Who said a ship or grinding up the plastic was the best way to ameliorate the problem? Did oceanographic, environmental, or engineering experts say that?
Why aren't we asking about microbiologists genetically engineering microbes to eat the plastic (been done, I think)? Or nets to catch it (also done)? Or...?
Nets have been tried but the collection of trash in this manner did not prove to be cost effective or a good method. They had great difficulty removing the trash from the nets. Using microbes that are effective is a new science and has not been used as of yet. Also there is so much trash that it will take time for this method to be effective. A trash ship would be very effective. Read entry above , it seems it has been invented by the Dutch.
Someone is working on a pipe like device the can suck plastic debris up.
The grinding process is preferred because of the abilty to use less space to store the material.As I understand the process it would require several ships one to grind the material and the others to haul the waste away.
Probably because the huge uncaring for our planet population overwhelmingly trump's technology's abilities without humans stepping up to become responsible n pro active to our Earth. ?
Once again it seems the profit motive prohibits a common sense solution to a world wide problem.Surely we could design a ship with the tools to grind up this plastic and thus remove it from our waters.I guess it just would not be profitable and the governments are to cheap to do so.
An enzyme has been inadvertently developed that consumes plastic. Sounds good in print but I would wonder what else it might consume or what long or short-term aftereffect may develop.
