I feel, and I think just about every body can agree with me, that over population is a major problem the world now faces.
The discussion is on the severity of the problems and the solutions.
IMO, over population is be far the most pressing matter the world faces, yet strangely heard about the least. Less over population would mean less pollution, less global warming, less economic problems, less war, less diseases, less starvation, and the list goes on. The one problem I can forsee is if the population lowered, it might cause some economic problems because of a lack of consumers for businesses, mainly in real estate.
I think the best course of action at this time would be to expose this problem to the public. You see people on tv talk about depleted oil, global warming and all kinds of problems, but never over population. So have more magazines articles, more newspaper articles and more talk shows talking about over population so that the public becomes aware of this problem. Also, have above sources ask people to please consider over population when planning on having children and suggest adoption if people want more than say three kids.
If the situation becomes more dire, perhaps have mandatory vissectamies to people who have more than 3 kids. I understand this is a violation of freedom, but the healthiness of our world should, to a certain extent, take presidence over personal freedom.
