Marine conservation groups are organizations dedicated to protecting ocean ecosystems and marine life. They work to address issues such as overfishing, pollution, and habitat destruction. These groups often engage in research, advocacy, and education to promote sustainable practices and raise awareness about the importance of healthy oceans. Many marine conservation groups collaborate with governments, local communities, and other stakeholders to create marine protected areas and enforce regulations. They may also conduct campaigns to reduce plastic waste and promote responsible tourism. Notable examples include Oceana, The Ocean Conservancy, and WWF's Marine Program.
