Making mistakes in dealing with nature will lead to serious consequences,Humanity already posses fundamental scientific technology to over come this.
A. Ozone layer protection- Recovery and destruction of Fluorocarbons( CFC, HCFS,HFC) from refrigerator, Air-conditioner.
B. Decrease Co2 levels:
1. Domestic effects- By usage of Photo voltaic power generation, wind power generation, Hydro Power generation,Fuel cell,Co2 reduction by providing IT Solution,
Energy managements.-Air conditioning control system,control system for water purification.
Modernize electricity grid.preferance to power devices,LSIs systems,Display panel.
2. Promotion of life style-Usage of solar system ,High efficacy mileage vehicle.Go green (plant more trees),Usage of vehicles should be minimized,Go paperless work ( it decreases Forest destruction)
C. Control measures against deforestation:constructing multi story buildings.Usage of electronically communications Instead of Paper.Reducing consuming the products made From wood.
D. Monitor measurement for acid deposition, Dust & sand storm:By monitoring sulphur oxide, nitrogen oxide in Oxygen r& rain water. And reducing it thru Minimizing combustion of fossil fuel.
E. Glacier environment protection: By decreasing global warming with all these steps.
F Marine environment protection:By preventing land-based contaminants such as, toxic chemicals and nutrient salts which would cause eutrophication as well as by pollution from off-shore such as oil spills and accidents associated with marine transport.

effects of global warming
Effects of global warming:
Lets see the effect of Global warming ,Global warming not only causes glacier melting due its paradoxical effect it also sucks moist from earth.
A. glacier melting;
· Kilimanjaro lost more than 50% from 1970 to 2008.
· Grinnell glacier (Atlanta), lost > 70 from1910 to1998.
· Columbia glacier (Alaska) lost >60 from 1980 to 2006.
· Glacier AXO10 (Nepal) from 1978 to 2004 lost its 45%.
Glaciers are the drinking source of water for > 40% of world population (by means of springs, rivers etc)if glaciers melts in this rate then in next 50 yrs, these 40% population are gonna face shortage of drinking water.
B.sea ice melting;
In Antarctica the largest ice shell “Larsen” has completely broke down between Jan 31st to march 05 of 2002. Artic also facing similar consequences.( studies shows that polar bear are loosing life in search of finding ice to land in spite of swimming More than 60 miles)
Sea ice extend has dropped by 1.5 million km2 since 1970,( in next 50- 70 yrs it will be completely gone) This causes increase in sea water level, leading to flood
Little evidence;
· Switzerland aug/23/2005
· Brienz aug/26/2005
· Austria aug/23/2005
· Asia , India Mumbai- July 26/2005,37 inches of rain in single day.
· Also in china.
C. Suction of moisture from earth; Leads to increase in temperature and draught. Lake Chad once largest in world now its no more persist.
Relation between Temperature and Co2:
In past thousands of yrs Co2 level never went beyond 300(ppmv),but in 2008 ,It was 400 in2008( ppmv) in next 50 yrs its gonna be double.
ð When there is more Co2 presence it increases temperature by thickening of atmosphere, trapping more heat from sun inside the atmosphere.
ð Ten hottest yrs on record ever measured occurred in last 14 yrs as on 2005( 1991, 1995,1997,1998,1999,2001-2005)
ð If 1 degree F increased in equator it results in rise of 12 degree F in poles. In 2003 heat wave resulted in 35,000 deaths in Europe. In India June 2003 Andhra recorded 50 degree C. In USA more consecutive days of high temperature were recorded.
Facts we are facing:
These changes also shifts the seasons, for eg in Netherlands in 1980 bird migration occurred during end of April and egg hatches during June 1st wk( when caterpillar comes out)But after 2000, caterpillar hatches 2 wks earlier around mid may,Chicks tries to hatch during may end, but with little success of survival. In USA western pine Beatle around 4 million acre were destroyed. We are loosing more species as fast as ever.
New diseases around 30 emerged in past 25 yrs Few eg- Ebola, Arena, Honta virus, Pulmonary syndrome,SARS, multi drug resistant TB.
Re-emergence of disease once were controlled-Avian flu, west Nile fever,
What will happen if we don’t act now?
ð When north Antarctica melts, worldwide sea level will rise up to 25 ft.
ð If half of Greenland n north Antarctica melts, then we have redraw the world map, yes
Florida will shrink to 50%
San Francisco will loose 20%
Nether land >35%
Shangai>40%
Beijing >20%
Calcutta n east Bangladesh >35%

causes of global warming
“what gets us in to trouble is not what we don’t know ,its what we know for sure that just ain’t so”
Usually what happens is Solar radiation in form of light waves passes thru atmosphere, most of these are absorbed by earth, and this warms earth,some of these radiation is reflected back in to space in form of Infra red( IR ) waves, some of out going IR radiation is trapped by atmosphere, this warms earth again .
What leads to Global warming:
Increased Co2 due to various causes, leads to thickening of atmosphere causes more of out going IR trap -->more warm trapped -->Global warming.
We are witnessing a collision between our civilization and earth’s eco system.
Factors that causing this collision.
Population- (in 1945 it was 2.3 billion, in 2008- 6,706,993,152)it took 10,000 yrs to reach 2.3 billion but in one Human life time it went beyond 6 billion.This leads to increase in demand of food & Water supply, demand on vulnerable natural sources E.g.-devastating of forest.( 30% of Co2 comes from forest burning ).
Increase in usage of products, technologies which causes more Emission of Co2.( carbon emission per Person is high in USA, when compared with other developed & Developing countries)
Ozone layer depletion-due to increase level of fluorocarbons.
Acid deposition, dust & sans storms.due to excess combustion of fossil fuel there is increase sulphur oxide, nitrogen oxide in Oxygen r& rain water.
Marine pollution.by means of toxic pollutant like Poly-aromatic hydrocarbons (PAHs) a toxic pollutant ,typically come from oil pollution and burning wood and coal.
Marine garbage disposal is another major form of ocean pollution includes junked out fishing nets, plastics, general household garbage, sewage disposal in marine. Other sources like farmland (fertilizers, manure), industrial runoff (heavy metals, phosphorous), urban runoff (oils, salts, various chemicals)
Contribution to global warming- USA-30.3%,Europe-27% Developing countries-20% ,
