Another take on this Hi all, Interesting reading to say the least. Here's my thought which kind of ties in with enjoying our hobby (and our lives for that matter). IMHO, we're spending way too much money on studies, computer modelling, and having arguments/discussions about whether or not global warming is an issue, why don't we just use some logical sense as to what is a sustainable way to live? And sometimes go inside ourselves to find out how we feel about something rather than relying always on others to tell us what is right and wrong? There is so much to enjoy in our lifetimes, such as model railroading (told you this would tie in with MR ). I walk to and from work everyday, partially because gas prices are higher and I prefer to save my money for other things, but also because I enjoy the exercise. I see things I wouldn't see if I drove to work everyday, such as the cherry and plum trees blossoming right now. But I realize not everyone can walk to work so if you have to drive that's fine with me too. When I do drive it is in one of my collector cars and yes, they are not as fuel efficient as a modern car but I do restrict my driving and I feel better about it. I also try to buy local produce when I can, partially because this has less impact on the environment but also because I like to support local growers and our island and province's economy. And usually it tastes better as it was harvested when it was riper. I also have collected various household discards to scratchbuild items for my layout. Beats having to go to the hobby store everytime I need something. And it's amazing what can be used and the surprised reaction of people viewing my layout when they learn what I made something out of. I can usually find another reason other than environmental to be more conscientious about how I live my life. Let's lighten up a bit (we're way too serious about everything), enjoy life as best as we can and not worry so much about everything. After all we have a great hobby to enjoy!
