Live in the sunshine, swim the sea, drink the wild air.
Earth provides enough to satisfy every man’s needs, but not every man’s greed.
I think having land and not ruining it is the most beautiful art that anybody could ever want.
Here is your country. Cherish these natural wonders, cherish the natural resources, cherish the history and romance as a sacred heritage, for your children and your children’s children. Do not let selfish men or greedy interests skin your country of its beauty, its riches or its romance.
