Encouragement of higher education for our youth is critical to the success of our collective future.

The War Powers Act requires presidents to seek the consent of the American people, through their representatives, before sending our troops into war. It is the responsibility of Congress to deliberate and consult with the executive branch before involving ourselves in a military conflict.

Since January 2003, at the height of the debate on the possible unilateral strike against Iraq, I have advocated for a reinstatement of the military draft to ensure a more equitable representation of people making sacrifices in wars in which the United States is engaged.

Photosynthetic organisms in the sea yield most of the oxygen in the atmosphere, take up and store vast amounts of carbon dioxide, shape planetary chemistry, and hold the planet steady.
