You can help conserve this gorgeous Great Barrier Reef, a consistently popular choice among the 28 finalists in the New 7 Wonders of Nature competition. According to NOAA, “Even if you don’t live near a coral reef, you can still have an impact on them. Awareness is a big step towards changing behaviors that threaten reefs, and ensuring your impact on reefs is a positive one. Therefore, we all need to be aware of the importance of, and threats to, coral reefs.” Photo #1 by NOAA’s National Ocean Service
