How marine conservation connects marine life

Marine conservation is the protection and preservation of ocean and sea ecosystems through planned management to prevent overuse of marine resources, limit human-caused damage, restore damaged ecosystems, and preserve vulnerable species and ecosystems. These lessons answer how marine life is interconnected and how understanding those connections helps make sense of conservation challenges. They follow the links between species, ecosystems, and human activity.

   Overfishing can contribute to overabundance by eliminating an ecosystem's natural predator. This disrupts the natural food chain and allows species to grow without regulation. A tank of ballast water is estimated to contain around 3,000 non-native species. Hull biofouling and dumping ballast water or water from marine aquaria can move organisms beyond their native ranges, allowing non-native species to disperse into new environments and disrupt established ecosystems. Marine conservation is urgent because up to 88% of coral reefs in Southeast Asia are now threatened, with 50% of those reefs at either "high" or "very high" risk of disappearing. This especially harms people in Samoa, Indonesia, and the Philippines, where many depend on coral reef ecosystems to feed their families and make a living.

   Ghost gear, lost, discarded or abandoned fishing gear, can keep "ghost fishing" in marine ecosystems. Drifting through the water or lying on the seafloor, it can trap and entangle animals when no human is operating it.
