In this essay we will discuss how climate change effects the ocean from the wildlife that it occurs to the vital resources it provides to every inhabitant on the planet, for example it provides 50% of the oxygen on the earth and 97% of the drinking water. The air you breathe, water you drink, the food you eat all come from the ocean. However due to climate change, the ocean and its wildlife are in an extremely vulnerable state due to human activity. In the past four decades, marine species have declined by 49%. Sea levels have risen 17 centimetres in the last century due to climate change. Rainfall and tropical storms have increased and will be more frequent.  These are briefly some of the many effects Climate Change has on our seas.

Climate change and the littering of our oceans has a wide and damaging effect on ocean and marine life. Litter affects our marine wildlife to a huge extent. Human-made items are thought to make up 49% of all marine debris according to a recent study by the National Oceanic and Atmospheric Administration. An estimated 100,000 marine mammals and turtles are killed by plastic litter every year around the world. Large marine animals such as seals and dolphins can starve to death when muzzled by plastic litter. Plastic is also eaten. In Los Angeles alone, 10 metric tonnes of plastic fragments from e.g. shopping bag and soda bottles appear on their shores. Over the last 10 years we have produced more plastic than the last century.

In conclusion we need to take action in helping our planet to retain its safe healthy form. The way we to do this would include cutting down on the overall use of plastic. This will limit the impact it has on marine life and lower the fatalities of the fish population. Always clear up after yourself on the beach and go even further by participating in local beach clean ups. To try to help stop climate change and the effects of global warming we could try walking, use less cars, save electricity and plant more trees to absorb CO2. Above all the best way to make a change is to educate others, consider patronizing restaurants and grocery stores that use less plastic.
