Metalenses are a relatively fringe optical technology — at least, they were. Until now, it has been largely pursued by startups and scientists but that is changing as Canon has jumped into the fray and not only makes them but also produces the equipment necessary to manufacture them.
I think we need to address the problem by preventing companies from externalizing their costs. If they had to pay exactly as much as it cost to clean up the pollution they emit then they will actually internalize that cost and have financial incentives to decrease pollution. I am obviously oversimplifyng since the cost is not constant and this would create a financial incentive to create companies that remove/ filter pollutants more effectively and efficiently.
It’s complicated because it requires international agreements but it’s a more realistic approach than thinking companies should do it because we need them to.
Hell yeah!
Great point. The WTO has been effective at enforcing international trade agreements.
Most of their enforcement has been things like forcing countries to import tuna caught with dolphin- killing nets and other messed up stuff… … but they could totally enforce a carbon & pollution fee system for internationally traded goods.
Being that they are essentially run by international conglomerates, I doubt they will, but they are positioned to.
