ExxonMobil, Royal Dutch Shell, BP, Chevron Corporation, ConocoPhillips, and Total S.A. They are all responsible for ruining our beautiful planet while they should start to build air purification equipments.
Stop running your fossil fuel vehicles and machinery. Let everyone pay heavy taxes. From these taxes, you should start to build air purifying systems. Every country should pass a law: zero emissions! Right now!
Otherwise, the whole economy will get lost. There will be nothing more left. Your planetoid will be destroyed.
