Meh. The climate strike is mostly just for those Westerners infected by panic-Greta's panic-attack. Nobody knows what global warming will bring, so no reason for panic. Anyway,  even if Europe & the US will bring down their emissions, China, India & other 3rd World nations will more than make up for it. 

& what I did? Instead of taking the bike, I walked downtown (to buy a new inner tube for my bike, so I can use it again). 
Hmm, considering that it is more exhausting to walk than to cycle, & therefore I exhaled more CO2, I actually made the situation worse. Silly me...
