Home to millions of species, Earth is the only place in the universe where life is known to exist. The planet formed 4.54 billion years ago and life appeared on its surface within a billion years. Life formed about a billion years ago.
Earth's biosphere has significantly altered the atmosphere and other abiotic conditions on the planet, enabling the proliferation of aerobic organisms as well as the formation of the ozone layer which, together with Earth's magnetic field, blocks harmful radiation, permitting life on land. The physical properties of the Earth, as well as its geological history and orbit, allowed life to persist during this period. The world is expected to continue supporting life for another 1.5 billion years, after which the rising luminosity of the Sun will eliminate the biosphere.
The human race formed about 250,000 years ago. But they are capable of erasing the 4.54 billion years history. There won't be a 1.5 billion years needed to finish up the earth. If Human are living like this, we can kill earth before that!
Are there any possible way to open the eyes of those who are distroying the earth? Its time to wake up.

Solar Power
Solar energy is heat and light from the sun. This energy resource powers the climate and weather and sustains life on Earth. Solar radiation along with secondary solar resources such as wind and wave power, hydroelectricity and biomass account for over 99.97% of the available flow of renewable energy on Earth.
Solar energy technologies can provide day lighting and thermal comfort in passive buildings; potable water via distillation and disinfection; water and space heating; space cooling by absorption or vapor-compression refrigeration; high temperature process heat for industrial purposes; and electrical generation by thermal or photovoltaic means.
The Earth receives petawatts(PW) of incoming solar radiation (insolation) at the upper atmosphere. Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth's surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet.
This would be great if we are not hurting the Earth by digging for oil, gas and other mining activities, such as for diamond, coal, etc. There are many ways to get power solutions, which were given by the almighty himself for us. We have to utilize it. The initial cost may be high, but when compared to other solutions, the running cost is very low.
Why we won't change to it?

Solar Power and Wind Power
Let the Earth to breath. WE have to give little care to EARTH, WE have to reduce pollution.
There are other ways to produce power.
Solar power is another option. While we are making power using coal and other pollution making products we hurt Earth.
Solar and wind are the two better solutions for this. The nearby experiments proved that we can store heat, thereby make power later using this stored heat. This gives a great advantage to the solar power. During the night time and rainy seasons, we can use the stored heat.
"The sun may be about 148 million kilometers from Earth, but for many people, it is perhaps the most accessible power source when they think of 'green' energy. Solar power enjoyed a surge during the 1970's energy crisis, but where is it in the age of global warming? Increased attention on renewables has refocused the spot light on solar power, but today's solar is more than just photovoltaic cells on roof tops. "Mega Green Tech" explores the emerging world of Concentrated Solar Power (CSP), an evolving technology to harness the sun's rays on a massive scale to power entire communities. New CSP projects are thriving in hot spots like Nevada and Spain, where engineers race to tap this large-scale form of solar energy. But the technology is still dependent on one sometimes unpredictable factor: a sunny day. So a challenge remains -- to make solar more affordable and to somehow store its heat so this green energy can be relied upon whether rain or shine, day or night. We visit Nevada Solar One, a 400-acre solar field where hundreds of mirrors concentrate the sun's rays onto miles of high-tech tubing. A special oil that fills the tubes and is heated hot enough to generate steam-powered electricity, ultimately powering"-- National Geographic (Megastructures: Sun Engine)

