Question: Do you think the world will look brown in space from plastic in 30 years?

I really hope not. Though it is unlikely as I don’t think there is enough plastic to do that. It is more likely to look brown and blue, the blue from the oceans and the brown/sand colour from scorched desert earth is we don’t do something about climate change soon. This is a very unlikely outcome though in 30 years, to scorch the earth through climate change would take about 150-200 years if we keep going at the current rate. We are currently at a very important time in regards to it, if we don’t do something NOW, then we will become a brown ball, and not a blue and green ball 🙁
