The rate at which we are generating, consuming and disposing a non-bio degradable substance aka Plastic – it would spawn a new kind of fictional hero or at least add a new task to already created fictional superheroes.
Circa 1990 – Superman/ Spiderman rescues the world from the bad guy(s)
In the future the super hero would not only be fighting evil folks . He / she would be swooping in on the Pacific garbage patch and similar heaps of non-biodegradable , earth polluting material and flinging them into outer space. All the superheroes would need to team up to clear up the plastic choking the planet.
The superheroes like Superman/Spiderman are fictional . The plastic on the planet is real . We need billions of people to become eco heros by making sustainable , responsible choices. At this point in time there is no answer in terms of solutions to bio degrade the plastic that is choking land and sea. The least we can do is to reduce the rate of addition to the pile.
