This recently published study suggests vitD supplements alone provide some protection, even for acute cases. It’s a small sample population (n=75) and a pre-print, but it looks convincing to me (non-scientist, non-medical professional):

“Of 50 patients treated with calcifediol, one required admission to the ICU (2%), while of 26 untreated patients, 13 required admission... Of the patients treated with calcifediol, none died, and all were discharged, without complications. The 13 patients not treated with calcifediol, who were not admitted to the ICU, were discharged. Of the 13 patients admitted to the ICU, two died and the remaining 11 were discharged.”

This is an all-of-the-above-all-hands-on-deck moment in human history, so I applaud you for focusing on the things you feel are most impactful.

Some of us are also looking beyond the challenges (e.g., coal power) that have known solutions for the most impactful thing we can do to buy more time. Large transportation, electricity, and agricultural infrastructure will take time and lots of political will to change.

Planting trees on unproductive land with desalinated ocean water that no one's fighting over is low-hanging fruit.

In addition to capturing carbon, forests (of native tree species) provide many ecosystem services, including fresh water retention in the land, food and habitat for other species, shading of the ground, etc that a greenhouse full of algae would be challenged to provide. Most of the carbon stored in a forest is subterranean and increases significantly over time.
