3 ways that population growth has a significant effect on climate change.

2 of the ways increase climate change while the third factor can reduce it.

#1 Population growth creates more consumers.

#2 More population can increase land values so people become more driven to work harder to afford a place to live. This can mean working more than one job, promoting more sales and consumption so the bills can be paid and so forth.

#3 Population growth can increase urban density, which might help reduce climate change. In denser developments, folks are less apt to drive cars, for instance due to traffic and difficulty in finding parking. Density can bring better public transit and more walkable, bike able neighborhoods. Density means more people living in shared buildings easier to heat and cool versus as many detached structures. Lots of other advantages of density including sewage disposal versus maintaining so many septic tanks. Density can help the environment, depending on how we plan for it.
