Forest Service Tens of millions of trees have died in the Rocky Mountains over the past 15 years, victims of a climate-driven triple assault of tree-killing insects, wildfires, and stress from heat and drought. Costly and growing health impacts Photo: Rising temperatures will likely lead to increased air pollutiona longer and more intense allergy seasonthe spread of insect-borne diseasesmore frequent and dangerous heat wavesand heavier rainstorms and flooding. All of these changes pose serious, and costly, risks to public health.
Hire Writer Findings show that a single smokestack may produce as much as tons of sulfur dioxide a day. When these gases combine with oxygen and moisture, sulfuric acid and nitric acid is formed.
The rain will carry the acids to the ground acid rain which may cause the depletion of calcium and magnesium in the soil, elements needed by plants for the formation of chlorophyll and wood, or it may cause the release of aluminum in the soil, which are poisonous and can kill the roots of trees Carwardine, This study intent to: Literature Review Ozone is an unstable oxygen that occurs naturally in the atmosphere also called isothermal regionthe upper portion of the atmosphere above 7 miles where clouds are rare.
The ozone layer absorbs the dangerous ultraviolet-B UV-B rays while it allows the needed safe light to pass through. It is being destroyed by industrial gases like CFCs Johnston, CFCs are estimated to account for 14 percent of global warming.
It is dismaying to know that ozone depletion can be found in the south Antarctica and north Greenland poles Dolan, According to British scientist Joe Farman, 40 percent of ozone depletion can be found in the South Pole.
At the South Pole is a huge vortex with clouds composed of tiny ice particles, giving chlorine millions of tiny spaces through which it can perform its deadly dance with ozone even faster Simpson, Both holes at the poles are seasonal, opening and closing each year.
In the northern hemisphere, a more populous region, ozone depletion rate is between three percent and seven percent for 17 years, as compared previously to only three percent for years.
On the other hand, what are the effects of Ultraviolet-B rays to human beings and the ecosystem in general? To humans, they can cause skin cancer and cataract and damage the immune system. To the ecosystem, they can kill planktons basic element of the ocean food chaindestroy plant life and crops and change global wind and weather patterns.
However, other uses of CFCs were found, effecting an increase in its production. However, in September24 nations cooperated for the first time to solve this environmental problem and passed the Montreal Protocol.
The agreement issued a call for developed nations to freeze the use and production of CFCs while cutting 50 percent of use and production by Still, the CFCs currently rising through the troposphere will take seven to 10 years to drift up to the stratosphere.
Methodology In order to accomplish this study, the researcher used two different methods to make the investigation more informative, accurate, and successful. Aside from gathering information through internet, the researcher gathered information through statistics, charts, and observation.
Results and analysis During the earliest times, the life-styles of our ancestors were very simple. The air they breathed was clean. The streams were clear and free of harmful organisms. They used natural fertilizers for their agricultural crops.
The surroundings were free of household throwaways. Today, there has been a tremendous growth in science and technology. Such advances have brought about changes in terms of new products, improved equipment, and more effective methodologies. Unfortunately, this same technology which made life easier for us produced wastes which are now affecting the quality of our surrounding, air, water, and land.
Factories and motor vehicles send tons of pollutants into our air. Excessive air pollution poses a danger to our health and environment. It can likewise cause stunted growth and even death to our plants. Out streams are polluted by discharges from industrial plants that use chemicals.
Garbage and sink wastes are carelessly thrown in our surroundings. Synthetic fertilizers and insecticides pollute our land and farm products Johnston, At the same time, the burning of fossil fuels, particularly coal and oil, produces sulfur dioxide and nitrogen oxides which are hazardous to the atmosphere.
Findings show that a single smokestack may produce as much as tons of sulfur dioxide a day.
When these gases combine with oxygen and moisture, sulfuric acid and nitric acid are formed Jenner, The rain will carry the acids to the ground acid rain which may cause the depletion of calcium and magnesium in the soil, elements needed by plants for the formation of chlorophyll and wood, or it may cause the release of aluminum in the soil, which are poisonous and can kill the roots of trees.
Cattle, sheep, goats, and other cud-chewing animals give off methane, in burps and flatulence as they digest Cairncross, Experts said that what is happening right now is not a matter of adding a few degrees to the average temperature of a community.
A rise of this magnitude may cause life, for without the environment, creatures on earth cannot survive Davidson, A rise of this magnitude may cause life, for without the environment, creatures on earth cannot survive With these, are we all aware of the extent of the damages brought about by modernization?'Global warming' is one facet of the broader term 'climate change'.
It is the increase in the average temperature of the Earth's surface air and oceans from the midth century, and the projected continuation. The global warming controversy is an ongoing dispute about the effects of humans on global climate and about what policies should be implemented to avoid possible undesirable effects of climate.
Essay writing on global warming. Global warming is not a prediction.
It is happening right now. It is a current increase in temperature of the Earth `s atmosphere, water, and surface. According to the National Climate Assessment, human influences are the number one cause of global warming, especially the carbon pollution we cause by burning fossil fuels and the pollution-capturing we prevent by destroying forests.
Global Climate Change In , the earth’s surface temperature was around Celsius degrees warmer than the 20th century average. In the last few years, global temperatures have been. Confounding the international policy challenge is the disproportionate impact of high oil prices and global warming across nations, insulating some countries from immediate concern while forcing.
