"The 'dead zone' in the Gulf of Mexico, an area choked by low oxygen levels that threatens marine life, is smaller than expected this year but more deadly, the government said on Monday.
The zone, caused by a runoff of agricultural chemicals from farms along the Mississippi River, measured about 3,000 square miles or about 1.5 times the size of the state of Delaware, compared with estimates that it would measure up to nearly 8,500 square miles, scientists said."
