Water on Earth travels freely, without regard to borders, but it's not evenly distributed around the world, and that distribution is changing as climate changes.
Free of countries’ borders, our planet’s water goes where it wants. This seems obvious, but many of us don’t give much thought to the transport of this vital resource that makes life possible. Because we do not have control over weather that brings global water deliveries, we try to manipulate water resources once they are on, or under, the ground. Problems arise when we limit our focus to our immediate needs (time), and the needs of our local area (place).
