Environmental problem intro the answer to break faced with global problems in the beginning. Cimmyt, with the slowing of the lower atmosphere? It can be in the form of the physical environment, biophysical environment, built environment, social environment and the natural environment among other forms. The natural environment refers to the naturally occurring flora and fauna together with the land on which they occupy.
Environmental issues have been a cause of a lot of debate in the recent past. The ozone layer protects humans, animals, and plants from harmful ultraviolet rays. Money and time are being spent on ozone repair, but the problem still exists. They have looked at many solutions and continue to find new methods of saving our ozone layer. Oxygen in the presence of sunlight forms Ozone. Both are essential for life but air also protects all of us and it is therefore understandable that the response to the depletion of the ozone layer became international.
This essay will look at what the ozone layer is, why it was depleting, how the international response to this situation developed and what this collaboration means for our future. The ozone layer shields the entire Earth from some of the harmful ultraviolet rays that come from the sun. So, it's difficult to imagine the problems they would run into when a group of environmentalists decide to boycott a substance which is the foundation of their company.
These chemicals, although very useful, cause consequences that need to be dealt with now in order to prevent further damage. But CFCs favorable qualities—versatility, durability, high efficiency, low cost, and lack of toxicity—have made them an integral part of the U.
The chemicals serve as a coolant for modern refrigerators and air conditioners, as a foaming agent for Styrofoam insulation and foam rubber, as a solvent for computer chips and dry cleaning, and as a propellant for aerosol-spray products. Costs are likely to increase for a wide range of consumer products and services because few of the alternatives to CFCs will be as inexpensive to produce.
In addition, product substitutes may not be able to operate as efficiently as those using CFCs, resulting in higher their energy consumption. The key question for policymakers is whether we should rush to eliminate these chemicals from production—imposing greater hardships on ourselves and on our economy—or wait for more alternatives to emerge, thereby imposing more serious environmental and health consequences on future generations.
Robert W. Atmospheric chemist F. Sherwood Rowland , of the University of California, Irvine, formulated the theory in the early s. This is not because of scientific proof, but the result of the constant reiteration of disaster scenarios that range from skin cancer to DNA damage.
Pronouncements in the past few weeks give the impression that all atmospheric scientists are believers, which is far from true. Many of us are still skeptical because of incompatibilities between the theory and what we know about the ozone layer.
The Rowland theory ignores the equilibrium nature of ozone in the layer. The ozone molecules are constantly being created and destroyed— both quite naturally— by the very short wavelengths of ultraviolet light from the sun. The amount of ozone in the layer depends upon an equilibrium between the two processes.
This equilibrium varies markedly both over the globe and throughout the year. At very high altitudes a disrupted equilibrium is restored in a matter of minutes; at lower levels in the stratosphere, in a matter of weeks or months. In any event, repair takes place rather quickly.
Depletion of ozone can occur only by reducing the equilibrium density of ozone molecules.
Pronouncements in the past few weeks give the impression that all atmospheric scientists are believers, which is far from true. If we fail to protect our ozone, the earth will become one big frozen and lifeless ball.
Ppt, who helped discover the ozone is showing its consequences for people throughout the ozone layer and cultures through november ozone hole. In other words, the paucity of measurable proof of depletion may be because depletion is not actually occurring. More about ozone depletion and the research papers - complete unit.
