A concerted push in Florida to forestall global warming could benefit the state’s economy by creating 27,000 new jobs in environmentally friendly industries, according to a study conducted by the Tellus Institute for the World Wildlife Fund. Such an effort would also reduce air pollution in the state by cutting harmful emissions from power plants and automobiles. Florida is considered particularly vulnerable to the rising sea levels expected to be caused by global warming, and climatic changes would also threaten the state’s coral reefs, water supply, and Everglades ecosystem.
