photo: Upper Solimões River – July 1991
IN HONOR OF THE ARBOR DAY (in Brasil): this tree in the photo, on the left bank of the Solimões River, is a NOTABLE TREE: it is on the nautical charts of the Amazon.
I had the good fortune and privilege of visiting various parts of the Brazilian Amazon Region for over 40 years as a professor and researcher in the environmental area (Environmental Chemistry and Biogeochemistry) at UFSCar (São Carlos SP campus).
I express my deep concern and sadness at the progressive destruction of the forest, lakes, rivers, paranás, and igapós that affects thousands of human beings who depend on them.
I wonder when we will have a solution to these almost countless problems, but I remain (sadly) skeptical of an EFFECTIVE SOLUTION in the short, medium, or long term.
