Never Leave!

(current project)

(CNN News)-Microplastics have been found in human stools for the first time, suggesting they may be widespread in our food chain.


Industrial products (e.g., plastics and batteries) bring huge convenience to our life.  However, have we ever seriously thought about these questions: where do they go to after they finish their service? Is the trash can the true end of their life? Do you pretend that they have left your world after throwing them away?

Actually, they never leave! They are everywhere! They threaten the wildlife and our pets who do not recognize them. They come back to us through polluted water, vegetables, and animal meat that grow on this polluted land. No matter how hard it is, they have found a way to our gut!

Every year, over 300 million tons of plastics are produced and more than 50% of them are discarded. Plastics have been found in the most remote areas of the ocean, including the Arctic and Marina Trench. To save us, our next generations, and our planet, it is now the time to look seriously at them and take action!
