"President Barack Obama will use his executive powers to protect more mountains, rivers and forests from development if Congress does not act to preserve such wild spaces, the U.S. Interior Secretary said on Thursday."
"Portions of the Grand Canyon, Redwood forests in California and Caribbean seascapes have been protected under the 1906 Antiquities Act, which gives the president broad authority to put natural terrain and historic sites under federal protection.
Such preservation efforts can also come through Congress but presidents in a second term have typically felt freer to designate such spaces unilaterally.
On Thursday, Interior Secretary Sally Jewell said that the president was ready to move ahead."
