Over increasingly large areas of the United States, spring now comes unheralded by the return of the birds, and the early mornings are strangely silent where once they were filled with the beauty of bird song.
Rachel Carson
Man has gone to
Man has gone to the moon but he does not yet know how to make a flame tree or a bird song. Let us keep our dear countries free from irreversible mistakes which would lead us in the future to long for those same birds and trees. Felix Houphouet-Boigny
