 Let's talk about the health of our oceans. Oceans are the planet's life support as they support the global population's economic, social, and environmental needs. They are the world's largest ecosystem and regulate the global climate system. Sadly, decades of irresponsible exploitation have led to an alarming level of degradation. The problem lies in debris, plastic, CO2, and tourism. Increasing levels of debris in the world's oceans has a major environmental and economic impact. Every year, an estimated 5 to 12 million metric tons of plastic enters the ocean. The ocean absorbs around 23% of annual CO2 emissions and also absorbs more than 90% of the excess heat in the climate system. Consequently, ocean heat is at record levels threatening its rich ecosystems and killing coral reefs around the world. About 80% of all tourism takes place in coastal areas. If not managed carefully, tourism can pose a major threat to marine life. So what can we do? International cooperation is vital for the protection of vulnerable habitats. Establishing government-protected areas to conserve biodiversity and ensuring a sustainable future for the fishing industry is essential. We should eliminate plastic usage as much as possible and get involved with beach and ocean cleanups. In addition, people must be encouraged to make ocean-friendly choices when buying seafood or products derived from oceans. Most importantly, spread the message about how important marine life is and why we need to protect it.
