How do scientists know where the natural resources are without digging?

The Earth’s natural resources include air, water, soil, minerals, plants, and animals. Conservation is the practice of caring for these resources so all living things can benefit from them now and in the future. Ninety-seven percent of Earth’s water is salty ocean water and another two percent is trapped in Earth’s ice caps and glaciers. The precious one percent that remains must be used wisely. Drip irrigation, seen here in action on an Israeli farm, can cut agricultural water demand by seventy percent—yet it’s used on only 2 percent of the planet’s irrigated cropland.
