Among the most harmful and dangerous non-metal compunds are nitrogen oxides‚ sulphur dioxide‚ carbon dioxide‚ carbon monoxide‚ and hydrogen sulphide. These can cause devastating effects to human beings‚ plants‚ animals and the environment. Matals are generaly less harmful‚ although lead is extremely toxic. Hydrogen sulphide is a highly toxic gas. It has a very bad smell‚ often identified in rotten eggs and stink bombs. Hydrogen sulphide interferes with cellular respiration. If inhaled‚ Hydrogen

human-caused pollution. Earth’s atmosphere contains mostly water vapor‚ carbon dioxide‚ and methane (natural greenhouse gases) which act to keep the lower layers of the atmosphere warmer than they otherwise would be without those gases. Greenhouse gases trap infrared radiation. The radiant heat energy that the Earth naturally emits to outer space in response to solar heating. Mankind’s burning of fossil fuels releases carbon dioxide into the atmosphere and this is believed to be enhancing the Earth’s

and dispose of carbon dioxide. In order for this to happen‚ at least four events called respiration must occur. The first is the pulmonary ventilation. The air must move in and out of the lungs so that the gases in the alveoli are continuously refreshed. This process is better known as “breathing”. Next is external respiration‚ when a gas exchange between the alveoli and the pulmonary blood must take place. Then there is respiratory gas transport‚ where oxygen and carbon dioxide are transported

to our environment. The carbon cycle starts off in many different ways‚ fossil fuels‚ respiration‚ and factory emissions. Then as the cycle continues‚ carbon that is transmitted into the oxygen will then be taken in by plants and animals as they intake vegetables and other autotrophic organisms. Then as organisms and waste products die‚ they will start the process of decomposing and begin returning the carbon that they have taken during their lifetime. Without the carbon cycle‚ many of the worldly

is because the trees act as carbon sink‚ fight soil erosion and as the windbreak and sound barriers. Firstly‚the role of trees act as carbon sink in our environments everyday which are really vital for the life.As we know that the trees are the largest and longest living organisms in earth‚ it’s aslo a forest act as carbon storage area or a "sink" that can locks up as much carbon dioxide produced by human being and animals.When we release the carbon dioxide and water vapour from our lungs

Also when a volcano erupts; sulphur dioxide‚ water vapor‚ dust‚ and ash go into the atmosphere and it can cool the atmosphere. Another natural effect on climate is from ocean currents. Ocean currents carry large amounts of heat across the earth. The ocean current pulls warm water toward the poles and brings it towards the equator. When the currents push back out towards the pole it brings with it warm water. Since water evaporates it can pull with it carbon dioxide into the atmosphere. The third

Synthesis Essay Along with many other problems‚ global warming has become one of the top issues in the world. As the consequence of emitting carbon dioxide‚ the world’s temperature has risen from the past. Despite the fact that there is statistical evidence‚ there have been controversies as in how much effort should be put in to solve the issue of global warming. The seriousness of global warming is evident. “In the 20th century‚ the world’s average surface temperature rose by… the fastest rate

polluting the Earth’s atmosphere and are one of the many reasons why the Earth has an increasing surface temperature. Carbon Dioxide or C02 is a by-product of the combustion or burning of fossil fuels such as coal and oil‚ it is present at the highest concentration out of the Greenhouse Gases in our atmosphere (Kreger C‚ November 2004). Based on 1990 concentrations‚ carbon dioxide is said to be responsible for almost 60% of the total greenhouse effect. Its concentration is increasing in the atmosphere

economy more reliant on solar energy‚ hydrogen gas‚ wind biomass‚ and other renewable energy sources. The term greenhouse effect is used to describe the increased warming of the Earth’s surface and lower atmosphere due to increased levels of carbon dioxide and other atmospheric gases that absorb radiated energy in the atmosphere and then reradiate it back to the surface. But if it were not for the greenhouse effect‚ temperatures at the Earth’s surface today would be much colder then they are now
