The problem here is akin to that with relocation as a solution to wage
costs. It works as long as there are previously unutilized areas in which
to dump waste. But eventually there are no more streams to pollute, or
trees to cut down – or, at least, there are no more without serious immediate
consequences for the health of the biosphere. This is the situation in
which we find ourselves today after 500 years of such practices, which is
why today we have an ecology movement that has been growing rapidly
throughout the world.
