Initiatives to help save our oceans
Here are 20 significant initiatives focused on ensuring the sustainability of the ocean and marine ecosystems
|
Possible Topics for Inquiry
Climate Change: Rising sea temperatures and ocean acidification are affecting marine life and ecosystems. Plastic Pollution: Millions of tons of plastic waste end up in the oceans each year, harming marine life and ecosystems. (e.g. Great Pacific Garbage Patch) Overfishing: Unsustainable fishing practices deplete fish populations and disrupt marine food webs. (e.g. shark finning) Coral Bleaching: Increased water temperatures cause corals to expel the algae living in their tissues, leading to coral bleaching and death. Habitat Destruction: Coastal development, dredging, and bottom trawling destroy vital marine habitats like coral reefs, seagrass beds, and mangroves. Invasive Species: Non-native species introduced by human activities can outcompete and displace native marine species. (e.g. Crown-of-thorns starfish on the Great barrier Reef, green crabs) Pollution: Runoff from agriculture, industry, and urban areas introduces harmful chemicals and nutrients into the ocean, leading to issues like dead zones and harmful algal blooms. Ocean Noise: Increased noise from shipping, drilling, and other human activities disrupts marine life, particularly species that rely on sound for communication and navigation. Marine Debris: Abandoned fishing gear, shipwrecks, and other debris pose threats to marine life and navigation. (e.g. ghost nets) Ocean Acidification: The absorption of excess CO2 by the oceans leads to a decrease in pH levels, affecting marine organisms, particularly those with calcium carbonate shells or skeletons.
