The health or our oceans are critical for sustainable life on Earth. See our pages for important articles on oceanography and marine science topics. More than 70 percent of the Earth's surface is covered with water. Let's help keep them healthy. All fishermen and divers should take a concerted effort to conserve and protect our ocean and marine resources. It is necessary to ensure that we have fertile fishing and diving grounds for years to come. We want our children and grandchildren to enjoy even better outdoor experiences in the future.
