I'd say there is a problem, because the marine environment has evolved to handle a certain amount of use, but it's not adapted to the threat of modern technology. We now have the ability through new technology to track animals down, hunt them, kill them and consume them in ever greater numbers and with ever increasing speed. They can't keep up. And there are many other examples. It's hard to convince people not to do something that is fashionable.
People feed on each other.
Behaving in an environmentally responsible manner has to become fashionable. My topic is on the overuse of seahorses and sea cucumbers in Asian medicines and foods. These things are supposed to have aphrodisiac-like properties and are being over harvested in many areas. Other local and international celebrities are also assisting with similar PSAs to help educate people and increase awareness about these issues, as well as to help people understand their own impact on the environment. It's our responsibility as consumers to control what we buy and use.
