Coral reef pollution. Discarded bottle being colonised by coral. Coral organisms are already growing on much of the bottle, and over time it will be incorporated into the reef. Coral reefs are found in warm water, at depths no deeper than 60 metres. They are very diverse and productive ecosystems, providing shelter, food and breeding grounds for many marine species. They are increasingly under threat from humans who pollute and over-fish the reefs, disturbing their delicate balance. Photographed in the Red Sea, Marsa Alam, Egypt.
