Yes, there are tons of recipes for oatmeals, overnight oats or baked oats. Enjoy trying them out! :)

Oats and nuts maybe? They’re filling and will last you quite some time.

There is indeed an upper limit for global warming, because hot bodies lose more energy by radiating heat than colder ones. I think the equilibrium of energy gained by the sun and lost by heat radiation from the earth is at something like +5K in average global temperature. I doubt humanity would survive this though, civilization definitely won’t.

This and we are gonna have replaceable batteries in the future as well. Thanks EU!

Some of these points are not inherent properties of cryptos, like the environmental impact and the transaction overhead.
