I doubt that getting economists to see the impact of their policy for, say 10,000 years, will be easy or effective given the blip of geological time that all of humanity has been on the timeline. Although the environment is affected by humanity more now than it has ever been, this time is still a blip. I am of the belief that when humans become too burdensome, the Earth's reaction will be to reduce the population in the unfeeling manner of nature. If we're talking environmental justice, which seems to be where this discussion is going, we're talking human timeline again. While the empathy and love of human beings may reduce the amount of suffering in the world, it will not eliminate it, and that's life.
Pollution causes someone, animal or human, to suffer.
It is also my belief that we may,as a group, get to the point where we can agree on principals or a policy statement. However, the solutions to environmental problems must come locally, community by community, based on their values and what they are willing to live with in an informed capacity. Think globally, act locally. This may open a whole other can of worms, but I think it's important to address. Local communities should be addressing those issues.
