Saving Earth

Throughout history, humans have searched for better energy sources and better ways to harvest energy. A rough estimation of mankind’s energy consumption through different periods of history is displayed in the figure.

From 1945 to 1962, the U.S military detonated many atomic and hydrogen bombs in the atmosphere. One of the few cameramen who documented the explosions and their destructive effects George Yoshitake,82,shares his experiences

In a surprising new research, scientists have said that although the hole in the ozone layer is now steadily closing, but its repair could actually increase global warming in the southern hemisphere.
The Antarctic ozone hole was once regarded as one of the biggest environmental threats, but the discovery of a previously undiscovered feedback shows that [...]

Here is the list of 10 worst nuclear accidents in history.
windscale Fire, October 10, 1957
The accident occurred when the graphite core of a British nuclear reactor caught fire. The fire resulted in a release of a significant amount of radioactive contamination. It was estimated that the incident caused an increase in thyroid cancer cases.No [...]

A typical search through the online giant’s website is thought to generate about 7g of carbon dioxide. Boiling a kettle produces about 15g.

The emissions are caused both by the electricity required to power a user’s computer and send their request to servers around the world.

The discovery comes amid increasing warnings about the little-known environmental impact of computer and internet use.

According to Gartner, an American research firm, IT now causes about two per cent of global CO2 emissions and its carbon footprint exceeded that of the world’s aviation industry for the first time in 2007.

Dr Alex Wissner-Gross, a physicist from Harvard University who is leading research into the subject, has estimated that browsing a basic website generates about 0.02g of CO2 for every second it is viewed.

Websites with complex video can be responsible for up to 0.2 g per second, he believes.

A rise of at least two meters in the world’s sea levels is now almost unstoppable, experts told a climate conference at Oxford University on Tuesday.
“The crux of the sea level issue is that it starts very slowly but once it gets going it is practically unstoppable,” said Stefan Rahmstorf, a scientist at Germany’s [...]

No doubt human population growth is a major contributor to global warming, given that humans use fossil fuels to power their increasingly mechanized lifestyles. More people means more demand for oil, gas, coal and other fuels mined or drilled from below the Earth’s surface that, when burned, spew enough carbon dioxide (CO2) into the atmosphere [...]

Here is a list of 10 major oil spills in history that caused severe oil pollution and irreparable damage to the ecosystem.
