Mexico's Armando Fuentes Aguirre -- Cáton -- 

contrasts the UK's treatment of the River Thames with his country's abuse of its rivers!

Here's a translated snippet from  a recent radio broadcast:

"The Thames River flows these days fresh and clear.

"Fishermen with the endless patience required of them line it's banks.

"There are no less than 80 varieties of fish in its waters.

"Entire families are free to picnic nearby -- while young couples stroll hand - in - hand  its adjacent paths.  

"Not so our rivers in Mexico!

"We need to start taking care of our natural resources, too!

"That way Mexico's rivers will once more run blue and clear, just as they do on the geography maps used by our school children ..."

Way to go, Señor! :)