Global Warming: Solutions
Global warming science
Global warming is already under way. The evidence is vast and the urgency of taking action becomes clearer with every new scientific study. Some of the most obvious signs are visible in the Arctic, where rising temperatures and melting ice are dramatically changing the region’s unique landscapes and wildlife—as well as people’s lives and livelihoods. Across the globe, other early warning signs include melting glaciers, shifting ranges of plants and animals, and the earlier onset of spring.
Global warming is caused by emissions of carbon dioxide and other heat-trapping gases that are emitted primarily by the burning of fossil fuels and the clearing of forests. These gases remain in our atmosphere for decades or even centuries.
The profound impact rising temperatures have had in the Arctic provides a window into a future we may all experience. With continued warming, we can expect more extreme heat and drought, rising sea levels, and higher-intensity tropical storms. At risk are our coastal property and resources, the livability of our cities in summer, and the productivity of our farms, forests, and fisheries.
We can’t avoid all the consequences of global warming, but committing ourselves to action today can help ensure our children and grandchildren inherit a healthy world full of opportunity.
Global Warming Solutions
We have the technology and ingenuity to reduce the threat of global warming today. Solutions are already available that will stimulate the American economy by creating jobs, saving consumers money, and protecting our national security. By investing in renewable energy and energy efficiency, and increasing the efficiency of the cars we drive, we can take essential steps toward reducing our dependence on oil and other fossil fuels that cause global warming.
Using energy more efficiently and moving to renewable energy (wind, solar, geothermal, and bioenergy) would significantly reduce our emissions of heat-trapping gases. The United States currently produces 70 percent of its electricity from fossil fuels such as coal, natural gas, and oil, but only two percent from renewable sources. Since the burning of fossil fuels releases large amounts of carbon dioxide—the leading cause of global warming—but renewable energy does not, increasing the share of our electricity generated from renewable resources is one of the most effective ways to reduce global warming emissions.
Cars and trucks are another significant source (25 percent) of U.S. carbon dioxide emissions. A serious effort to address global warming must therefore reduce emissions from cars and trucks. Many technologies already exist that can do this, while also creating new jobs in the U.S. automotive sector and other industries throughout the country. In addition, American consumers would save billions of dollars on gasoline, and we would reduce our dependence on foreign oil.
By putting energy efficiency, renewable energy, and vehicle technology solutions in place at the federal level, we can reduce our contribution to global warming while creating a stronger, healthier, and more secure nation.
Solutions to global warming - renewable energy, energy efficiency and new environmentally sound technologies - already exist.
The latest report from the International Panel on Climate Change (IPCC) confirms that hundreds of technologies are now available, at very low cost, to reduce climate damaging emissions, and that government policies need to remove the barriers to these technologies.
Implementing these solutions will enable people to usher in a new era of energy, one that will bring economic growth, new jobs, technological innovation and, most importantly environmental protection.
However, for green solutions to global warming to find a foothold in the market, governments and corporations need to shift away from polluting technology. In most industrial countries, conventional electricity is heavily subsidised, and the negative environmental impacts of its production are not reflected in the cost to end-users.
The time has come for us end our addiction to fossil fuels and other climate damaging technologies. Here you can discover how clean renewable energies, like wind, solar, bioenergy, hydroelectric and other sources can combine to create a clean energy revolution. Discover also the misleading myths about these solutions pushed by vested interests aiming to stop the clean energy revolution.

Chopping down trees in Indonasia
Watch out the video, actually it's showing the performance of the truck, but in the video you can see that, all the nearest trees were chopped down.

A Journey, 24 hours to travel 350 KMs
We, Me and my two roommates started from our house in Bangalore at 7AM and reached in Kannur, Kerala by 7AM next day.
We reached in Majestic KSRTC station by 8AM. It was on the Election day in Bangalore. So it was high rush in the buses. We didn't get any ticket to Kerala, to our place or to Mysore or to Mangalore. Even the chain service VOLVOs are also full. The high speed, non-stop Volvo bus will take normally a two hour journey to Mysore from Bangalore.
We took a decision, to go to Mysore by train. If a high speed bus will take the 140KM journey in 2 hours, then how much time will a train take to travel the same distance. Any how, not more than 2 hours. We took ticket to Mysore, it was only Rs.22, and it was a passenger train. We got into the train by 9:45, the train left the station by 10:10AM.
We got seats in the train. The train too was full. Normally four people will be sitting in a seat, but there were 6 or 7 people sitting in a seat. As per the information we got from the other passengers, the train will take a four hour journey and there are about 28 stations in the route. On hearing this shocking fact, we understood that, it will be very late to reach in destination. In normal case, if we are going in night service bus, it will take only 8 or 9 hours to reach in my native place.
The train which we got in took five and half hours to reach in Mysore. The train was travelling two and half hours and the train stopped three hours for crossing. After about one hour the sathabdi express passed us, for that it took one hour stop for our train. After that a lot of train passed us and there were crossings, for all these the train stopped for three hours.
At last the train reached in Mysore by 3:30PM. After having lunch by 4'o clock, we got the next bus to next station by 5'o clock. The bus reached in Gonikoppal, its nearest to the Karnataka Border, by 8PM. From there the last to Kerala was at 6:30. So, we gotta stay there. We had dinner, we waited there for our regular bus, which left bangalore at 9PM. The bus reached at 1AM mid night, we took the bus and reached home by 7AM.
This is the story of the Great Journey from Bangalore to My place, which usually taking maximum of 10 hours, but we took 24 hours.
It was not our fault at all. We haven't waste any time by ourselves. While at the crossing, the first train passed us was satabdi express, the third crossing stop was also for the same train. It was coming back from Mysore. Why the railway scheduled such a time table for the trains? It was not a rare case.
Even there is not a good road to Kannur, Kerala. Through the forest, there's a way down to Kerala, but the road is full of gutter, and except the heavy vehicle, no other vehicle can travel through the road. Many of the four wheelers can be seen broken down in the road.

GLOBAL WARMING
Stop chopping down the trees... That's all the way to stop increasing global warming.
It's more than the suffer able...
For an example, in earlier days, Bangalore was the Garden City of India, but now a days, for the development of roads and buildings, a number of trees have been removed. It may need to do so. Because, people need shelters, so they need to build new houses and roads...
But is there any way, not to demolish the environment we leave?
