To handle global problems we need global institutions. We need a world government to deal with these big problems. In Canada we have three levels of government. Each level has its exclusive areas of responsibility. We need a fourth level, that would not meddle in these lower levels, that handles global problems such as ecology, waste management, inter-country conflicts, aviation rules and disease control.
People are so afraid of such a new level.
This mirrors the suspicion the original thirteen American colonies had before considering federalism. Now the benefits are obvious and the drawbacks don't see all that dreadful, but at the time, it was nip and tuck if the federation would fly. We have tried anarchy. It simply does not work. Let us at least try adding one extra layer of government.
