Explore these resources to teach students about marine organisms, their relationship with one another, and with their environment. Marine pollution from chemicals, oil spills and radioactivity has been a high-profile issue since the Torrey Canyon oil tanker was shipwrecked on the UK coast in 1967. In our ocean, these chemical additives can leach into surrounding waters—posing another potential chemical threat to marine life. Sometimes chemicals are dumped at sea. This comprehensive guide describes the organisms and ecosystems of the Great Barrier Reef, as well as the biological, chemical and physical processes that influence them. Each year on two far-flung Australian islands, more than half a million hermit crabs die after becoming trapped inside our plastic waste. What You Need to Know About Ocean Acidification. When we burn fossil fuels, we don’t pollute just the air but the oceans, too. There are concerns about exactly how these chemicals, that are now mixing together in rivers and oceans, are affecting marine environments and little is known about the effect this may have in humans.
