Sharing the Earth's Resources:

The U.S., with just 6% of the population, uses 30% of all energy produced--a stark contrast to India whose 20% of global population uses only 2% of the energy. To sustain a reasonable quality of life requires about 80 liters of water per person per day. But the average consumption ranges from 5.4 liters a day in Madagascar (barely enough to survive) to 500 liters a day in the U.S. During the decade 1970-80, the numbers of rural people without clean water increased by 67 million to 1.15 billion, while those without proper sanitation rose by 300 million to almost 1.4 billion. Numbers lacking sanitation in Third World cities doubled during the period 1975-80.
