In recent years, the problem of marine pollution has become more and more serious. Plastic particles that are harmful to organisms will not only cause the death of marine organisms, but also affect terrestrial ecology due to biological amplification. What's more, the process of decomposing plastic particles will aggravate global warming. In order to conserve and sustainably use the ocean and marine resources, we have designed a machine "Heart of Ocean", hoping to collect plastic particles in the ocean through several bionic designs that are friendly to the environment and solve the harm caused by plastic particles.
