Your article “Pre-Columbian raised beds may save vanishing Amazon,” by the A.M. Costa Rica wire services is to be greatly applauded. I hope you will pass this article on to the Spanish language news services of Costa Rica and across the world.
As a retired soil scientist, I can appreciate the good scientific truths in this article. We have long known that slash and burn agriculture was/is a non-sustainable agricultural method, but I did not know the pre-Columbian inhabitants of the Americas had long ago discovered this.
I hope persons in all parts of the world will be energized to learn more about what was long forgotten. Now that this information has been rediscovered maybe we can use our modern technology to better understand how to live a bit more sustainably. People with indigenous ancestry in the Americas should be filled with pride.
Thank you for providing this important information to your readers. I look forward to learning more about this in the future.
