Overfishing is one of the destructive activities to our marine ecological system that directly involves man. Gross neglect and lenient implementation of fishing regulations will lead to the fishing industry collapse.
Rising sea levels are destroying the coral reefs that we are dependent upon for myriads of things. Protecting of these flowers of the sea means securing the coastal communities from storms, erosion, and tsunamis. Tourism will also be affected once coral reefs are depleted.
The Caribbean Coral Reefs, along with other reefs in the world, now has an increasing death toll. If no actions are done to save it, all coral reefs in the world can be wiped out in a decade. New efforts are in place to find a way to cure and rehabilitate reefs all over the world.
NASA pulled off a scientific double play in Hawaii this winter, using the same instruments and aircraft to study both volcanoes and coral reefs. Besides helping scientists understand these two unique environments better, the data will be used to evaluate the possibility of preparing a potential future NASA satellite that would monitor ecosystem changes and natural hazards.
