The population is declining across the world. As countries modernize family size decreases. This is due to many factors; women's access to healthcare and education are the biggest, but also economic factors forcing women to work. This is most pronounced in countries like China and Japan.

Some folks worry about population collapse, but this is not realistic. What is more realistic is as countries population decline they will be less able to grow economically, and capitalism may fail. We will probably not have the economic resources or work force to implement large scale climate change solutions in the future. Carbon capture needs a growing economy to be economically feasible.

The people promoting climate change doom simply have not seen the demographics. We will peak some time around 2050 to 2100, and population will decline precipitously after that.
