Whilst we tend to think of humans as harmful to the natural world, we can very well be the foster it. For instance, the 'Terra Preta' or dark earths, which today are extremely biodiverse areas found in the Amazon forest, are the result of man's effort to make the land more fertile.

This sculpture represents the layering of organic matter and top soil that naturally occurs overtime in woodlands. It is a symbol of fertility and biodiversity.

This sculpture was made at Boisbuchet during a workshop conducted by TAKK architecture.
