Marine Polution

Chemicals dumping, species dying. You can help.

Dead zones and Garbage patches

So much trash is dumped into the ocean that it creates giant swirling patches of garbage. Nothing lives around these areas because anything that does will eat trash and die. There are millions of garbage patches across the ocean including the biggest patch known, the Pacific Trash Vortex.

Dead zones are also extremely common in Earth's water. Dead zones form when trash and chemicals are dumped into the ocean. These chemicals form algae which takes in all of the oxygen around it. Nothing can live here either because no oxygen is available for organisms to live. 400 dead zones are known in the world, and many more haven't been found.

Chemical and Trash Dumping

80% of all marine pollution comes from activities on the land, and 80% of all of that dumping goes untreated. Most waste dumped into the ocean is consumed by marine life and birds, killing them. Nets cut away by fishermen trap and ensnare many organisms, and they starve or choke to death. Environments can be destroyed by toxins released by chemical sediments. This is a big problem and if it continues most marine animals and ecosystems will become extinct in as little as ten years.

Radioactivity and Chemical Side-Effects

Most chemicals dumped into the ocean are radioactive. Animals in the ocean are often greatly affected by these chemicals. Almost every marine organism is infected by man-made chemicals. In fact animals high up in the food chain can have contamination levels up to three billion times their environment. People who eat these contaminated organisms also become contaminated.

Many of the man-made chemicals dumped into the ocean have devastating effects on marine life. Habitat destruction is limiting the space available for fish and mammals. Chemicals in the ocean cause diseases such as cancer, immune system damage, and behavioral problems. These side-effects can be passed to humans when consumed.

How to help

A cleaner ocean will help marine life and humans too. A clean ocean means we can keep using it for swimming and other activities.

There are many things you can do to help reduce marine pollution. Some examples are organizing beach clean-ups, reducing trash, checking what you put down sink drains, and taking care of a local lake or stream.

All of these steps will help save marine life, make our ocean cleaner, and keep our beaches safe to use.
