    viewing this in the time of corona pandemic, I think we have approached Malthusian limit. 100 years a cycle. maybe, who knows!

    Its either family planning of tragedy. I prefer family planning, In Bangladesh population has begun to decline thru family planning. I think that there is a freak out when some people see this happening, but we need to reduce human population drastically to an ecologically sustanable level. No, need to freak out. The only way to reduce our population is thru family planning education. Just the simple explaination of the situation can go a very long way. War and any kind of forced reductuon causes the population to grow at some jucture. Social instability causes ecological instability.

    I think we'll stave off the Malthusian limit until we run out of space. Yes, travel to new planets could be done, but there are only so many planets that can support life as we know it.(Man, that took forever to spell right)

    Malthusian limit maybe is already here. Countries once developed, faced birth rate decrease and keep staying low. Japan, Korea, China.

    Hmmm. Regulation and density dependence are tautological. Density Independent factors are limiting factors, not regulating. The ecological definitions are clear.

    Animal crowding researches have been published for 70 yrs. and are available online. Population density stress is Mother Nature's long evolved population regulation mechanism, about which this lovely fellow has no knowledge. Stress R Us

    For the human overpopulation problem another point is that developed countries go through a demographic tranistion

    Maybe it was said for humour, but I'm surprised the narrator perpetuates the misconception that lemmings commit suicide by running off a cliff. It was staged by the filmmakers in Disney's White Wilderness.

    10:01 Well, we have another planet so if we overpopulate Earth, we could probably go to Mars if we have the technology to do so then.

      Why use huge resources on that, instead of solving the problems on Earth ?!?
