Thomas BRAIL

Thomas BRAIL

Founder of the National Tree Surveillance Group, Arborist

He says no to the massacre of trees in urban areas. To protect these masterpieces of nature that are being cut down indiscriminately today, Thomas Brail clings to their branches and camps at their tops. Thanks to him, the cause of trees has gained popularity and received widespread media attention.
Today, Thomas Brail is fighting with the National Tree Surveillance Group to ensure that the law is finally respected and that the massacre stops. In the face of the negligence of elected officials and interest groups, this manifesto is a call to all citizens to join together to save our trees.
