Lead in paint and the health hazard posed by exposure through inhaling or swallowing lead-based paint prompted Congress to pass a federal lead based paint disclosure form requirement in 1996, called the Residential Lead-Based Paint Disclosure Program, or Title X.hat Lead-Based Paint Disclosure Laws Require. 1  Under federal EPA and lead disclosure rules, a lessor or seller of private or public housing built after 1977 must use a lead paint disclosure form to disclose any known information concerning lead-based paint or lead-based paint dangers or hazards.
The Permian-Triassic extinction The largest of the Big Five was the end-Permian or Permian-Triassic extinction event roughly 250 million years ago, which eliminated as much as 95 percent of the planet's species. Before this extinction, marine animals were mostly filter feeders stuck in place on the seafloor, such as crinoids or sea lilies.
There have been five mass extinction events in Earth's history. In the worst one, 250 million years ago, 96 percent of marine species and 70 percent of land species died off. It took millions of years to recover. Nowadays, many scientists are predicting that we're on track for a sixth mass extinction. The world's species already seem to be vanishing at an unnaturally rapid rate. And humans are altering the Earth's landscape in far-reaching ways: We've hunted animals like the great auk to extinction. We've cleared away broad swaths of rain forest.
