Obviously nothing is going to be fixed overnight. We have thousands of years of patriarchy and misogyny to overcome and we are still not free of their influence. Getting rid of the madonna/whore divide and its modern equivalent of victim/lying industry shill would help.
There has, after all, been a lot of progress in the area of women's rights over the last 100 years, at least within Europe. There's still a long way to go, but at least we are not officially and legally the property of men any more. We can earn our own money, vote, drive and (at present) have access to contraception and abortion. Even though the odds on conviction are still lousy we can call the police when we are sexually assaulted and, legally, be treated as the victim of a crime rather than collateral damage in a crime committed against our male owner.
As to what we can do, now, about the problems surrounding porn? We can seek out and/or encourage others to seek out the stuff that is ethically produced. We can give our own kids sound, sensible education about sexual behaviour along with the standard stuff about the mechanics, contraception and disease - teach them that sex, first and foremost, is supposed to be pleasurable and that means that everyone involved in a sexual encounter should be enjoying it and enthusiastically participating - if someone isn't enjoying it then it needs to stop immediately. We can remind them that not everyone is particularly interested in sex in the first place, and that your level of interest in sex is not, in itself, some confirmation of your moral righteousness.
And we can get our heads round the idea that, just as sex is predominantly a recreational activity that everyone is entitled to engage in or avoid, porn is a type of entertainment in which performers should be treated fairly and not coerced into working, decieved, bullied or exploited.
