Boyan Slat & The Ocean cleanup -- Mashiro Yamashita
I thought Slat’s project should be done. In fact, the machine can collect a lot of plastic trash. According to hid TED talk, 300 million tons of plastic is producing every year, so we should collect plastic which were already thrown away into the ocean. Despite this situation, there is a criticism that, firstly, we should reduce the amount of producing plastic. It is correct, but I think we should do both of them which are reducing the amount of plastic produced and collecting plastic trash. Some critics say that the plan will have a bad effect on creatures of the sea. However, I found that the project will save them by reducing plastic trash. He used crowdfunding to raise fund, so we can know that he has a character which can influence others. People raised fund because they were probably moved by his speech or thinking.
