Photosynthesis has a problem
The enzyme RuBisCO is essential for photosynthesis. But it kind of sucks at is job, and it’s getting worse with extreme heat.

The very bad math drying up the Colorado River

California and Arizona are currently fighting each other over water. But this isn’t new - it’s actually been going on for over 100 years. At one point, the states literally went to war about it. The problem comes down to some really bad math from 1922. To some extent, the crisis can be blamed on climate change. The West is in the middle of a once-in-a-millennium drought. As temperatures rise, t...

Lake Mead is America’s largest reservoir, supplying water for 25 million people across the southwest. It’s also drying up - a kind of poster child for the ongoing drought in the West.

    This is honestly the best chance we have at becoming a type 1 civilization. I think the complex mechanisms of living things along with their ease of use make it perfect for gathering energy more cost effectively than Solar

    So how is that not going to make a repeat of Great Oxygenation Event, except with sucking out CO2, out-competing every other life form and all the rest of the food chains relying on it?

      We've ruined a lot of habitats with relatively simple things, like farming, forestry, dams and irrigation - without directly intervening in biology of plants, only their habitat. This is going to wreak total havoc by comparison. Balancing ecosystems for our own survival needs most of that research to be regulated out of existence.

    Looks like Rubisco is a failsafe for too many intelligent mammals messing over the planet . More mammals consume more resources , creating more C02 which traps more heat - plants make less food - mammals starve and die, population decreases ,lowering demand for resources , reducing C02. Plants clean up CO2 to put the planet back in balance.

    Hysteria. We’ve always had flooding. The Netherlands are under sea level too. The problem is the pumps - the contractors did substandard work.

It wasn’t levy failures, it was Congress refusing to act while the Corp ducked the mess it made.
