population pyramids in certain areas

Yesterday in Human Geo, Mr. Schick showed pictures of different population maps on the board. I found it very interesting because we looked at what the world's population will look like in the future. It scares me a bit because I feel like by the time my age group is 60, the world will be over populated and I think it will be a huge problem in the future. I am not sure what the governments will do about this over population. We also were shown the population pyramid of Japan and it was shocking to see that Japan is actually decreasing in population. I wonder what Japan will do in the future for this decrease in population. I enjoy looking at these population pyramids because it helps me understand what is predicted for the future. I also find the pyramids very easy to understand and I like looking at the different types for certain countries and counties because they all have different shapes.
