The U.S. Environmental Protection Agency estimates that 10 percent of the world’s coral reef population has already been damaged, and a much higher percentage is threatened. Exploring the Environment’s new coral reefs module takes a comprehensive look at this real danger to Earth’s biodiversity and why it should concern us. Check out the Modules and Activities section for this look at coral reefs along with many other real-life environmental issues.
