En als gevolg daarvan komt er een veelvoud van de bacteriën rondom je wc, top idee..

heel handig filmpje, ga deze gebruiken voor mijn o&o presentatie

Een paar decennia terug groeide ons schip in een paar jaar flink aan met een dikke laag mosselen welke bij een hellingbeurt verwijderd moesten worden , nu op dezelfde ligplaats, zelfde onerwaterschipbehandeling geen mossel meer te vinden, ook niet meer aan de kanten en meerpalen. Zou dit komen door de op mosselzaad verzot zijnde rode rivierkreeften? De veelvraten in het Delflands watergebied?

Grappige video. Is dit ook verantwoord als er vissen in de vijver zwemmen? En zoals in andere comments wordt gevraagd: zorgt het roest niet voor gevaar voor planten en dieren?

en hoe zit het dan met roest?

It's in India ancient time we know as mitti rooh or mitti ki khushboo we worship mother earth.

Okay

Een grote baars eet ze met gemak op, daar weten veel baarsvissers alles van. Ook snoek en snoekbaars eten ze graag. Helaas zijn die vissen er niet genoeg door de beroepsvisserij in de binnenwateren, maar ook muskusrattenvallen zitten veelal vol waardevolle snoek, baars en snoekbaars die het niet overleven, ik heb het zo vaak gezien... zonde. Eigenlijk zou je juist die beroepsvissers moeten uitkopen en de vangst met bijvangst van muskusratten moeten stoppen, dan kunnen roofvissen floreren en die eten de muskusratten en de rivierkreeften. Daarnaast kun je dan nog gericht op rivierkreeft en muskusratten kunnen vissen zonder ongewenste bijvangst.

That’s so cool! Thanks for this video

Awesome research, this could help a lot in a world of anthropogen nutrient overload !

Joh laat die beesten toch. Zo schadelijk zijn ze nou ook weer niet. De meeste schade word nog altijd veroorzaakt door de mens.

Kreeft komt ook voor in de lage linie in Doesburg

Wat een kkr filmpje

Prachtige video! Het is echt leerrijk!bekijk zkr eens mijn videos! Ik heb mij net geabonneerd!

jazeker

Excellent, thank you.

Lijkt niet echt op een ei van een scholekster. Geen tekening. Lijkt kippenei.

Het is weer BBQ🔥 seizoen. VIS is duur, dus een paar gratis kreeften van straat plukken is wel lekker toch,buurt feestje. Biertje erbij. In Zoetermeer lopen ze gewoon over straat in voorjaar. Best gevaarlijk wanneer er een paar zijn overreden, glad wegdek.

Dankuwel voor de uitleg. Maar ik kon het niet lezen want ik ben blind.

Anyone else here because of school?

Does herding of ruminants, such as by predators causing it, create the conditions where ruminants cause soils to build?

It was a catastrophe it was not humans slaughtering Animals how could it?

kan ik ze vangen in rijmond ?

Ik wil ze graag gaan vangen om te verwerken in een heerlijk gerecht. Maar mag dat wel?

Fantastische tip ! Na een paar dagen waren de zweefalgen helemaal verdwenen en was mijn vijver weer helemaal helder. De draadalgen bieden wat meer weerstand maar gaan er ook aan :-)

een watermandje vol spijkers zou dus ook helpen

ayy lmao

technology is the answer

fucking humans .. pathetic species .. somebody nuke humans for fuck's sake .. be a man and do it

