Don't erode nation's national monuments

Excerpts:

It's difficult to believe, but Congress initially refused to protect the Grand Canyon. Mining, lumber, railroad and other businesses were vehemently opposed to making the majestic gorge a park, and Congress continually failed to pass protective legislation.

But in 1906, Congress did pass the Antiquities Act, which allows the president to designate significant federal lands and waters as National Monuments entitled to permanent protection.
