Sustainable transportation – carry it. The New World never discovered the wheel.
Sustainable communication – shout.
Sustainable agriculture – Never happened. Humans always reproduce themselves beyond their food supply.
Sustainable energy – human slave labor. Fantastic historical precident from Egypt and Jews to Rome to the Triangle Trade to US South to Russia. Human slavery really hung on tight in Russia. 6th to 10th centuries AD Slavonic peoples were captured by Khazars, Kypchaks, and other Steppe peoples and sold in Crimean markets, hence “slave.”
Enviro-whinerism is Luddism. The Enviro-whiner trinity is “expensive, shoddy, deadly.” Shoddy was the first recycled wool. Look it up! How well do you suppose that worked out? NOTHING is sustainable. The Second Law of Thermodynamics cannot be evaded or perverted.
Conservation: somebody else in the future deserves to consume it; and not them, either.
