include oceanic processes (such as oceanic circulation), variations in solar radiation received by Earth, plate tectonics and volcanic eruptions, and human-induced alterations of the natural world; these latter effects are currently causing global warming, and "climate change" is often used to describe human-specific impacts. Global warming is the rise in the average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. EFFECTS: The effects of an increase in global temperature include a rise in sea levels and a change in the amount and pattern of precipitation, as well a probable expansion of subtropical deserts. Warming is expected to be strongest in the Arctic and would be associated with the continuing retreat of glaciers, permafrost and sea ice. Other likely effects of the warming include a more frequent occurrence of extreme-weather events including heat waves, droughts and heavy rainfall, ocean acidification and species extinctions due to shifting temperature regimes. Effects significant to humans include the threat to food security from decreasing crop yields and the loss of habitat from inundation.…
