Picture this,

a blue planet protected by a thin layer of atmosphere, that keeps temperature, air and water in perfect balance to maintain life.

In the cold depth of space, this planet is a virtual paradise, the only one known of its kind and it’s our planet, earth.

But something is wrong, the life sustaining systems on this planet are breaking down. What happened? Us, human civilization and our relentless consumption has brought this planet to the brink. But specifically, our destructive addiction to one single resource may push us over the edge
and that resource is oil.
Oil is essentially ancient sunlight, since the dawn of time plants captured sunlight, after billions of years of decomposing in the earth, this fossilized sunlight become a fuel, oil, coal or gas. This ancient sunlight has become modern civilization's battery pack. The problem is, oil is a finite resource. We are running out of the very thing our society is depending on in order the function.
But worse, our burning of oil and other fossil fuels has dumped over 700 billion tons of carbon pollution into the atmosphere, as if it were a sewer.
The warming of the last 20 years is caused by human activity.

We are altering life on this planet as we know it. How? The accumulated pollution causes the atmosphere to trap more of the sun's heat, the earth surface temperature is actually going up, this is what is known as global warming.

Coal burning power plants, automobile exhausts and factory exhaust fumes contribute billion tons of carbon dioxide and other greenhouse gases into the earth's atmosphere each year. Additionally, animal agriculture, manure, natural gas and rice cultivation contribute about 250 million tons of methane each year. About half of human emissions have remained in the atmosphere. In view of this fact, the atmospheric concentrations of CO2 and CH4 have increased seriously above pre-industrial levels since 1750. About three-quarters of the anthropogenic emissions of CO2 to the atmosphere during the past 20 years is due to fossil fuel exhaustion. The rest is predominantly on account of land-use change, especially deforestation.

Warming, that almost sounds inviting, that in a world 20 years from now we will all be living in a tropical paradise, with the extent of our problems will be pondering which SPF sun cream to use, but don’t be fooled.
Thousands of climate scientists agree that global warming is not only the most threatening environmental problem,
but one of the greatest challenges facing all of humanity.

The 1990s alone have been the warmest decade in the entire millennium. Temperature has already gone up by one degree Fahrenheit in the last century. Maybe that doesn't sound like a lot, but it is. It only took 4 small degrees to shift us out of the last ice age.

During the next decades the earth’s climate will change dramatically. This fact is undisputable among scientists. One important sign provides the rising temperature which has risen for 0,6 degree during the 20th century. Scientists draw a scenario of a climate catastrophe: due to melting continental ice the ocean circulation gets out of balance. Referring to recent studies by Professor Harry Bryden the Gulf Stream is reduced for 30% between 1992 and 2004. As a consequence of this the temperatures in northern Europe could drop. The worst scenario includes resisting snow in the summer so that the continental ice field will grow and cover large areas thus an escape of humans and animals will be necessary. In order to completely understand the reasons for a possible climate change resulting from global warming, both anthropogenic and natural reasons should be examined in detail.
Both advocates and opponents of the human-induced global warming theory call increasing natural disasters a sign for a climate change. The number of storms over the Atlantic Ocean has risen significantly, from which some caused tremendous damages in middle Europe. Furthermore, one have to allude the direful flood waters of diverse rivers in Germany in 2002 which appear today every second year instead of every 50 years like in former times. Not to mention the horrible draughts in the USA which led to 40% crop loss in 2003. Among scientists it is beyond all question that accumulating extreme weather events represent a first hint for the expected climate change.

When you turn on the TV and you hear about killer heat waves, extreme weather conditions, freak storms, drastic flooding of cities, rising sea levels, giant chunks of ice breaking off in the Antarctic, coral reefs bleaching out and dying,
make the connection:
it is global warming and climate change.
In the face of this disaster,

what have corporations and politicians done about it? Unfortunately, not enough. The fact is they have gained too much money and power off our addiction to oil. This makes them dangerously resistant to change. But are we?

We must demand a separation between oil and stain, we can get off oil and slow down global warming, we can use energy more efficiently and support renewable clean energy sources, new green technologies that don’t burn carbon like hydrogen fuel cells, wind and solar power, we can vote for leaders who care about protecting your health, the air and the environment.
We can support non-profits who are making a difference.
We can be environmentalists, so get educated, stay educated, so we can think for ourselves, and join the fight to safe this unique blue planet for future generations.
