Why are water and timber resources in the United States in need of responsible management

Because of all the clear cutting, pollution, and groundwater depletion.

Water and timber resources in the United States are in need of responsible management because they're on the verge of causing irrevocable hazards to the regional environment.

Explanation:

The forests in the United States are being cleared at a whooping rate owing to the increasing demand for timber wood. This has resulted in the emergence of serious environmental hazards like rapid soil erosion, migration of the wildlife to forests elsewhere. The average domestic water consumption in the United States is 400 gallons per day. This way more than the average daily water consumption elsewhere in the world. Thus the water and timber resources in the United States need to be managed responsibly.
