Admiring the time and effort you put into your video and detailed information you offer.

Houston: We have a problem...

[StefanAxelWels]

Im interesting what happen with this salt in Aral sea. In this pic it obvious some toke it and this you use for wether control..Maby thats seceet but the heck.

[StefanAxelWels]

Its not table salt...

I feel sorry for you

[MeX2004]

Consider the following facts:

a) Rain forests influence the rain fall

b) Most of the rain fall falls on the ocean itself

c) Plants need the high frequency spectrum of the light for photo synthesis not the lower heat side of spectrum.

What if in far distant future when we are able to carry large payloads into space and are able to patch sun light such a way to create localized weathers to channel rain falls to those areas which don't get enough rain fall.

I know it sound crazy in our time

[MeX2004]

But what if we can manufacture suitable material which can block infrared sunlight and are able to patch sunlight over certain areas that would create local situation like artificial rain forest effects or artificial high altitude effects to manipulate local weather.

I know these are the kinds of things we will need to learn from terraforming Venus. Can we change local weathers by changing the temperature of the large region and by manipulating high/low pressure system?

I consider the fact youre a bloody imbecile

[MeX2004]

You don't get it do you? Its not down the hill from here on for you, its off the cliff for you morons from here on. :))

I would have appreciated a better time-laps of the rain forest. 1975 vs 2009 is pretty steep.

your absolutely correct sometimes they are looking in the wrong places....I love when they nail it ....beautiful!!

[TheCharleycat]

sometimes academics can be really dumb.

lol

[tunderman66]

Hey, I agree with what you say, I am an uni student. But I think sometimes we are dumb because we are looking at the wrong place, in this case, you maybe able to find the answer by talking to a farmer or an elderly living in the forest.

[TheCharleycat]

this is bollocks. science for a hungry world? stop building food mountains and letting food rot and goto waste

[chrismeachin]

TheCharleyCat - Thanks for your polite and intelligent contribution.

Did you even watch the film? And what have NASA got to do with food mountains?

Monitoring land use change is invaluable precisely so that we can use land, and therefore food, more efficiently.

The really fantastic part about comments like yours is that most people can ignore them as being sub-moronic and unworthy of engagement.

You are the weakest link, goodbye!

[TheCharleycat]

chrismeachin - thank you for your sarcastic reply. your comment was quite amusing, in fact i even managed a little giggle. thank you for thinking my sub-moronic comment was worthy of engagement. it seems you and nasa hasnt caught onto the fact that there has been so much food produced from the lands we are already cultivating that they are piled up high like mountains and left to rot.

[Keylimedelight]

dont feed the trolls

[rennnsymbol]

+1 Too true!

[ganggreensoldier]

lol

your a sharp one

sharp like jello

[TheCharleycat]

dude have you ever tried laughing at yourself. its kinda fun. i do it all the time.
