Marine environment protection involves safeguarding the oceans and seas from pollution, overfishing, and habitat destruction. This includes efforts to maintain the health of marine ecosystems, such as coral reefs and mangroves, which are vital for biodiversity and climate regulation. Key strategies for marine protection include establishing marine protected areas (MPAs), enforcing sustainable fishing practices, and reducing plastic waste. Organizations like the United Nations and various non-profits work globally to promote policies and raise awareness about the importance of preserving our oceans for future generations.
