Dr. Mikki McComb-Kobza is the new Shark Awareness Editor for DiveNewswire and highlights the importance of sharks in ocean ecosystems. Since the 1970s, shark populations have dropped by over 70%, threatening their role in maintaining a balanced marine environment. Sharks help control fish populations, and without them, the ocean ecosystem can collapse. Divers play a crucial role in advocating for shark conservation by promoting sustainable tourism practices. Educating others about the value and history of sharks is vital for their survival.
