Batman: The Animated Series1992

Ra's Al Ghul:
Look at it, detective. One of the last of the rain forests. The world depends upon it's oxygen, yet the rich see only profit in it's destruction. You, who belong to the over-class have much to answer for.

Batman:
Bruce Wayne donates millions of dollars a year to preserve these forests.

Ra's Al Ghul:
Which are being depleted at the rate of 120,000 acres a day. Does your money solve this problem? No! It will take more than wealth. It will take power, and I fear, ruthlessness. Humankind must be forced to serve the planet instead of its own appetites.

Batman:
And you're the one who'll do the forcing?

Ra's Al Ghul:
I am... qualified, yes. But I may not have sufficient lifetimes left to me.
