[edit] Save The Human Race

In a Discover article a while ago, it was noted that this may be the way to save the human race, due to that fact that the population of this world is rapidly increasing. If we could convert swaths of the rainforest to agriculture, while taking care of the environment, using organic farming, this may be the way to feed the world. Because it uses charcoal, which stays inert for thousands of years, it could be used for carbon sequestration, which combats global warming.Winkelix 22:02, 13 June 2007 (UTC)

You're so right on. 74.195.25.78 (talk) 03:55, 24 January 2008 (UTC)
Another way to feed the world is to quit the endless food race and begin NOW to lower our insane numbers.

From the article, the description of terra preta sounds a lot like the indigenous were just plowing in their garbage--back in a society that had no refined products to throw away. Charcoal being the spent wood from the previous nights fire. —Preceding unsigned comment added by Rich Lather (talk • contribs) 01:21, 7 April 2008 (UTC)


Actually, there is evidence that the soil was intentionally created. For instance, the charcoal was finely pulverized before being aded to the soil. However, this article is of poor quality (I would almost argue that it should be rated as start-quality,) and does not do justice to the topic at all, so it is understandable that you might have that misconception. The article doesn't even discuss the role of symbiotic bacteria in releasing nutrients from the charcoal, or the role of charcoal in retaining nutrients from rainwater. It also does a poor job of explaining charcoal's role in nutrient retention, or its abiility to reduce need for fertilizers and pesticides. Works of Sweat (talk) 16:19, 1 May 2008 (UTC)

For those who study it there is no doubt about its being intentional. Please refer to Dr Lehmann's site for example and from there via his outside links to many other hubs of tp study. There's also a very good tp discussion on 'Bioenergy lists' where you can ask all the questions you care for on the tp topic. Here: Terra Preta bioenergy list. Good day.

[edit] "inappropriate tone"

I wish the person who cared to put that on, also cared about explaining what s/he meant. Hello, are you out there? Please don't just make critics, also make suggestions. Thanks. Basicdesign (talk) 06:27, 3 June 2008 (UTC)
