Facts That you should Know

We people are unaware of pollution but there are many simple facts that will amaze all of us. After taking a look, think what we have done & then you can imagine yourself that what will be our  future.  Just take a look - 

1. For every one of the 6 billion people on earth, nearly four tons of carbon dioxide is spewed into the air annually.

2. World wide, rainforests are dissapearing at a rate of one and a half football fields per second. Each spring the forests beathe in oxygen and the earth breathes out again the following autumn, but like a heavy smokers lungs the earth is loosing its ability to breathe at all. Just a few centuries ago, earths equator was girdled by a green belt of 15 million sq. miles of rain forest, an area about 5-times that of contiguous US. Now the equiv. of 3 USA's worth of Forest are GONE! there is only 6.2 million sq. miles left ...

3. Americans consume 22% of the worlds oil, even though they make up just 5% of the world's population - as a result the past 100 years has seen heat trapping gases increase by 22%

4. Other 'warming gases' are; methane, nitrous, oxide and chloroflurocarbons (or CFC's). CFC's were invented by Thomas Midgley, Jr. whilst working for General Motors. CFC's exist at parts per trillion (ppt), however, each molecule has more than 12,000 times the heat-trapping potential of a molecule of CO2.

5. Our atmosphere was first compared to a "Glass Vessel" in 1827 by the French mathematicians, Jean-Baptiste Joseph Fourier. IN 1850 British physicist James Tyndall took things further and tried to measure the heat trapping properties of various componenets of the atmosphere. He discovered that (suprisingly) that the twomost common gases, nitrogen and oxygen, have no heat-trapping ability; 99% of the atmosphere has no insulating properties at all. It's up to a few trace gases, water vapour, CO2, methane and others to keep the planet cosy.

6. Importance of CO2 as earth's climate regulator was confirmed when scientists drilled out Ice Core in Antartica. They extracted a mile long cylinder of ice. Dating back 160,000 years they found an unbroken record of both temp and atmospheric levels of CO2; these two factors alone controlling previous thaws and ice ages.

7. Every time CO2 descends so do the temperatures. When temps were avg. 5oC, CO2 = 190ppm (parts per million) Throughout the 160,000 years the temps fluctuated between 190 - 280 ppm.

By the end of the 1900's CO2 = 300 ppm

8. In 1896 Arrhenius spelled out in an essay; "we are evaporating our coal mines into the air." You used to be able to stand on a hill and see up to 70 miles away, now you can only seeabout 15 miles.

9. In the year AD1 there were about 250million humans on earth. It took 1,650 years for that number to double. Between 1650 and 1930 the human population rose 4 times to 2 billion. By the turn of the century 6 billion on Earth - 3X the population just 70 years earlier. 

10. There are about 500 million cars on the planet and by 2030 it is expected to double to 1 billion cars ... It is believed that current fuel supplies peaked in 2006.

When you consider that the entire atmosphere of Earth weighs 5 million, billion tons, it seems okay - but remember only a little CO2 controls the warming.

                                                                                

                                                                                                                

THINK AGAIN

       We are responsible

         For What????

   For That  

                       Here is the result








 

Butterfly - Small Beauty

Butterfly one of the most beautiful animal in this earth.Is Now disappearing , vanishing  from earth  because of us.

We have destroyed natural flora & fauna for our earning , never thinking about the result who will the worst sufferer - 

"WE THE HUMAN BEING"

       

            

                

                  

                      

Its Time to wake Up

Its Time to wake up guys because we all are going to loose our home & killing ourself. Pollution increasing day by day & we are thinking that some one will stop making pollution i will do after him or her. Its a stupid thinking & like cutting the branch of tree in which your are sitting. 

  

Stop thinking & start Saving our Earth

We have already lost many things stop thinking otherwise we will have nothing to loose...........

Come on............

Start saving.................

So what can you do to save your future & make your future better........

1)Plant More as possible  

2)Save Drinking Water

   3)Don't be lazy & Walk or cycle instead of Car Driving

4)Try to recycle paper & plastic

5)Use eco-friendly products

6)Save Energy

7)In many ways you can do , just do it

If you ignore & continue this practice

then..........

  

This is your future.......

And this is you...

Then there will be no way...
No Way.........
Even not this way.........

So its better to go through this way


Start Saving your home from today





Your Home..........

You Can choose your future..

Rain Forest

Rain Forest

Rainforests are forests characterized by high rainfall, with definitions setting minimum normal annual rainfall between 1750–2000 mm (68-78 inches). The monsoon trough, alternately known as the intertropical convergence zone, plays a significant role in creating Earth's tropical rain forests.

From 40 to 75% of all species on Earth are indigenous to the rainforests. It has been estimated that many millions of species of plants, insects, and microorganisms are still undiscovered. Tropical rainforests have been called the "jewels of the Earth", and the "world's largest pharmacy", because of the large number of natural medicines discovered there. Rainforests are also responsible for 28% of the worlds oxygen turn over, often misunderstood as oxygen production. processing it through photosynthesis from carbon dioxide and through breathing to carbon dioxide.

