Desert: An Unexplored beauty

Desert is said to be the most unexplored place. But it has its own beauty-unknown. I guess, that is why its beautiful because it is not being touched by humans. The largest desert in the world is "Sahara Desert". The major deserts in the world are:

Sahara Desert (North Africa)
Arabian Desert (Saudi Arabia)
Great Sandy Desert (North Western Australia)
Thar Desert (India; Rajasthan and some part of Pakistan)
Simpson Desert(Central Australia)
Takla Makan Desert (Central Asia)
Gobi Desert (Mongolia and China)
Sonoran Desert(North America)
Kalahari Desert
Atacama Desert

The Sahara Desert is a great desert area in North Africa that extends from the Atlantic Ocean eastward past the Red Sea to Iraq. The entire desert, the largest in the world, is about 1600 km wide and about 5000 km long from east to west.
The total domain of the Sahara Desert is more than 9,000,000 sq. km, more than 3,500,000 square miles, of which 80,000 square miles consist of partially fertile oases.The boundaries, however, are not clearly defined, and have been shifting for a thousand years.

Desert National Parks are also in attraction. The Desert National parks are the excellent example of the ecosystem of the Thar desert and the diverse fauna. Sand Dunes form around 20 % of the national park.

Unfortunately,one day, due to growing mechanization, whole world will become desert.

Pollution:Effect on World

"There's so much pollution in the air now that if it weren't for our lungs there'd be no place to put it all". -Robert Orben

True saying....Either it may be Air Pollution,Sound pollution or Water pollution every bit of it is hazardous.

According to a study, pollution is changing world's weather by creating large clouds and intense storms. Researchers say there is definitely a link between human activity and the changing weather conditions. Increasing urban pollution can be blamed for intensified electricity and lightning in storms over various cities.

China has not only its name in increasing population but also in increasing pollution. Chinese pollution is the deadliest in the world. A World Health Organization (WHO) report estimates that diseases caused by air pollution kill 656,000 Chinese citizens each year.

WHO's air guidelines warn that pregnant women, the sick, and young children are especially susceptible to suffering severe effects from high pollution levels.
