Why the Trump/MAGA/GOP assault on facts? Because facts contradict every ideological policy they're trying to impose. Yes, #climate change is real. #Vaccines are effective and safe. It's the #guns. Trump economics is destroying jobs and the economy. Facts are powerful weapons against fascism.

Another #water fact. This one isn't fun, however. As much as a third of all food production today comes from unsustainable groundwater extraction —where groundwater is being used faster than it's being replenished. That cannot continue, but where is the replacement water going to come from??

Here's another fact about #water you may not know. More than 97% of Earth's water is saltwater — too salty to drink or use for agriculture.
