Beach clean up project

By-Roshan mistry 8F


Hi, My name is Roshan Mistry and i am in the island school community. i am writing this report on micro rubbish and macro rubbish. I will also need to come up with some idears that can help not only one beach but many more in Hong Kong. On the 16th of January year 8 went on to Discovery bay south plaza beach (san pak wan)to clean the beach. Separating the macro waste (more than 1cm) and the micro waste (less than 1 cm). A company called plastic free seas. Free seas spoke about what the effects on littering and where it all ends up and how it affects creatures living in and out of the sea.

The beach was spit up into 8 equal section and each class had one section of the beach to clean up. There was 3 categories collecting macro collecting micro and categorizing and counting all the waste. In every section had a 1M squared square and in that square we tried to find micro waste like things smaller then 1cm. The group that was categorizing the rubbish had to tally it as the went on. They had a data sheet to help them if they didn't know what was what. I think our whole year did a great job, we all collected 55KG all together. In each group there were 4-5 people that needed to collect as much macro waste as possible.

Data analysis- Results and graphs (micro waste)

Most of the micro waste comes from factory tunnels, which leads to the sea and that where all the rubbish lands. There are 5 huge patches in the water. Those are full of rubbish every year they get bigger and bigger. There were lots of BB gun pallets plastic pallets and much more. There was hardly any metal. Mostly what we found on the beach was polystyrene and plastic pellets.

Sea animals and land animals cant tell the difference between plastic and their normal food. Lots of animals die every year because of the amount of plastic that they have ate. It also affects us because when we eat sometimes we don't know whats in the food. About 100,000 marine creatures die each year from just eating plastic.

Macro waste

This graph shows that the material that was most collected was polystyrene and the least collected was straws and cutlery. Some of the waste we found on the beach came from china. We found this out because some of them were not being sold around shops. Another one of our findings was that plastic packaging was found all over the beach.Lots of these products end up in the sea because of oil tankers or mainly people just throwing things away anywhere . Also when storms come in lots of the rubbish gets thrown in to the sea.

Sometimes lots of the products come from other close countries like Taiwan, Beijing and other places. For example pollution comes from Beijing because of all the factories that they have. In the past few years Chinese bottle has ended up in our beaches and through research we found that they have come from China.

This creates huge problems for the sea animals because when we throw our waste away it goes in the sewage and ends up in the sea and sea creatures think that it's there food also when people eat sea food they must be careful because there might be plastic in the animals bodies. More than 100,000 animals die every year through ingesting and or becoming entangled in nets, plastic bag and etc.