The undergrowth in a rainforest is restricted in many areas by the lack of sunlight at ground level. This makes it possible to walk through the forest. If the leaf canopy is destroyed or thinned, the ground beneath is soon colonized by a dense, tangled growth of vines, shrubs, and small trees called a jungle. There are two types of rainforest, tropical rainforest and temperate rainforest.

OzONE Hole

The discovery of the Antarctic "ozone hole" by British Antarctic Survey scientists Farman, Gardiner and Shanklin (announced in a paper in Nature in May 1985) came as a shock to the scientific community, because the observed decline in polar ozone was far larger than anyone had anticipated. Satellite measurements showing massive depletion of ozone around the south pole were becoming available at the same time. However, these were initially rejected as unreasonable by data quality control algorithms (they were filtered out as errors since the values were unexpectedly low); the ozone hole was detected only in satellite data when the raw data was reprocessed following evidence of ozone depletion in in situ observations. When the software was rerun without the flags, the ozone hole was seen as far back as 1976.

Susan Solomon, an atmospheric chemist at the National Oceanic and Atmospheric Administration (NOAA), proposed that chemical reactions on polar stratospheric clouds (PSCs) in the cold Antarctic stratosphere caused a massive, though localized and seasonal, increase in the amount of chlorine present in active, ozone-destroying forms. The polar stratospheric clouds in Antarctica are only formed when there are very low temperatures, as low as -80 degrees C, and early spring conditions. In such conditions the ice crystals of the cloud provide a suitable surface for conversion of unreactive chlorine compounds into reactive chlorine compounds which can deplete ozone easily.

Moreover the polar vortex formed over Antarctica is very tight and the reaction which occurs on the surface of the cloud crystals is far different from when it occurs in atmosphere. These conditions have led to ozone hole formation in Antarctica. This hypothesis was decisively confirmed, first by laboratory measurements and subsequently by direct measurements, from the ground and from high-altitude airplanes, of very high concentrations of chlorine monoxide (ClO) in the Antarctic stratosphere.

Alternative hypotheses, which had attributed the ozone hole to variations in solar UV radiation or to changes in atmospheric circulation patterns, were also tested and shown to be untenable.

Meanwhile, analysis of ozone measurements from the worldwide network of ground-based Dobson spectrophotometers led an international panel to conclude that the ozone layer was in fact being depleted, at all latitudes outside of the tropics. These trends were confirmed by satellite measurements. As a consequence, the major halocarbon producing nations agreed to phase out production of CFCs, halons, and related compounds, a process that was completed in 1996.

Since 1981 the United Nations Environment Programme has sponsored a series of reports on scientific assessment of ozone depletion. The most recent is from 2007 where satellite measurements have shown the hole in the ozone layer is recovering and is now the smallest it has been for about a decade.

Our Green Earth

This is our home & but we are trying to destroy our home . To make ourselves orphan .



Global Warming

Global warming is the increase in the average temperature of the Earth's near-surface air and oceans since the mid-20th century and its projected continuation. Global surface temperature increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the last century. The Intergovernmental Panel on Climate Change (IPCC) concludes that increasing greenhouse gas concentrations resulting from human activity such as fossil fuel burning and deforestation are responsible for most of the observed temperature increase since the middle of the 20th century. The IPCC also concludes that natural phenomena such as solar variation and volcanoes produced most of the warming from pre-industrial times to 1950 and had a small cooling effect afterward. These basic conclusions have been endorsed by more than 40 scientific societies and academies of science, including all of the national academies of science of the major industrialized countries.

Climate model projections summarized in the latest IPCC report indicate that global surface temperature will probably rise a further 1.1 to 6.4 °C (2.0 to 11.5 °F) during the twenty-first century. The uncertainty in this estimate arises from the use of models with differing sensitivity to greenhouse gas concentrations and the use of differing estimates of future greenhouse gas emissions. Some other uncertainties include how warming and related changes will vary from region to region around the globe. Most studies focus on the period up to 2100. However, warming is expected to continue beyond 2100 even if emissions stop, because of the large heat capacity of the oceans and the long lifetime of carbon dioxide in the atmosphere.

Increasing global temperature will cause sea levels to rise and will change the amount and pattern of precipitation, probably including expansion of subtropical deserts. The continuing retreat of glaciers, permafrost and sea ice is expected, with the Arctic region being particularly affected. Other likely effects include shrinkage of the Amazon rainforest and Boreal forests, increases in the intensity of extreme weather events, species extinctions and changes in agricultural yields.

Political and public debate continues regarding what actions (if any) to take in response to global warming. The available options are mitigation to reduce further emissions; adaptation to reduce the damage caused by warming; and, more speculatively, geoengineering to reverse global warming. Most national governments have signed and ratified the Kyoto Protocol aimed at reducing greenhouse gas emissions.
