aquadoc, I'm sorry you don't see the staggering contradiction in some of the things you say. On the one hand you ask
why does it push buttons that there is a segment of folks trying to help make things better for everyone? It doesn't push any buttons because most people are aware and most people will try to do something if they feel it is reasonable and will really makes a difference. But most important, that the contributions are being made fairly by all.
It makes no sense to turn off your TV early and sit in the dark while all others around you are up late partying. It makes no sense for the USA to impose "carbon credits" while China and other countries spew out waste and filth like there is no tomorrow.
The first problem is that it isn't so much awareness as it is /caring/ for a lot of people because they know that what little they can do /won't/ make any real difference in the bigger picture. There have been people who have written books and made movies about climate change, then go around flying in big jets and owning huge homes all around the word with massive energy consumption. What the average individual can do pales in contrast to the hypocrisy of many of the uber-rich and big governments.
You say that in the USA, overpopulation is not the problem but in 3rd world countries it is. Overpopulation is always at the heart of it no matter where because there is always a direct correlation between resource consumption and resource assets! For the most part, resources are rather fixed, and resource access is determined largely by infrastructure.
Infrastructure is driven by economy. It costs money to build it and most of that money comes from taxes through productivity. You make it sound like someone is withholding resources--- you talk about vulgar overuse and waste of resources. Give me an example? You sound like it is a matter of the "haves" and the "have nots!" Western countries use more resources because they both have them available as well as create the economic base for themselves in order to provide and enjoy it!
You talk about Chad, Ethiopia and Sudan--- what do any of these regions produce? What products do they generate to create wealth and a tax base? I can't remember the last time I bought anything made there. Is it tourism? Where do they generate the tax base to create the infrastructure?
Then it is a matter of having the resources in the first place. Resources in these regions are extremely limited. There is no economy to finance the infrastructure to provide it. Governments cannot just pull it out of their ass and create it as their finances mostly come from the people, so bottom line, it still comes back to overpopulation.
The USA has a lot more economic power to support its infrastructure but it is stretched to the breaking point because half the people in the country pay little or no taxes. Sudan and Chad have no economic power to support very little infrastructure, so again, it is a matter of there being more people in the region than the resource infrastructure can provided for. Overpopulation.
What constitutes overpopulation varies with the regional resource infrastructure. Please do not try to make this a problem of western civilization--- women are being dragged off into the woods in Sudan because of poverty and crime. Lack of wealth invites corruption and suffering. Population growth in all regions of the world have outstripped the resources to keep up with it. Poor nations in Africa are particularly vulnerable because they have little economy in the first place to deal with it.
Solution: somehow give all these poor regions the economic machinery to generate wealth, taxes and a better way of life? Wrong again, because now, people would just start having even more kids! It always comes back to population, because without people, there is no resource consumption. Earth Day is a great idea, but it only mainly creates awareness in those least in need of needing it. Everything we do today depends on energy and electricity. You can't ask people to go back to the 1800's. The problem is the number of people drawing from the available resources.
Until people stop fighting between themselves, between parties, between nations and identify common goals, not much will change. Efforts are being made to meet demand but these processes work slowly. There are social programs to help the poor, but these programs do not help them get out of poverty, but to merely /exist/ poor! When you finance something, you get more of it, so in helping the poor live poor rather than get out of poverty, you just get more poor people needing more programs! That is the problem. Anytime you have more people taking from the system than contributing, you have a problem.
The one thing that people can do that will make the biggest difference is population control, get populations back in line with regional assets supported by viable economic productivity. It is going to get worse before it ever gets better because in order to meet that, ideally, we need to cut population in most regions by a third, in some places maybe half, either that, or get a lot of these people to be a lot more /productive./
