Disappearing Rio Grande

Texas Tribune
The Rio Grande is disappearing. Demand for water is growing as average temperatures rise faster than they ever have in the past 11,000 years. The water that remains is being fought over by the countries and states that agreed to share the river. At the same time, a border fence is being built along its banks.
