If you eat just rabbits, nothing else, just lean rabbit meat you will starve to death

It doesn't matter if you eat 2000 or 10000 kcal of rabbit, if you don't get more nutritious food, you will die of starvation and your body will waste away.

More calories by itself isn't a good thing.

CO2 also lowers nutrient density despite increasing total size and weight of crops, meaning you have fewer nutrients per calorie and per pound. Even if you could spin this into a positive, all crops have the same vulnerabilities to heat stress, drought, and unpredictable seasons, all of which are increased by excess CO2.

Even with crispr changing the timeline to create new crops that might handle the new climate every year to be incredibly short, theres not enough time to produce and distribute those new versions before the climate has changed enough to require yet newer versions of said crops.

But good news, bugs and algae will be plentiful. hope you like algae bars with insect protein bars as a snack.
