That’s why today the contradictions between man and nature are dramatic. People are slowly destroying the nature environment around them. Today we are anxious about the state of the air we breathe because every year world industry throws out into atmosphere about 1 000 million tons of dust‚ smoke and other harmful substances and people of many cities suffer from smog. | Another reason why there is such high level of air pollution in large cities is because of car exhaust fumes from very intensive

Acid rain is caused by the numerous acidic pollutants‚ which have potential to damage earth’s environment in a drastic way. Acid rain is caused due to the presence of chemicals like Sulfur Dioxide and Nitrogen Oxides in the atmosphere. These chemicals are introduced in the atmosphere as a result of the industrial processes. Sulfur Dioxide is emitted out of those industries that use coal as

look at the science involved‚ their assertions appear to be groundless. First‚ carbon dioxide is not a pollutant as many claim. Carbon dioxide is good for plant life and is a natural constituent of the atmosphere. During Earth’s long history there has been more and less carbon dioxide in the atmosphere than we see today. Second‚ they claim that climate is stable and slow to change‚ and we are accelerating climate change beyond natural variability. That is also not true. Climate change is generally a

Global Warming The greenhouse effect‚ in environmental science‚ is a popular term for the effect that certain variable constituents of the Earth ’s lower atmosphere have on surface temperatures. It has been known since 1896 that Earth has been warmed by a blanket of gasses (This is called the "greenhouse effect."). The gases--water vapor (H2O)‚ carbon dioxide (CO2)‚ and methane (CH4)--keep ground temperatures at a global average of about 15 degrees C (60 degrees F). Without them the average

human health‚ air pollution can cause a variety of environmental effects: Acid rain is precipitation containing harmful amounts of nitric and sulfuric acids. These acids are formed primarily by nitrogen oxides and sulfur oxides released into the atmosphere when fossil fuels are burned. These acids fall to the Earth either as wet precipitation (rain‚ snow‚ or fog) or dry precipitation (gas and particulates). Some are carried by the wind‚ sometimes hundreds of miles. In the environment‚ acid rain damages

Global warming is commonly referred to as an increase in the temperature of the lowest layers of Earth’s atmosphere. Global warming has occurred in the distant past as the result of natural influences‚ but the term is most often used to refer to the warming predicted to occur as a result of increased emissions of greenhouse gases. Primary greenhouse gases include

of plants called (transpiration). But this water doesn ’t just disappear; it ’s absorbed into the atmosphere and carried around the world by currents of air. Eventually the water in the air condenses to form clouds‚ which return it to Earth as rain or snow. The water that collects on land flows back to the oceans in rivers or streams-to begin the cycle all over again. This interaction between atmosphere and ocean is what gives us our weather and climate which is known as Atmospheric Circulation/Convection

AQUA SILENCER SYNOPSIS This project is an attempt to reduce the toxic content of diesel exhaust‚ before it is emitted to the atmosphere. This system can be safely used for diesel power packs which could be used in inflammable atmospheres‚ such as refineries‚ chemicals processing industries‚ open cost mines and other confined areas‚ which demands the need for diesel power packs. WORKING PRINCIPLE The aqua silencer is more effective in the reduction of emission gases from the engine exhaust gas
