What should we do? Voltaire said: “Cultivate your garden.” Let’s start a movement: Voltaire for restoration.
"Il faut cultiver notre jardin" is a powerful metaphor. Voltaire must have meant it to be applied much more widely than to gardening alone. However, paying attention to, restoring, and even augmenting the beauty we have been born into would be a good starting point on the road back to a fully healthy biosphere.
