Crops can blight, animals can get diseases. I don’t know much about hydroponics but I know that bacteria are a concern. What food source is the most reliable, the least likely to produce less food than expected?
The things that cause famines are lack of diversity.
Cells in agar in an incubator. Anything above that scale is bound to have losses and fails. How much depend on how controlled your environment is.
Anything living can get diseases. I’d still go for crops grown in a controlled, indoor environment.
There’s a way to grow bacteria on natural gas if you don’t have grow lights, and they used it to make fish feed for at least a while, as well as some lab work on electricity-eating bacteria. If you don’t care about your liver I guess this drink is also technically a source of calories with no biological production needed.
Diversity is the most stable plan. Don’t put all your eggs in one basket. Get food from multiple sources.
Chicken eggs
Fish eggs
Duck eggs
Goose eggs
Quail eggs
Platypus eggs

Profit
Seize people’s grass lawns and tear out 2/3 of roadways and convert the land into community gardens and ponds, grow food where the people are. Probably some form of population control.
Pie in the sky though. We’ll probably just start eating bugs by the container ship load and then go extinct instead
That’s not going to be as much land as you think it is, relative to the food needs of the maybe billion people living in lawn-growing places.
No you’re right, but it would be one of the more difficult things to convince people to do, so in this pie in the sky scenario where people actually give a crap about anything they’d also be doing a lot of other stuff that together would make a larger whole.
Oh yeah, not to say that lawns make sense. It’s just not a silver bullet.
