"If we do not voluntarily bring population growth under control in the next one or two decades, the nature will do it for us in the most brutal way, whether we like it or not"

This quote by Henry W. Kendall is a warning about the repercussions of unchecked population growth. He is suggesting that if we do not take action to reduce population growth in the near future, nature will take matters into its own hands and do it for us in a severe and unforgiving way. This might take the type of scarcity, illness, or other natural catastrophes that might significantly reduce the population. Kendall is highlighting the significance of taking action now to avoid such a catastrophe from occurring. He is likewise recommending that if we do not act, we will have no control over the outcome and will be helpless to stop it. This quote acts as a tip that we need to take obligation for our actions and be proactive in attending to population growth.
