Greener War. Fighting the ecological bad conscience

Thanks for your extensive answer!
regarding steel vs lead: steel does have a little higher thermal conductivity, so the bullet could be a little hotter - people who were shot do remember a hot impact, if they remember the temp at all.
However the termal conductivity of brass is significantly higher (about 4 times than lead) - I bet left-handed shooters know what I mean
The question is also if a steel bullet needs more powder to propel it, so this could also lead to more powder residue and a hotter barrell.

And you suddenly discover your ecological conscience over 1200 tons of lead?

Sorry, but I must ask for a check of priorities.

I am not against it in principle. I just think we should have more urgent things on our minds.

You're spot on with your first paragraph.

However I find the question of the ecological impact of war a very interesting one, not only since yesterday. Being interested in WW2 and growing up in a time where an oil spill was common news, I asked myself the question about the impact of the sunken tankers quite early. (The answer is the ships back then were significantly smaller than modern oil tankers, often carried lighter oil than and were mostly way more offshore)
Then there were the reports about the impact of Agent Orange in the Vietnam war, a heritage from which people from both sides suffer till today.
I think the 91 Gulf War brought the devastating ecological effects of war back into our collective minds - the Exxon Valdez was a joke compared to the burning fields in Kuwait and the largest oil spill in history in the Persian Gulf. Not to mention topics like Urane depleted ammo or the Gulf War smptome.

So yes, measurements to reduce the ecological consequences are good - though I must admit that on the first read the biodegradable landmines the article mentions sound just as insane as something like organic poison gas. People who live in areas with extensive mine problems would certainly jump for joy if those things would just resolve in the earth.
