42 Coral Reefs
Unless you’re scuba diving or snorkeling in tropical waters, you won’t ever get to see nature’s wide variety of stunning coral reefs. Coral are animals and have been reef building for the past 25 million years. Most reefs that you see today have taken between five to ten thousand years to form, and all together form more than 5,000 miles of reefs. Although coral reefs sustain a healthy balance to underwater life, they are very fragile and are being destroyed by climate changes and dying from pollutants in the oceans.
