Weeds and tall grass grow through an abandoned sidewalk near the area
formerly known as the Love Canal, in Niagara Falls, New York, July 17, 2003.
25 years ago, Love Canal was America's most notorious toxic dump, where
leaking poisons from waste dumped by the Hooker Chemical Company (now
Occidental Chemical) forced thousands to flee their homes and awoke the
nation to the dangers of pollution. The U.S. government eventually declared
emergency evacuations of the area in 1978 and 1980, and relocated more than
800 families and reimbursed them for their homes, which were destroyed.

Locals stroll past an old 'traction' car in a quiet street in Colonia del Sacramento, 360 kms south of Uruguay's capital Montevideo. Colonia was built by the Portuguese 300 years ago on the coast of Uruguay as a bastion against the Spanish colony on the other side of the River Plate in what is now Argentina. In recognition of its beauty and historic value, Colonia was named part of humanity's cultural heritage by UNESCO in 1995, but some fear a planned $1 billion bridge to Argentina could disturb its peace and quiet.
