Compared to the Universe were are not that big. But even our home planet isn’t that big. Even our small layer of atmosphere isn’t that big. Even the amount of drinkable water and agricultural land isn’t that big.

So we should take a LOT of care to keep our tiny niche in the universe in order and clean. It will take a long time till we discover a new place as good as this one.
