Firstly, all political advertising should be banned.
Advertising is just lies anyway, we all know that and we pretty much expect our politicians to lie to us because they advertise.
Candidates for state or federal legislatures would have to campaign in their local areas on local issues and win their votes in the old fashioned way.
Demolish the two-party system. It is failing in every western democracy that I know of as the major parties move closer to each other pollitically and it seems that not even a change in government brings a change in policy any more.
Discourage your governments from participating in conflicts unless there is a clear and identifiable risk to your security. Democratizing the world at the point of a gun is a self-defeating exercise. People who hate you for shooting at them are not receptive to pretty words about freedom and liberty.
Start getting right with the Planet. Do it at a grass roots level, do it at home, in the community and in your state.
I don't know how but I can guarantee that if we humans continue to degrade nature, nature will decide we are a disease or a parasite and act to heal itself of us.
Demand a better type of education for our children, an education that teaches them the tools for a lifetime of learning and gives them an understanding of the importance of their actions or inactions (responsibility). Focus on balance and allow the child to pursue those paths of learning that they enjoy at the speed that they wish. (we all learn at different rates)
End the consumer society. Refuse to participate in a wasteful, destructive system that delivers nothing more than mountains of garbage and waste. Reduce, re-use, recycle.


That's a start. I'm sure there is much more that could be done.
