I thinking as they are taken out of the equation (and world), not just fabricating what needs to happen indoors. How else do insects and pollen affect the world? Bugs and animals (and plants) up the food chain eat those insects. Bees collect pollen.
We can pave over the planet and live underground but that will leave a barren wasteland.
Just let the surface law fallow and move all of humanity underground. Ultimate environmental policy.
