Nature when preserved has a way of sustaining itself. Human intervention could at times disrupt this self sustaing process. As an overseas Guyanese i have been to Lethem sever times, the scenes are breath­taking. This is not only a heritage to be preserver for us Guyanese people, but for the entire world, and for generations to come. The beauty of nature cannot be replicated, and tells me that there is a master­mind who designed it all. Thanks for the great work you are doing in the Rupununi Dr. Watkins, I will look for your book on Richard.
