"Learn from the birds what food the thickets yield;
Learn from the beasts the physic of the field;
The arts of building from the bee receive;
Learn of the mole to plow, the worm to weave."
Sustainability comes in many shapes and sizes, small things like turning your light off when you leave or large things like making sure the hazardous chemicals you used in chemistry were disposed of properly. As we've alluded to in previous LibGuides, leaders should not treat the world like a garbage bin, whether that means its people, its animals, its plants, or its atmosphere. Use your own position as a leader in society to be a catalyst in changing the world.
We are the ones in charge of the world, so don't dismiss the size your impact could be. Whether you lower your technology use, or make your community more efficient, or simply better the conditions around you, work towards a cleaner and more sustainable future.
