Are you joking, or are you really this obtuse? Bill Gates, for example, is one of many people concerned about this, and has talked at great length about uncontrolled population growth being bad for everything, not just the environment. It has nothing to do with racism - it has everything to do with you not paying attention to this particular field, and the discussions, studies, and findings which have come from it. That your mind instantly leaps to "racism" and guessing the motives of environmentalists is rather telling of how you see the world, and your place in it. Ouch.
Quick hint: The more developed a country, the lower the birthrate. To stop the population from exploding, the world should help less-developed countries develop. Access to education, healthcare, and security means population growth slows down massively.
Disney wouldn't be where it was today if the notion of public domain didn't exist - almost their entire early output was based on public domain texts. Using Disney as an argument for stronger copyright is fraught with issues as now they are a dominant player when it comes to stricter copyright, but wouldn't be in that position if lax attitudes towards copyright had not existed in the past.
The main people who would benefit from restricted copyright would be you and me, because unless an artist has the blessing of Disney or over $4bn, they will not stand a chance in hell of being able to publish works based on that universe, and we will never get to enjoy their art. Just imagine how much awesome work has already been missed because some judge told them they can't make it? Why do you prefer the bean-counters to the brush-wielders?
