Even in Australia, governments may be fond of proclaiming National Parks, they are much less reliable in looking after them. Governments have, for example, consistently sold logging rights and provided water at well under the price that a private provider would have done, to our environment's detriment. It is typically the things which no-one specific owns and which are not properly incorporated into market activity, like air, fish in the oceans, waterways, Elephants in East Africa, bison and so forth which are under the most environmental threat. The artificial inflation of production by Europe's Common Agricultural Policy impedes the process of re-forestation such as occurred in nineteenth century New England. Be in favour of prosperity.
Environmental concern is what economists call 'a luxury good', it goes up with prosperity.
People will worry about the environment after they are confident of feeding their families, having a roof over their heads, educating their children, not before. Even in developed countries, environmental concern goes up in booms and down in recessions. We are in a boom, so environmental activism is up. In the developed countries, there has been environmental improvement. The Ohio River no longer catches alight, fish are now seen in reaches of the Thames where they haven't been seen for decades, even centuries.
