In Brazil, Trees To Call For Help If Illegally Felled
Damien1972 writes "The Brazilian government has begun fixing trees in the Amazon rainforest with a wireless device, known as Invisible Tracck, which will allow trees to contact authorities once they are felled and moved. Here's how it works: Brazilian authorities fix the Invisible Tracck onto a tree. An illegal logger cuts down the tree and puts it onto a truck for removal, unaware that they are carrying a tracking device. Once Invisible Tracck comes within 20 miles (32 kilometers) of a cellular network it will 'wake up' and alert authorities."
Anything that raises the hassle level to untracably do illegal/harmful activity will probably either catch or deter a reasonable chunk of the would-be criminals. We live with knowing that the locks we use in our homes could be picked, and if someone *really* wanted to take the time and the risk or spend the money, they could probably get in in various ways, just like we never achieve 100% safety from other crimes. That doesn't mean our safety measures are worthless though.
For every problem, there is at least one solution that is simple, neat, and wrong.
