Greta Thunberg will one day be Mayor of London, of course she'll have to first convert to Islam. I hope she enacts a soccer ball kicking tax, one pound a kick, since kicking a soccer ball causes sweating, which in turn causes Global Warming and smog. Londoners are stark raving mad about soccer, so I believe they can kick their way to sustainability in no time. I see the United States enacting a similar 'baseball bat swinging tax' should Bernie Sanders or Al Gore make it into the Oval Office. Keep hope alive.
