This was received from Suzanne Ku, a year ten student at Christmas Island District High School, Christmas Island, The Indian Ocean, Western Australia.
Since 1999, the year ten students have been involved in the Greta Beach Marine Debris Survey.
"This survey is organised to clean up our beach as well as protecting the endangered green turtles (Chelonia mydas). Their survival is threatened due to the amount of litter washed ashore on Greta Beach. The turtles become snared in fishing line, nets or ropes. Some might mistake plastic bags for jellyfish therefore starving from a false feeling of fullness.
The students are divided into five transect groups. Each group collects, sorts and counts the different pieces of debris in their own transect. They are then deposited into different marked bags and weighed. In past years, burning was the only solution to disposing the rubbish. In the latest survey on April 10, 2002, the debris collected was carted out.
Here are the results of our surveys:
| Clean Ups | Number of Pieces | Weight (kg) |
| May 1999 | 11,155 | 251.05 |
| September 1999 | 10,330 | 263.65 |
| May 2000 | 8,039 | 261 |
| September 2000 | 22,346 | 458 |
| June 2001 | 2,888 | 73.25 |
| September 2001 | 3,445 | 109.8 |
| April 2002 | 4,818 | 86.5 |
Here is what we found:
| Material | Percent |
| Plastic | 47 |
| Rubber | 38 |
| Rope | 12 |
| Glass | 3 |
| Metal | 0 |
Thanks Suzanne! Canadians are also actively involved in helping to clean our shores - lakes, rivers, oceans - and doing their part in keeping the world's water clean and protecting wildlife.
