MarineBio is deeply committed to marine conservation and founded on the concept that, by sharing the wonders of the ocean and marine life, people will be inspired to protect it. We hope you will consider becoming a MarineBio Conservation Society member to help us bring the ocean and the conservation message to as many people as possible. There are many other organizations working on marine conservation and other environmental issues such as biodiversity and global warming.
