Plants do a great job of converting CO2 into O2. ;)

Pretty cool proving the concept works under Martian conditions.

And all other things being equal plants do better with more CO2, which makes it not at all clear that increasing CO2 in Earths atmosphere is bad for us.

Few want to talk about this Natch.

One reason for more CO2 is because we're killing off plant life to raise cattle and build concrete canyons.

I am still detecting almost no interest. Part of this is because the Revolution is stomping on any happy news about America because that gets in the way of their narrative that America is so terrible that it must be burned to the ground, right now, there will be no quibbling about it.

But I think a part of it is that almost no one cares, this has nothing to do with our lives, which are turning to shit rapidly.

Many people seem more concerned about the size of Kim Karchrashian's arse and other bullshit.

In Holland, flower growers typically have concentrations of 900 ppm in greenhouses.

I was watching a show the other day that said trees don't really begin collecting carbon until they get older. Several decades. That means even if we were to plant millions of trees right now, they would not begin to help with climate change until nearly 2050. That is, of course, exactly what we should do, but it is frustrating to know that the process takes so long.

Apparently, they emit as much carbon as they store while they are developing young trees.

Darn science and reality stuff again.

Good point. It's also important to remember matters of scale. Algae also converts CO2 to 02. Algae produces 75% of O2 for us to breath....and we're killing it off with "red tides", pollution, etc. The whole killing off reefs problem is related.

Microalgae, also called phytoplankton by biologists, are very small plant-like organisms between 1-50 micrometres in diameter without roots or leaves. Together with the seaweeds (macroalgae or large aquatic plants), microalgae are part of the so-called aquatic biomass. Microalgae are very common (hundreds of thousands species exist) and occur both in freshwater and seawater where they form the basis for most food chains. Most species contain chlorophyll, use sunlight as an energy source and convert carbon dioxide (CO2) into biomass. In this process of photosynthesis the algae produce oxygen (O2). On a global scale microalgae produce more than 75% of the oxygen required for animals and humans.
