Ecology on Khan Academy: Why are polar bears found only in the Arctic? Why does mildew grow in your shower and not (hopefully) in your sock drawer? Learn how ecologists study the interactions between organisms and their environment, and how these interactions affect where, and in what numbers, different types of organisms are found.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom.

    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.

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

    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)

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

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

    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

    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.
