Sydney, Australia plans to mobilize all the people to collect marine garbage data

according to Taiwan's "united" on July 9, Sydney, Australia launched the global citizen science program, calling on students and volunteers to calculate and record part of the 5trillion pieces of plastic garbage in the sea

"Australian microplastics assessment program" (ausmap) will train volunteers to collect plastic waste of all sizes along the Australian coastline. Michelle blewitt, the director of the plan, said that the goal of the plan was to monitor the amount, location and source of plastic waste in the marine environment

she said: "at present, it is estimated that there are 5trillion pieces of plastic garbage in the sea, but there are only 3trillion trees in the world, and there are more plastic garbage in the sea than on land." Plastic may not only entangle animals, but also become animal food. For example, plankton at the bottom of the food chain will eat small plastic garbage

according to the Australian Broadcasting Corporation, students aged 9 to 12 who participate in the program to improve the quality of products use rigorous scientific methods to collect coastal data. Bluitt explained that they have two ways. The first is to collect large-scale plastic waste, such as plastic bottles and bags, which will be entered into the Australian marine waste activity database

the second is to collect 1-5 mm small plastic waste. They will first collect the top 2 cm sand of the sample, and then filter it according to the sieves of different sizes. Finally, the remaining small plastic will be checked, calculated and quantified

ausmap will also establish local centers and provide relevant equipment for the use of the whole people. Bluyt said that the purpose of this plan is to invite Australian people to participate, because the more actively people participate in the project, the more likely it is to avoid plastic waste falling into the sea

Harriet spark, a volunteer who loves snorkeling, said that she is a diving coach and often snorkels with her colleagues on the beach. They were surprised to find a large number of straws on the shore, so they came up with the idea of picking up plastic straws to let everyone know the meaning behind it

spack launched the "straw campaign" to encourage volunteers to collect straw garbage while snorkeling in manly cove. "We collect straws every weekend and calculate the quantity, and use these data to persuade enterprises to change the practice of using straws and plastics," she said During the summer holidays from 2017 to 2018, they collected more than 2500 straws

It is usually applicable to the realization of the predetermined tolerance of the cylindrical surface

spack points out that people can refuse to use straws to avoid distorting the later detection experimental data, but if enterprises refuse to use straws, many straws can be reduced, and then these straws will not appear in garbage dumps, dustbins or oceans
