I really learned many interesting things about population topic. I only knew that there is a big problem with the population in China and it is controled ,and in developing countries but not at this point. I was very impressed about the women' situation in Sub-Sahara Africa.It is really important that they get educated so they can help themselves first, and then the entire nation.
Another thing that I was surprised to learn about it , is about Japan, I didn't even think that they have a very low birth rate. Solutions are needed to help saulving the problem in both sides , that's for sure.

Skyscrapers
The term "skyscraper" was used in 1880; after the first tall buildings were build in the
Before there were towers made of heavy stone. Towers had thick walls and the rooms were dark and overcrowded. Windows weren’t very common, it could disadvantage the structure.
With the discovery of the steel begin the new era of modern skyscrapers. The
New structural designs made skyscrapers even lighter and stronger.
As skyscrapers get taller and taller, engineers were faced with a new problem: the wind. Today's tallest skyscrapers, which are almost 1,500 feet tall, must be 50 times stronger against wind than the typical 200-foot buildings of the 1940s.

Skyscrapers represent the big issue for the population explosion in our days. In my opinion skyscrapers is a good think because it permits to locate a big number of people in one place into the profit of green spaces that can be saved.

The situation in different areas are so different. Some countries has expanded population. On the contrary, some countries has problem in low birth rate. People should find solutions for both side!
me too, I just know that Japan population are declining.
We really learned a lot in this population unit. We're expanding our knowledge...haha...good...
Hi Alina, I was surprised to see Japan's problem is dealed with much accuracy and objectiveness. That is the current situation in our country. For me too, women in Africa gave a strong impression.
