How to fight against global worming ?

You should read  this before continue this article..There are non-flying vacuum-like machines inside power company smokestacks. They are called "scrubbers." What they do is capture the CO2 coming up a smokestack before it gets into the air, and the concentrated CO2 is then gathered, transported and eventually shoved down a hole. Usually a deep hole, where it's supposed to sit for a long, long time.
The advantage is extra CO2 doesn't get into the air. The disadvantage: It's expensive to isolate CO2, expensive to transport, expensive to find and fill a hole, and the hole might leak.
The other possibility is to use less carbon. We rely on oil and coal and natural gas (all carbon-based) to heat ourselves, cool ourselves, light our homes, drive our cars, run our businesses. Carbon is, even now, cheap, abundant and releases energy easily. That's why it has been popular since the first cave person burnt a log. But carbon is not the only atom in town. We can shop around.

4 rivers declared ecologically critical

Bangladesh Inland Water Transport Authority (BIWTA) on December 15 declared the four rivers and its foreshores, adjacent to the capital, ecologically critical to save the rivers from encroachers and pollution.
They banned dumping sewage from home, industries and other institutions, setting up industries which pollute soil, water, air and sound and any work which can change the natural character of rivers Buriganga, Turag, Shitalakhya and Balu.

pollution free energy source

Now energy is produced from the following sources

• Coal -(Disadvantages: Pollution/Strip Mining)
• Natural Gas - (Disadvantages:Cost and Lack of Infrastructure)
• Hydro - (Disadvantages:Limited Availability/Environmental Concerns)
• Wind - (Disadvantages:Limited Site and Resource Availability)
• Solar Photovoltaic - (Disadvantages:Higher Cost)
• Nuclear – (Disadvantages:Waste disposal)

Among this power sources Solar PV (Photovoltaic) systems effectively deliver 10 Watts per square foot. Not one square inch of new land would be required to site PV. Theoretically, there are adequate residential, commercial, Government rooftops, and parking structures in California to power a substantial percentage of our State's electrical needs from solar.
At today's prices, a typical solar system costs approximately $6.00/watt, installed and has an operating life in excess of 25 years. For all intents and purposes, maintenance and operating costs are minimal.

What can you do about Global Warming ?

 Carbon dioxide is a colorless, odorless gas. It is produced both naturally and through human activities, such as burning gasoline, coal, oil, and wood.

Are you wandering that i start this topic with Carbon dioxide ?? Carbon dioxide is the main green house gas cause for global worming.So CO2 emission produced by your car is a cause of  the global warming.So what can you do ? Many thing you can do just decrease your petrol or gas consumption by car.Do not use the car if you in long ride.Another nice solve can be the use of pollution free Hybrid vehicle.

Effect of Carbon dioxide in global worming

Carbon dioxide is a colorless, odorless gas. It is produced both naturally and through human activities, such as burning gasoline, coal, oil, and wood.The carbon dioxide itself can cause headache, dizziness, nausea and other symptoms.CO2 plays an important role in the energy balance of our planet: It acts like a blanket over the planet by trapping long-wave radiation, which would otherwise radiate heat away from the planet . CO2 in the atmosphere will remain for a very long time, of the order of thousands of years.

To alleviate global warming, the emission of greenhouse gases like Carbon dioxide (72%),18% Methane and 9% Nitrous oxide (NOx) must be reduced.see effect of global worming in natural life.
It is seen that Carbon dioxide emissions therefore are the most important cause of global warming.The emissions of CO2 have been dramatically increased within the last 50 years and are still increasing by almost 3% each year.

QUIVER TREE This striking giant aloe was given its name by the San people of southern Africa, who use the tree's hollow branches as quivers for their arrows. Scientists have discovered that quiver trees are starting to die off in parts of their traditional range. The species might be in the early stages of moving southward, trying to escape rising temperatures closer to the equator.

PINON MOUSE This tiny resident of the southwestern U.S. has long eked out its living in juniper woodlands, but in California it is heading for higher, cooler altitudes in the High Sierra conifer forests. The mouse is one of several small mammals in the region that have moved their homes 1,000 to 3,000 ft. higher in elevation over the past century.

RED-BREASTED GOOSE Twenty-six bird species, including this goose, which breeds in the Arctic, are listed by the World Conservation Union as threatened by global warming. Half are seabirds whose food supplies are diminished because of climate changes. The rest are terrestrial species, including several whose coastal habitats are at risk because of rising sea levels.
