Choose the answer that best explains one reason why conservation of freshwater is

important.

• Freshwater should be conserved because it can be found in large quantities on Earth.

• Freshwater should be conserved because it is limited to Earth's oceans

• Freshwater should be conserved because it is the only water that can be consumed by humans.
