A Film for Earth''s Eleventh Hour
According to his publicist, Keleigh Thomas, DiCaprio has started
production on "11th Hour," which examines the issue of
global warming and offers “visionary and practical solutions” for reversing the
harmful effects of global warming and restoring many of Earth’s fragile
ecosystems.
"Global warming is not only the number one environmental challenge we
face today, but one of the most important issues facing all of
humanity," DiCaprio said in a statement. “We all have to do our part to
raise awareness about global warming and the problems we as a people
face in promoting a sustainable environmental
future for our planet.” Scientists have determined that a number of
human activities are contributing to global warming by adding excessive amounts of
greenhouse gases to the atmosphere. Greenhouse gases such as carbon dioxide accummulate in the
atmosphere and trap heat that normally would exit into outer space.
Greenhouse Gases and Global Warming
While many greenhouse gases occur naturally and are needed to create the greenhouse effect that keeps the Earth warm enough to support life, human use of fossil fuels is the main source of excess greenhouse gases
