This is interesting — a recent study of mode share (the % share of transportation trips by car, transit, walking, biking etc) relative to city size and income levels in almost 800 cities in 61 countries. Interesting results. HT @davidzipper.bsky.social

Yesterday evening I left the EU Parliament at 19:30, after a very long day.
Good news is that members of 4 parties are unhappy about the CAP proposal, so there's a potential openness for discussion.
The bad news is that the overall spirit on environment is rather 'slash-and-burn'. Quite alarming.

I used to think that it's especially in the "developed" world (Europe, N America, Australia etc) that people have devestated nature. But the Andes all around Cusco have hardly any traces of natural vegetation, apparently since Inka times.
So it's not "colonialism", it's rather imperialism here.
