CO2 emissions are the major background of 'Global Warming', because the effect is the climate change in the Amazon basin. The rising sea temperatures in the Pacific Ocean result in less rainfall and a longer dry season in the Amazon Basin.
The Amazon rain forest is at present still acting as a buffer and is protecting us from the full effect of the global warming that would be created if all the CO2 we produce remained in the atmosphere.
Sustainability of the global environment is essential for agriculture and human life.
We must reduce the Carbon emission and we need to think green and to protect our earth for the irreversible impacts of global warming.
Gaining an understanding about green wind energy and green cars with lower CO2 emissions will be the first toppriority task.

The earliest burials of nobles at Saqqara can be traced back to the First Dynasty, it was not until the Second Dynasty that the first kings were buried there
The Cheops Pyramid has existed for 4,500 years, close to Cairo in the south. Completed in around 2,590 B.C, it took over twenty years to construct this huge monument on the edge of the desert. Although lacking the technology of today, amazingly, the pyramids were constructed with great architectural and astronomical precision. At a height of 128 metres, the Cheops Pyramid consists of more than two and a half million limestone blocks, each one of which weighs an average two and a half tons. As though standing guard, the Sphinx – a prone lion with a human head - has always been a symbol of mystique. It was carved from a single rock and measures 21 metres high and 74 metres long. The Cheops Pyramid is the most extraordinary tomb of all time, the tomb of a living god, and the most wonderful of the world's seven wonders of Antiquity!
