Electric Cars...Are we really ready?

Although I think electric cars are the future I have some major concerns.

1. What happens to dead batteries??? Right now we don't manage this well. What are we going to do with these monster car battery packs? What about the spent lithium? Is there any environmental issues?
2. How much supply of lithium is there? Can it support the current/future demand? To go all electric will require a lot of lithium.
3. We are experiencing electric brown-outs now due to high usage. What happens when we all want to charge our cars? Surely the current infrastructure can't handle the load. A more distributed design MUST be in place to support electric cars.
4. What about the fine metal dust from the generators? The friction wears the pads which creates dust that floats in the air or cakes to machinery.
5. Does the electric noise or battery discharge affect animals/humans?
6. Is there any affect having all that electricity surrounding us? 

You would think with all these concerns I would be saying slow down... but I am NOT! Athough there are issues with electric it is still far superior to the fossil fuel choices. I want to make sure we don't just switch to a different pile of crap. We need to do this for our descendants and it has to come quickly to ensure we actually have descendants.

Park cleanups 2010 update

Well I have been cleaning both Avening and Glencairn parks this year and there is quite a difference between the two. Glencairn requires much more of my time for cleaning. Each week this year the Glencairn park has built up a garbage bag full of crap plus at least one large item(like tires/metal). Avening on the other hand requires picking up 10-20 small peices of garbage each week with no large items. Although Glencairn is a busier park the problem seems to stem from only a very few people. There is at least one person that smokes at least 5-10 cigarrettes per day in the park. At least I pick up that many butts of a specific brand almost daily(plus other butts). Another lets their dogs(multiple large dogs) crap all over the park. Fortunately this year there hasn't been any major dumping going on and there has been a few people actually picking garbage up. Glencairn does not seem to be having any major parties this year(usually there are 5+ already) so the garbage has been dramatically reduced this year.
No matter how I look at it the parks are cleaner and easier to maintain this year than previous. The amount of garbage I see is noticably less than previous years. Especially butts and beer bottle caps. However since the outhouse has been removed from Glencairn some people have used the park as a bathroom and left toilet paper in several places(not nice).
Oh well, there will always be something that could be improved.
