We already are dramatically curbing our population growth. The rate of global population growth has plunged since ~1970. The rate will drop from a peak of about 2% per year in 1970 to 0.2% by ~2060. We've already roughly cut the growth rate in half in 40 some years. By the late 2030s, we should have the rate of growth returned to pre industrialization boom numbers (when the rate began to rapidly increase). It takes time to bring the numbers down, we'll be near population contraction by the time we're into the 2050s.
