Your answer is, The Rio Grande
<h3><u>
What is The Rio Grande?</u></h3>
The Rio Grande, known in Mexico as the Río Bravo del Norte and as the Río Bravo, is one of the principal rivers in the southwestern United States and in northern Mexico. The length of the Rio Grande is 1,896 miles and originates in south-central Colorado, in the United States, and flows to the Gulf of Mexico.
<h3><u>
How does The Rio Grande affect the environment?</u></h3>
A finite amount of water flows through the Rio Grande every year, so when there are shortages, every city along the river is affected. Due to climate change, hotter and drier seasons are reducing the snowpack that melts to feed the Rio Grande, and rising temperatures are increasing evaporation from the reservoirs.
Thus, <u>The Rio Grande</u> is your answer.
