An increasingly large danger to our oceans is the killing of large predators. Ocean ecosystems depend on large predators, like sharks, for a stable balance of life. According to some estimates, 100 million sharks may be killed annually, mostly to feed China’s demand for shark fin soup. For these reasons, I chose to include shark finning as a top 8 danger to ocean life.
I chose to include over fishing because it disrupts the balance of life in the ocean and has significant consequences for the millions of people worldwide that rely on fish as their primary source of protein. Only through responsible fishing will we be able to preserve life throughout the ocean and consequently on land.
What are ocean dead zones? They are areas in the ocean that have excessive nutrient pollution, caused by humans. For this reason, there is a lack of oxygen causing many species to die out. I chose to include ocean dead zones because they are an imperative issue that our oceans are facing and the problem is rising!
Coral reefs contain some of the largest diversity of life in the world. They are home to thousands of different plants and animals. I chose to include coral reefs because they've been in danger for years! They are slowly dying out and it's predicted that nearly 90% of the world's coral reefs will die by 2050!

Ocean acidification involves the lowering of the oceans's pH levels as a result of excesss atmospheric carbon dioxide. Much like global warming is occuring on land, ocean acidifcation is occuring underwater although harder to see. I chose to include ocean acidification as a top 8 danger because it's one that we don't always focus on, because we aren't directly affected by it. Click the link to find out more!
An oil spill occurs when liquid petroleum hydrocarbon is released into our oceans. I chose to include oil pollution as a highly rated danger to our oceans because of the damage that they cause to marine life. Each time that oil is spilled in our oceans marine mammals are affected and it's costly to effectively clean up.
I chose to include ocean pollution because on average 14 billion pounds of trash is dumped into our oceans each year. Nearly 80% of that garbage comes from land. Let's do our part to help protect ocean animals by recycling and cleaning up after ourselves!
I chose to include mercury pollution because it is one of those most harmful pollutants facing ocean animals today. Mercury pollution comes from coal burning power plants across the country that dump toxic mercury into lakes, rivers, and forests--all sources that eventually lead to the ocean.
