Water Distribution on Earth

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

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