vue - How we can make crops survive without water | Jill Farrant
As the world's population grows and the effects of climate change come into sharper relief, we'll have to feed more people using less arable land. Molecular biologist Jill Farrant studies a rare phenomenon that may help: "resurrection plants" — super-resilient plants that seemingly come back from the dead. Could they hold promise for growing food in our coming hotter, drier world?

a great talk, very hopeful, thank you
-
surely you lose more then 1% of ya 65% of water when u work out.. or am i wrong..
-
tot aan de top van de atmosfeer bedoel ik maar als dus steeds minder vocht steeds hoger is en dus lucht bovenin helemaal zonder vocht is dat het zo zit en des te meer alleen maar lucht in plaats van vocht dat zo steeds hoger gebouwd kan worden en dat het totaan de dampkringrand kan komen het is van een fantast in feite snap je of het zo zit heeft die alleen maar een vermoeden van maar bewijs of feiten die het bekrachtigen heeft die niet alleen maar het vermoeden zo zeg ik fantast wand hij gaat van vermoedens uit die waar of onwaar kunnen zijn
-
luchtvochtigheid hoe hoger het is des te minder vocht en dan uiteindelijk totaal geen vocht meer en zo eigenlijk iets bouwen dat zo hoog reikt dat het de atomosfeer bereikt maar dit is als het niet zou kunnen fantasie van een onwetende fantast ja van een fantast is het dan
-
ik neem aan dat zo dus ook een hetelucht balon werkt het vocht stoomd weg de lucht blijft over en dan gaat de balon stijgen of het daardoor komt probeer en je komt erachter maar daar ben ik niet kundig in maar andere mensen juist wel
-
meer lucht in een balon en zonder vocht in de balon ik neem aan dat het dan minder gewicht heeft en dus mogelijk kan gaan stijgen
-
Ballonnen die mogelijk heel wienig vocht bevatten kunnen mogelijk omdat ze lichter zijn dan lucht en lucht meer uitzet omdaqt er minder druk op staat steeds hoger stijgen dus weinig vocht stijgt het met veel lucht zonder vocht het is mijn theorie dat ballonen dan stijgen gaan als alleen maar lucht erin zit zonder vocht

So clever, well done Jill

........ Yo, Dude and Dodette,
If you feed them, they will reproduce naturally and double the population once again. Let Mother Nature take care of them naturally. -
Awesome lecture, thanks TED & Ms. Jill Fallant, indeed we need more lectures like this...

Can I translate and write rabic subtitles directly using YouTube?

How about data and not just 'global warming PROJECTIONS'..;
With so many lies it is hard for those of us who are concerned to know what to believe. -
Just wonderful with "how do you define genetically modefied". There are enough issues to discuss but not even knowing that it is not about the mere process of genetical modification but the extent of it is helping nobody.
-
copy+pastes prepared message from imageboard saying it's so great that this woman talked about a science thing and not one of those annoying social justice things
"Yes yes, I am not wasting my life for sure" -
This isn't going to really help the true problem though; the real problem will be rainfall and fruiting. If a plant survives a small drought, that's all fine and good....but if it is stunted in growth, it may not grow much fruit in the end, or worse, may not grow any harvestable fruit by the time the growing season is over.
On top of that, if a plant is fruiting while the drought occurs, the fruit will probably die or won't grow as well, or could even do other weird things like becoming more pulpy or thicker skinned. In the end, these will not only make for bad tasting fruit, it could also lack in nutrition.
So a better solution it seems, is to make sure there is more water, even if it must be pumped from the ocean. We as a species, need to solve the water problem, and create massive desalination plants automated and run on solar energy. Costly at first, cheap in the long run.
We have to realize that the plants we grow today, are designed around growing larger quantities with more flavor; they're generally much more brittle than their ancestors. Sure we add some tolerances for things like diseases, sometimes sacrifice flavor for yield.....but what kind of future is it where we sacrifice flavor? I'd say the better solution is to prevent from having soo many mouths to feed in the first place, rather than to be brought down by over population....otherwise we'll all end up eating tasteless blocks of food substance while billions of people choke the world. -
It all makes sense now. The out of control population growth is in poorer geographies. So when the Green Movement talks about population control and clean energy they are talking about the same thing. Removing cheap energy from these poor places makes mass death a certainty.

another Lobbyist from the GM Rockefeller foundation !!! Scumbag !!

dont worry old lady , worlds population will be greatly reduced by the US army till 2050 , dont worry

This is great, it's not heavy genetic mod so hopefully the fearful ignorant masses will be at ease. The plant clap was cute too.
