1 Oceans By Ottilie and Carys

2 Plastic The main problem is plastic. Plastic, unlike other materials cannot be recycled .Instead, they dissolve into millions of micro-plastics, which is fatal to most fish. In a way, we are killing ourselves, as the micro-plastics kill small fish, which are then eaten by bigger fish, which are caught in our nets which we then eat. We are slowly, but surely destroying our home!

3 Plastic Island! The Great Pacific Garbage Patch is a collection of marine debris in the North Pacific Ocean. Marine debris is litter that ends up in oceans, seas, and other large bodies of water. The Great Pacific Garbage Patch, also known as the Pacific trash vortex, spans waters from the West Coast of North America to Japan. How much plastic is there on the Island ?-More than 4.8 million metric tonnes—that's about how much plastic waste gets dumped into the world's oceans from land each year. And this number is just a conservative estimate. Researchers believe the real amount could be as high as 12.7 million metric tonnes

5 Global Warming Global warming is caused by a phenomenon known as the greenhouse effect. A greenhouse (or glasshouse) is good for growing things because it traps heat inside and stays hotter than the atmosphere around it Earth's atmosphere behaves like a gigantic greenhouse, though it traps heat a different way. Gases high in the atmosphere, such as carbon dioxide , behave like a piece of curved glass wrapped around the planet. The Sun's rays pass straight through this greenhouse gas and warm up Earth. The warming planet gives off heat energy, which radiates out toward space. Some of this outgoing radiation does not pass through the atmosphere, but is reflected back down to Earth, effectively trapping heat and keeping the planet about 33 degrees hotter than it would otherwise be. This is called the natural greenhouse effect and it's a good thing. Without it, Earth would be much too cold to support the huge diversity of life that it does

6 Quiz 1.What causes the greenhouse effect? 2.How many metric tonnes of plastic are there on the plastic island? 3.When will there be more plastic than fish in the oceans?
