iirc, algae are better oxygen producers per units of mass and volume, so a tank full of algae might actually be better than a tree. One issue though is that trees can grow on open ground, while algae require a tank to be built, most likely negating the economic benefits. Also, trees are more aesthetically pleasing.
Plenty of countries got into crosshairs due to the new wave of international propaganda.
Unfortunately, there aren’t that many ways to combat it under truly free speech, so many have chosen to outright ban various sources linked tto potentially malicious actors.
But once that is done, the gates are open. Now that plenty of governments have the power to ban whoever they deem bad, the freedom of press and democracy are under threat.
