Seventy-five percent of the world's coral reefs are currently threatened by local and global pressures, according to a 2011 analysis. The most immediate and direct threats arise from local sources, which currently threaten more than 60% of coral reefs. Local threats include impacts from fishing, coastal development, and pollution. Left unchecked, the percent of threatened reefs will increase to more than 90% by 2030 and to nearly all reefs by 2050. Grab a desktop wallpaper of this image.
