I've always been a big fan of the oceans. That's why I've been always worried about them.
One thing I've felt sad about has been how people are talking about greenhouse gas emissions so much, they think it as the only thing regarding environmental friendliness. We've seen people talking about how issue X affects the CO2 emissions, but won't care at all about the freaking huge amounts of plastic in the oceans or the coral reefs dying.
I'm happy there are quite many great projects aiming to remove loads of plastic from the oceans.
