How do humans negatively affect biodiversity? Our actions in a given environment cause problems directly and indirectly. For more biodiversity tutorials, visit bit.ly/cas-khan.
This video (posted in 2014): "the # of threatened species qin an average nation will increase 7% by 2020" Me: wait...but we are already IN 2020.......oh sh--
Very well said. Seeing and experiencing all the changes on our climate nowadays. Stronger typhoons, unpredictable weather and the length of light and darkness. Those are only examples of the changes that we're currently experiencing due to our irresponsibility. People used of having the machines do all the work. Wherever you go, everyone is already using technologies in their everyday living which greatly affected our lives, especially those on the near future. More technologies, the more and even worst calamities they'll be having. So for those who're not yet aware of the disadvantages that we'll be having, I do suggest you all watch this blog for it can help us very much!
Great video...it goes straight to the heart of the question...Despite me studing Economics and not being into biology or chemistry at all, I managed to understand everything that was told in the video. However, I would suggest to you to give some more data....it's tough to realise the real size of the problem without crunching any numbers, I think...
awesome video. Hello there, I am Azam from Malaysia, Can I use your video for teaching, educational and research gallery presentation? The purpose of the gallery is to educate young people to love their earth/nature. Thank you.
good video but i wish they are some colors in the video. i want to ask why did jellyfish can survive or abundant on the oxygen depleted zone? can someone explain to me?
Population growth is NOT exponential and hasn't been for years! AND, population growth is NOT the problem. The problem is rampant consumerism: the unstoppable appetite of wealthy nations for energy and "stuff". One person in North America consumes as much as 50 to 100 people in countries like Bangladesh.
What if we just maximized agriculture? I don't think most countries in the world maximize their land for agriculture. I would suggest that we plant more supply locally. Instead of getting exports, which is better for the short term but not for the long run. Can't we do that?
I guess Thanos wasn't that bad with his train of thoughts then.. Yeah I said it, cus we truly are killing the planet with no regards to what the future would be
I wish he could talk about population control, but that topic is scary to most people, especially religions that encourage many, many children per couple.
@@crimsynheartticker3732 have you seen the talk by 'Jeremy Jackson: How we wrecked the ocean'? it's not over yet... by the way are you studying convervation biology?
This is not science or scientific [necessarily]. This is general theories, some of which have scientific basis in fact. He speaks of the fact that population growth and human reproduction is exponential. But so is human death, disease, accidents, homicide, and other factors. He says that by 2050 the world's population will be 9 Billion people. But 9 Billion people could easily fit in the United States and still utilize less than 15% of the total land area. Roughly 1% of the world's land is inhabited by humans presently. The so-called Malthusian Limit is also a theory, -a theory with no (or little) basis in scientific fact. It's interesting that Malthus, the order he arose from (precepts/ ideology of nobility and aristocrats), and his writings, came just after the American Revolution. That may be just a coincidence, or it may not be. There is no doubt that biodiversity is important, that species do go extinct, or are threatened. There is no doubt that we are using more land, more resources, and that pollution, and environmental degradation are definite problems (among others). But he also fails to take into account, that just as humans adapted to invent technologies for greater food production, plants and animals can also adapt to these changes; And have throughout history. That doesn't mean they are never affected by human activities, but simply that they are dynamic and constantly evolving along with humans. He gave many examples of how species, ecologies, and environments, are impacted by human activity. I think one of the most visible ones is the mystery of so-called colony collapse disorder in Honeybees. I don't believe they know the exact cause of it, but a predominate theory which I subscribe to, is that the continual bombardment of high frequency wireless microwave electromagnetic radiation in the atmosphere affects all living things negatively. Yet you will never hear the financial elite and their Agenda 21/ICLEI cohorts complain about that. Because their goal is to utilize such technologies to control and surveil us all as they force us into highly urbanized compacted zones. As for the destruction of forests, there is a renewable, sustainable answer which is the answer to most of our problems: Hemp. Massive industrial scale hemp farming/agriculture. I simply want people to understand that buzzwords like sustainability, biodiversity, and others have dual usages. And that these terms will be used both legitimately and illegitimately to promulgate the concept that we must give up our private property, liberty, freedom, and rights, to save the planet in the name of sustainability, sustainable living, biodiversity, and other feel-good buzzwords, while allowing Communist central planing and New World Order Totalitarian Collectivist Government to dictate the way we live.
Humans may only occupy 1% of the total land area, but 57% is inhabitable and Americans specifically use more than 10 times the sustainable amount of resources. Hopefully the New World Order Totalitarian Collectivist Government sends you to live in Antarctica since there is an abundance of resources that they don't want you using.
Hello friend, education is means of realization and understanding not means of pointing out( information correct or not or how much correct it is). only the things which should be adapted is take some steps like plantation, veg-meals, population control on personal level. Other things will be done automatically. You don't have to worry about it. You have sharp brain use it in straight resulting path rather than in diverting path(which took you at origin after went through whole video). I hope you will understand.
If you're watching this video, and you care about the planet and the animals and plants that live here... DON'T HAVE KIDS! JUST DON'T DO IT! EVER!!!!!!!!!!!!!! Especially if you live in the US or Europe! People who grow up and live in those places use a disproportionate amount of resources compared to children from Indonesia or Gabon. If there were fewer people, each person would have a greater quality of life! Even if you're an intolerable asshole and you hate biodiversity, the destruction of it /will/ eventually destroy you, because you'll starve and have untreated sewage in your drinking water. And this could all happen not too long after 2050.
while population drops do improve quality of life for others, people want to reproduce because it is etched into the nucleus of every cell in our body.
Now Im disappointed of having an open eyes., 👀👀 it is better to stay ignorant than to understand things like this. the problem they've made make us suffer, and it will become much more worst in the next coming generation., now I understand why ellon musk wants to leave earth.
