“Air pollution fell substantially as Paris restricted car traffic and made way for parks, people-streets and bike-lanes.” Better for the climate, better for health, better for livability and quality of life. Common sense. Such a no-brainer, it’s remarkable that more cities HAVEN’T done the same.

Paris said au revoir to cars. Air pollution maps reveal a dramatic change.

Really appreciate that the iPhone Duo has an aspect ratio of 1:1.4 (or 1:sqrt(2)). Always appreciate DIN 476/ISO 216 which is just the perfect aspect ratio system for documents.

This idiot has probably never been to the BOREAL FOREST a day in his life. It is 5.5 times the size of Texas. You cannot "groom" it. It's burning because of climate change. The utter bullshit from these climate deniers. Canadians are sick of this bullying and they are not going to take it.

When using Microsoft Word or Google Docs, don't just make text bigger and bolder to make it a heading. That will work for sighted users, but screen reader users will miss that and just hear it as normal paragraph text. Use actual heading styles, like level 1 through 6.
