Is overpopulation real? Is Earth filling up with too many humans? How many people can Earth hold, anyway? As our species approaches 8 billion, human overpopulation is a major concern for many people. How can we reduce poverty and our impact on the environment? Do we need a forced one-child policy or something? Maybe not, because when we look at the science and history, populations seem to control themselves. This week we look at all these questions and more.

Thanks a lot to Brilliant for supporting this channel.

Finding alien life on a distant planet would be amazing news – or would it? If we are not the only intelligent life in the universe, this probably means our days are numbered and doom is certain.

Please VOTE! Underwater POLL on Global Warming!

Doris has something to say with this Video:

“Hi guys,

this is an underwater freediving poll about the topic of global warming and climate change. As a scientist I’m pretty informed about the problem. As a freediver and citizen I can see the effects already. So I am curious: What does the YouTube community think about it ??? What do you think ?

To find out, I ask you to DISLIKE the video if you are not concerned about the topic. ( I really can’t belive I’m telling you to DISLIKE my video, lol).
If you on the other hand think that it is a threat for our future, please press the LIKE button.

I will periodically put the actual polling result here:

Acutal polling result ( 1 day after posting):

Global Warming is a threat: 93%
Global Warming is no threat: 7%

So far it looks like there is hope for the planet … 🙂

Thanks for watching and participating ! Have a nice week !


So click on the YouTube logo, watch this Video on YouTube itself and make your choice!
