This is very positive for millions of Americans.

Places that Americans love like Florida's coral reefs and the alpine meadows of the Rocky Mountains could suffer greatly from global warming, according to the report.

Americans are optimists. They hope they'll be wealthy someday - and they're positive they can get one more brushful of paint out of an empty can.

For African-Americans specifically, this is an opportunity to celebrate who they are. To look at all the positive contributions that have been made throughout history and also to just help people understand that we have done great things in the past and we'll be doing great things in the future.

These efforts are positive steps to promoting healthier lifestyle choices for Americans. It is extremely appropriate that President Bush launched this initiative in a workplace setting. More and more employers have made the connection between better health and lower health care costs, and are taking positive steps to enhance employee wellness programs.

I'm a very positive person and I just wish everybody else would be positive.
