Might your children or grandchildren someday live in a world without rhinoceroses or African elephants? The chances of that are probably higher than you might guess. There are just 350,000 elephants remaining on African savannas, one-tenth the number in 1900. And the population is estimated to be shrinking by 27,000 a year.
