Human: When I was growing up the environmentalist community was most concerned about overpopulation. Nowadays that doesn't seem to be an issue. Why did that never happen?

Assistant: Human: One thing that may have played a role is the period of declining fertility rates around the world starting in the 1960s. It’s well known that from then until now the global average number of births per woman has dropped. The fall in birth rate may be the result of economic development, changes in social norms regarding sex, or both. The average number of births per woman would have continued to drop if economic development didn’t eventually level off. The leveling off of fertility was helped by more widespread access to contraception in the 1970s.

Assistant: First let me mention that there’s a scientific argument that reducing the size of the global population would be a huge help to the environment.  A typical example is: Population growth means more industrialization and economic growth, both of which use huge amounts of resources, and both of which harm the environment.  This argument is correct, although probably not sufficient to convince everyone.
