Venice is built on trees. Millions of them, upright, making pylons buried in the lagoon and surrounding swamps to support the buildings. But there are still plenty left - some 500 years old. (Here's a photograph of some huge trees in Venice - an entire avenue of them: http://www.worldofstock.com/closeups/TEI1510.php - type in trees, venice, or this ref: Image ID: TEI1510 ) A town without trees is a sad place indeed. Hot, airless, noisy, depressing. It is obvious that JRussell has a phobic fear of trees - and needs help. At the present rate of out of control population growth, people will destroy the planet - then how will all the billions of starving people exist? Trees will return, as they did in South and Central America.
