ENVIRONMENTAL PROBLEMS

ENVIRONMENTAL PROBLEMS Our environment is constantly changing. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters people need to be aware of what types of environmental problems our planet is facing. Current environmental problems make us vulnerable to disasters and tragedies, now and in the future. Unless we address the various issues seriously we are surely doomed for disaster. Current environmental problems require urgent attention. 1. Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicle exhaust are the number one pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by

Essay on water pollution, global warming, acid rain, deforestation, intensive farming

Scientists first discovered acid rain in 1852, when the English chemist Robert Agnus invented the term. From then until now, acid rain has been an issue of intense debate among scientists and policy makers. Acid rain, one of the most important environmental problems of all, cannot be seen. The invisible gases that cause acid rain usually come from automobiles or coal-burning power plants. Acid rain moves easily, affecting locations far beyond those that let out the pollution. As a result, this global pollution issue causes great debates between countries that fight over polluting each other's environments. For years, science studied the true causes of acid rain. Some scientists concluded that human production was primarily responsible, while others cited natural causes as well. Recently, more intensive research has been done so that countries have the information they need to prevent acid rain and its dangerous effects. The levels of acid rain vary from region to region

Yet, power, greed and politics have affected the precarious balance. Why Is Biodiversity Important? Who Cares? · Why is Biodiversity important? Does it really matter if there aren't so many species? · Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. · For example, a larger number of plant species means a greater variety of crops; greater species diversity ensures natural sustainability for all life forms; and healthy ecosystems can better withstand and recover from a variety of disasters. · And so, while we dominate this planet, we still need to preserve the diversity in wildlife. Loss of Biodiversity and Extinctions · It is feared that human activity is causing massive extinctions. From various animal species, forests and the ecosystems that forests support, marine life.

A letter and an essay

The most common methods are by burning coal, building dams, or using nuclear power. However, many people think that nuclear power is dangerous, and when you consider the experience of Chernobyl in the Ukraine over 20 years ago, you can see why. Countries such as France, however, get about 80% of their electricity from nuclear power plants, and the pro-nuclear scientists argue that it is actually much clearer than burning fossil fuels, which contributes to global warming. Others argue that it is better to get electricity from sustainable resources, such as the wind, the sea, and the sun. Although this sounds like a sensible idea, they are not reliable enough to malntain a constant supply of power. For instance, you cannot produce solar energy at night. Basically, we need a source of energy that will not run out; if it cannot be hydroelectricity or coal-fired energy, it will have to be nuclear

Biogas – The source of future energy

to other applications. By trapping the gases, people can prevent methane from reaching the atmosphere, thereby reducing degradation caused by methane gas. The ability to turn waste products into something which can be utilized is also rather convenient, especially in developing countries, where available resources may be limited. Furthermore, by turning biomass into biogas, people can address issues like sewage treatment, ensuring that raw sewage is not released into the natural environment.  Producing process Biogas is normally produced by using the excreta of animals as the source material. In most of the countries where biogas is produced, the excreta of the cattle and other farm animals are used. In India gobar or cow dung is used for the purpose of making biogas. 20% of the excreta of animals are made up of dust particles that are inorganic in nature. The percentage of the inorganic dust particles is brought down by

Education

WE are here and are ready to participate in educational projects designed to lead the USA in the first countries in the world. European educational system with its broad coverage of humanities, collective work, discipline, obligatory level of knowledge for an educated person can contribute to the American system of education. This new system of education can be a model for other countries to follow. It would be easier to live and understand each other in this shrinking world, in this global community.

user’s reality is much closer to “billboard going by at 60 miles anhour.” As you might imagine, it’s a little more complicated than this, and it depends on the kind of page, what the user is trying to do, how much of a hurry she’s in, and so on. But this simplistic view is much closer to reality than most of us imagine.  It makes sense that we picture a more rational, attentive user when we’re designing pages.It’sonly natural to assume that everyone uses theWebthe same way we do, and—like everyone else—we tend to think that our own behavior is much more orderly and sensible than it really is.
