Which statement most accurately combines and summarizes the information from the ""plastics"" article and the ""what we know about: plastic marine debris"" brochure about how plastics break down?

The statement which most accurately combines and summarizes the information from the "Plastics" article and "What We Know About: Plastic Marine Debris" brochure about how plastic break down is as follow:

Once plastic reaches the ocean, it does not go away or mineralize, and it degrades at a slower rate because of the cold water. As plastic breaks down, the pieces get smaller and smaller, turning into micro-plastics, which are smaller than 5 mm.

Explanation:

The above statement fully describe the way plastic breaks down in ocean or sea. As the plastic doesn't degrade at a normal speed due to the coldness of water. When it breaks down then it is converted into small pieces of size smaller then even 5 mm which has become a real threat for marine life and human beings. We are eating these micro-plastics as when we eat fish and other marine food.
