Hi Guilherme,
From this TED article, it seems the original material used to made plastic is environmentally friendly but subsequently, synthetic material is used to make plastic which is harmful to the environment We may have to go back nature, to find the solution.

I like your idea about a think tank. Maybe a virtual global think tank is more inclusive (e.g using social media).

With awe and respect,
