Stern lectures for the logically-challenged. Others have opinions, I have convictions.
Coral reefs are underwater structures made from calcium carbonate secreted by corals. Corals are colonies of tiny living animals found in marine waters containing few nutrients. Most coral reefs are built from stony corals, and are formed by polyps that live together in groups. The polyps secrete a hard carbonate exoskeleton which provides support and protection for the body of each polyp. Reefs grow best in warm, shallow, clear, sunny and agitated waters.How exactly does pollution and human beings negatively affect them?I noticed how often the video mentions the reefs are endangered, but how? They don't explain. I wonder, is this another of the left's phony causes?
Nothing phony there, Mark. Coral Reefs are very fragile ecosystems and great strides have been made in creating artificial structures to support/create them. A myriad of coral fishes and animals live in and around them.They can be damaged by many sources, both natural and un-natural...
