Air pollution
In Mexico City, only 31 days in 1993 had air considered fit to breathe
In Bombay, India, breathing the air is equivalent to smoking ten packs of cigarette a day.

 

Sun
The amount of sunlight reaching the earth's surface is 6,000 times the amount of energy used by all human beings worldwide.

 

The total amount of fossil fuel used by humans since the start of civilization is equivalent to less than 30 days of sunshine.

 

Ice
The United States uses an estimated 10 million tons of salt each year to melt ice on the roads.

 

Erosion
Annual soil loss in South Africa is estimated at 300 - 400 million tonnes, nearly three tonnes for each hectare of land.

For every tonne of maize, wheat, sugar or other agricultural crop produced, South Africa loses an average of 20 tonnes of soil.

The FAO (Food and Agriculture Organisation, a branch of United Nations) estimates that the global loss of productive land through erosion is 5-7 million ha/year.
