The food thing is a valid concern. I too come from a long line of farmers. My great uncle recently retired after a lifetime of farming, and my great grandfather before him started that farm. We had farmers and ranchers on the other side as well.
Anyhow, about soil mineral depletion. Pertaining to alternative fuels, I've been told that the kind of corn cheapest to use for alternative fuels/biodeisel uses more water and takes more minerals from the soil. Not for sure how they plan to amend the soil, but my uncle used to plant something like winter wheat, let it go to seed and then till it under and leavve the field dormant. That replentished a lot of the minerals, but was kind of costly. (He grew corn....had to use pesticides....) It is a problem.
And thanks for the idea on a good read. Here in the next month or so, work becomes a bit slow and I'll have plenty of time to read.
A tad bit off topic, but in keeping with the same theme, another big concern is the growing food shortage. I don't completely understand farming even though I come from a long line of farmers..just not my immediate family, but with the growing demand, farmland is not being treated properly, and of course is also a finite resource. With it not being allowed to lie fallow for the appropriate amount of time, combined with many of the chemical fertilizers and things being used, it is becoming stripped.
Not sure if you saw my posts in one of the other threads about this topic, but the documentary I saw basically had scientists a few hundred years from now studying our civiliation and trying to figure out why we collapsed (it was done by the author of the book Collapse). It was fascinating. Basically the major issues were pollution...water ways especially, and farmland. How we essentially destroyed ourselves even with all the technology we have. The book Collapse is one I highly recommend...the author has studied all the great civilizations and their downfall...from the Roman Empire to the Mayans, etc. It's a bit dry, but address' much of this stuff. It's not a book touting Global Warming, no worries..lol. It takes a more realistic approach..that which we can control. Really interesting and makes you think. He does talk alot about our current dependence on oil as well, both from being dependent on other countries, cost and the fact that it is a finite resource. You might enjoy it.
Our little community has a pretty good recycling program going. There are multiple recycling bins at various convenient locations, and it is making a difference. Our local schools are implementing a program as well. More of a conscious effort, kind of "think before you use" attitude. So really, we are saving tons and tons of recycling from going to the landfill annually. More can be done.
And about oil. It is a finite resource, no question. We do need to develop viable alternative energy sources. I listened to something on Public Radio here in the states concerning alternative sources. I really only remember a few points of the discussion.
1. Wind energy: a lot of the components concerned with the wind mills are petroleum based. In order to positively impact oil comsumption in regards to building these components....we need new materials.
2. Getting gathered energy to the grid: they mentioned that all of the energy gathered in wind farms doesnt make it into the grid. Technology is such that a considerable amount of energy is lost. Not that its costing anything, but its very inefficient. In order for more energy to make it to the grid with todays technology, we need more wind farms. Now you are dealing with the "N.I.M.B.Y.'s" Not in my back yard.
The obvious benefit of this technology is, wind is renewable. Oil magnate T. Boone Pickens is sinking money into it.... theres all kinds of speculation as to why. My personal opinion, not that it means a squat..... the technology is very affordable now and he wants to corner the market on it. Bless him, he's got the money to do it.
Nuclear energy??? Seems as if more people are warming up to it, but again...nobody wants a reactor in their back yard and disposal or storage of the waste is a big issue.
Youre right, there are no easy answers. We do have some of the worlds brightest minds attacking this issue. As with anything, cost is an issue. Everything needs to be cost effective and it has to generate enough funding to become a self sustaining entity.
I've actually heard something similar about Hybrids. They seem like a good idea, and I certainly haven't done much research into them, but my understanding is they don't really help resolve the issue.
I know we need the other major industrial countries on board and wish I knew the answer. I just don't think that not governing ourselves accordingly is appropriate. The other big issue is oil. It is finite and will eventually run out. We need to find good alternatives. The documentary I watched a little while back said that although there are alternatives, the use of them will change our lives in the sense that they are not as convenient nor will they provide what oil does. So unless people begin to be willing to change their own individual lives it won't do much good.
I am not a "tree hugger" by any stretch of the imagination. I am however a realist. It sounds like the jury is out on whether or not we are contributing to global warming (I have never believed that there wasn't some natural cycles at work), but either way we are destroying our planet a little bit at a time. We are starting to see mandatory recycling here in Canada, although not everywhere yet. My city does not yet have it. Where my parents live garbage has to be put out in clear bags, and you are only allowed X amount of bags per household per week. If they pick up folks notice recyclables such as cans, etc. they don't pick up that bag. If you have more then your X amount of bags, then you have to attach a tag you paid for. It is helping. They also provide you with a recycling box and pick that up weekly as well, so you are not on your own. It's good...at least it's a start.
I don't think there are any easy answers here, but I do think we have to get serious. We need good alternatives and need to encourage other countries to do the same...not sure exactly how, but I do think it should be somewhat of a priority.
I agree that we need to do more about recycling. It should be mandatory, it would create a few new jobs. As much science there is saying this is a real threat, there is as much science saying it is a recurring, natural event.
The deal with this is, if we are going to make any positive impact on the environment by recycling and cutting emmissions and so forth, all countrys must jump on board. For all the good that North America could do, China and or India's lack of effort would make it a wash.
This thought just came to mind, so thought I'd insert it into the discussion. Hybrid vehicles.... Ive heard it said that mining the materials for the batteries in hybrid vehicles leaves a bigger carbon footprint that operating a Hummer for the vehicles life time. I do not know the validity of that statement, but think I will try to find something on it and get bck to you.
I can't comment on the Cap and Tax issue as in all honesty, I don't know much of anything about it.
I still maintain however that regardless of Global warming or climate change or whatever the case may be, there are two facts not in dispute....pollution is a big problem for a variety of reasons, and the planet climate is changing. Whether or not the two are related seems somewhat irrelevant to me.
We do need to start changing our ways...more put into green energy (oil will not exist forever), recycling (yes, I know there are still problems, but we need to be working on it), and taking care of our enviroment in general.
As for the climate change aspect...if doing these things has a positive effect, great! But I don't feel that the lack of absolute proof that that is the case should change the fact that we need to change as a society.
I would love to see other countries step up and work on their problems as well. However, I don't feel that their lack of willingness to do so should excuse our behaviours. We can lead the way in the west by example. Perhaps they will choose to follow suit.
This is another of those issues that impacts the entire world, not just a single country. I wish it would not be made into a political issue...it's too important.
I'm personally glad they've brought this back to the forefront. This will remind people that dems are desperate to get cap and tax through. The public doesn't want it and we can't afford it. IF this is a man made problem, nothing will change until China and India do something about their emissions.
Jesus, really? Uhm, did anyone consult with Al Gore...for hell's sake?
