Paris said au revoir to cars. Air pollution maps reveal a dramatic change. Air pollution fell substantially as the city restricted car traffic and made way for parks and bike lanes.

“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.

En honor a la verdad El pasado 15 de abril, un tribunal de Moscú condenó a la periodista Antonina Favorskaya a cinco años y medio de prisión en una colonia penitenciaria por un delito de “extremismo”.&nb…

'Rusia contra el mundo' no es un libro ideológico. Trata de cómo se expande por el mundo un régimen de gángsteres, que instrumentaliza a terroristas y nos inunda con su propaganda. Agradecido de que así lo vean referentes de la izquierda como @lluisrabell.bsky.social.

NO, they did not "resurrect" the dire wolf (Aenocyon dirus).

They have only edited 14 genes of the gray wolf to resemble it. Apparently, all the changes are focused on its appearance (color, size and shape of the ears)

It is pure propaganda.

The Texas Girl Who Died From Measles Her father tells her story.

"The vaccination has stuff we don't trust," said the father of the 6-year-old girl who died from measles at the end of last month. Tom Bartlett visited with a family confronting an unthinkable tragedy:

I have covered presidential politics for 40 years. This was the most juvenile display by a President and Vice President I have ever seen. Other presidents treated their enemies with more respect. This is a low point and a dark day for the US. Totally embarrassing.
