In the united states the main commercial option for non-lithium batteries is Nant who is developing zinc-air batteries (but for usage alongside lithium)

Farmed insects live their full lifespan as opposed to larger animals which only live around ten percent on average.

I personally do not advocate anyone to eat plant-based meats because of the harmful effects on health (this coming anecdotally from myself after eating them for 2+ years). The phytates in almost all grains / legumes / beans bind to almost all free zinc copper and iron which has a very negative effect on health.

Insects (similar to ruminants) are able to naturally assimilate the high protein foods and filter out the phytates. Eating a half-pound per day of insects helped me to greatly recover my health after following a vegan diet for almost three years.

These can also be interpreted as the number of strings of parentheses with n matching pairs

So P(2) would be (()) and ()()

Surely there is a bijective map between P and T somewhere in there