Blah blah on the climate change talk. Population keep growing in numbers day by day, and Nature loses its fight each day that passes. We over fish the oceans and then the 1/4 to 1/3 who have a toilet hooked up to a sewer system, we dump are crap in to rivers or the ocean along with tons of garbage. We are the only animal on the planet who defecates in water that 2/3's of the people on earth, can't even imagine the idea of it. And on ground , we drill it, blast it, mine it and pump it. then clear cut it, hunt it and farm it or kill it. Only thing everyone can agree on ! The human population can't and won't ever do anything at all towards pollution. And it does not matter what your beliefs are .Even if you are a eco nutcase who recycles anything , and pedals to work. Or you don't believe a word of climate skeptics as they are too far out in the fringe to even listen to, while you are driving a jacked up turbo diesel 4X4 truck. Governments only talk shit and do even less, and really only agree to a climate agreement only to look like they care. Also to make the people who cry climate change, feel good. The little done is never going to be enough, and to do enough is going to mean KILLING off humans numbers. Ok I don't like the Idea of myself becoming a "sacrificial lamb" for the world. So I am choosing life in a human created shit hole. So go ahead every body do what you have to do and either live your life day by day. Or just stop your crying and worrying about everyone and give up your own number in the population of humans. All talk and no action except the idea of Carbon Tax, AND IT is the biggest fucking joke on the working class people. Or are you really that stupid or naive to think that a new "TAX" because it is named "Carbon Tax" for the environment will help the environment? How is this new tax going to be spent any wiser then over the tax dollars now spent foolishly now? Its all so retarded now a days, IDC anymore because im tired of the shit fed to me on a environmental agenda shaped spoon . Or watch Dodge piss on my leg and say yes the new 700+ hp challenger is good on fuel milage. world of the gullible and sheep i tell you

clathrategun has fired... humans dont get it yet.. and what it means ..

I would LOVE to say that we definitely know the magnitude of the effect. But we all know how dangerous it can be when people make unfounded claims. We show that this is definitely going to happen and have a considerable impact. For an analogy, we couldn't predict exactly how much damage would be done to a person who walked out in front of a bus moving at 50mph. But we know that there would be a significant amount of damage, and that information should be enough to stop people from walking out in front of busses

Great (and frightening) video. But I'm afraid mild words like 'could' and phrases like 'this suggests that ...' just won't get the message across. Scientists have been issuing warnings for 30+ years and as a result we have some agreements (will Mr Trump keep to them), some solar power and a few wind farms. The only slight chance we have is if the western world changes it's philosophy of life from 'economic growth and rampant consumption is good' to a policy of 'we're sorry, we'll share what we have, accept less and try to live in harmony with nature and all the peoples of this earth'. Are there any wise and strong enough leaders out there who will say what we all need to hear?

Really good video, nicely balances depth of detail with simplicity and approach-ability.

Agriculture is the gold for the future Africa. Youth needs to be engagedede

I really enjoyed watching your presentation and agree with what you are saying in this video. You are very correct that there is not one quick fix or magical solution, I have learned this from my own experiences from farming on my project is the Spanish desert, I have made lots of mistakes but life is about experiencing "the learning curve" so for me I am enjoying the failures and the small successes. I can see that you are passionate about your work and I wish you all the best in the future. Thanks for sharing.. Roy ;-)

Sorry lady but we were not here 2 million years ago. We've all been created 6,019 years ago. So stop spreading your brainwashing lies please.

How can I connect with Dr Liu? I'd like to affect the marketing of 'feeding the poor' and change it to 'growing gardens'. Please connect with me.

Liked it but . . . look at the audience at the end . . . now the oppressor comes back offering transformational change?? From the comfort of what looks to be a pretty nice conference room.

@allon33 What's your point here? Nothing has to be wrong with being goal and money focused, even how evil it may sound into your ears. Terracing a deforested mountainous area has a huge impact on improving water infiltration to the soil and prevents further erosion as well. By this means ground water tables are replenished and in this way nature is facilitated to restore itself by providing suitable conditions for forest regrowth.

We have opened Pandora's box but now we need to close it and return the planet back to the garden of Eden.

Terraces ffs, is that all?

For Permculture you will need to plant trees, 20% trees for each paddock of crops, and then wait 20 years for it to work. Oh what a surprise, these fools have ADD and can't wait 20 years, or we can't pay them for 20 years. U r all Losers, for you are money and goal focused dumb dumbs.

People who are trained in Mono-culture will lack the understanding of Permaculture.

Inspiring work we are all engaged in!

The research work in Ecology, ( the science that studies the relationship between man and nature) here made by Tania Vasconcelos, working in holland. The research in the sciences (investment), made by any country,is a step forward in the evolution of the economy of that country.

Wat een kletspraat

golden toilet! Great work, Tania

Leuke voorstelling van dokter ecologie, ga je ook te rade bij de "wijze uil" op je bureau ?
