As someone said earlier, we outsourced much of our polluting activities (manufacturing) to the developing world and as someone else said, shipping the finished products back here compounds the problem due the polluting nature of the shipping industry. Now we are looking at opening up our market to Australian livestock which will make matters even worse. Much of the world seems to be doing the opposite of what is needed for a sustainable long term future. There needs to be a wholesale change in mindset rather than just thinking about local CO2 emissions which will only scratch the surface of the problem.
