A logger cuts down a forest and sells the truckload of lumber for £1000. It's cost him £200 for the hire of the machinery and the diesel. He hasn't planted any more trees to replace those cut down because it would affect his profits of £800. He is selfish, inconsiderate with no regard for the habitat, animals or the preservation of our woodlands. Topic for discussion, what do you think of this way of making a living? is it ethical, could the government do more? Should the logger be served with an ASBO? How did the birds and squirrels feel as the logger cut down their homes? (There are no wrong answers).
