"Make no mistake about it -- global warming is a reality. The debate is over," Martin declared. "(Kyoto) will work. It has to work. Kyoto is just the beginning. We need much, much deeper reductions." (emphasis mine.)
Martin is essentially admitting that for him and his environmentalist cohorts simply enacting the Kyoto Accord won't be enough. That's only step one.
They are already clamouring for a Kyoto II, and then it will be a Kyoto III.
And this reflects the problem of environmentalism as a political movement: there is no end game, no point at which the environment will ever really be safe from the threat of industrial society.
