From the article:

“This growth is premised on three conditions: [...] 3) improvement in the transportation infrastructure in Brazil that will lower the cost of getting agricultural crops to the port.”


Good luck with that. If you can actually pull off some trick to have our internal transportation work, then you'll be regarded as either a god or the biggest lobby spender in the history of the world.

the higher the CO2, the faster the rate at which plants converts CO2 into oxygen.
If brazil soils are so bad why is brazil a major agriculture exporter in the world market.
is basically calling for hurricanes -> I don't refute this. Neither do I confirm. Can you explain? Or is it part of climate change and result of temperatures. Either way, how do you know what magnitude it's gonna have. It's hard to predict magnitude

higher co2, higher temperature, better conditions in cold countries such as canada scandinavia russia

And the higher the rate we all die of respiratory problems. Air's already fucked up enough in most of the country for that.

Amazon soil is infertile. Which, by the way, is the one you suggest we use. The fertile soil we got is all being used now, save from a couple indigenous tribes we somehow didn't get rid of yet.

There's a huge ass water depository under the amazon, and the amazon itself is one. It's not in a particularly wet place aside from the river. The common rains happen due to the plants sweating what they absorb very quickly due to heat. Kill the plants, and the water depository underneath it will be freed, and the plants' sweat will produce massive atmospheric water increases. This translates to hurricanes, tornados, typhoons, floods, mass rain and much more. Can't know the magnitude, but we do know it's pretty darn big.

Alright, Team Magma. But this means the ice on these countries will melt, causing the loss of lowlands including but not limited to a large chunk of Poland (and a lot of Russia/Norway), not to mention that countries/regions that are already hot will become hotter and unbearable, making a very large chunk of Australia, South America, Africa, the USA, the Middle East, central Asia and China completely desertic and unusable, meaning loss of land in general.

Speaking of Russia, the permafrost is gonna go to shit with this plan, causing massive methane emissions to the atmosphere. A single molecule of Methane generates as much heat as about 25 molecules of carbon dioxide. If it starts large-scale melting, it definetely will heat up the world, causing more and more to melt, heating up more and more, in a large scale chain reaction.

Ultimately, temperature increases are expected to be around the 10ºC which makes most of the world impossible to live in as the atmospherical temperature would be far above the body temperature - then comes heat strokes, skin cancer and dehydratation for pretty much every single species. If we survive that, animals/plants won't, and we won't have what to eat. At the end, your plan failed.

"If you can actually"

Very optimistic, but it won't happen any soon. The current government and probably the next few don't care about the rural population (we literally had a slave owner as a congressman). For this kind of large-scale production, we need trains and waterways, trucks won't do it, and our government is balls deep on lobbyist money from car companies, so you can guess where this is going.

I think the impact will be much lower and you're overestimating it. At this point we can talk whatever we want, but now some data to back up our statements would be cool. Otherwise it's a word vs word bouncing back and forth.

I think the impact will be insignificant. And if don't agree, let's leave 15% of amazon intact, perhaps this would convince you

Wow Berdan, you should do some research. Zeph told you the entire story and as far as I see everything is correct.

world is way too hot already, I really hate global warming.

Anyhow, there's enough food to feed all the world's population and then some, hardship is in the spread of food.

We won't know what the consequences are for sure until rainforests are cut. Also farmland can always be turned back into rainforest, so everything can be reversed at any time.

"A simulation was performed in which all rainforest in Africa were removed." - this is unreal simulation. The rainforest will not turn into a desert. Some plants will always grow there. For example fruit trees could be planted on huge areas

Most of what I said can be googled and found in less than 2 minutes for confirmation, but I guess the killer point here is lack of soil fertility. Ignore all the damage and problems this would cause, it still wouldn't work because the amazon soil is terribly poor in nutrients.

http://wwf.panda.org/what_we_do/where_we_work/amazon/about_the_amazon/ecosystems_amazon/rainforests/

"Tropical soils are notoriously thin and poor in nutrients. In some parts of the Amazon River Basin, white, sandy soils are found, which have evolved through erosion over hundreds of millions of years. And yet, although these soils have lost their mineral content and fertility, rich rainforests grow on them."

I think the impact will be insignificant. And if don't agree, let's leave 15% of amazon intact, perhaps this would convince you


It's not far from becoming 15% even without your 'plan'. The first pic is the original forest, the third one is just about how it is nowadays.



It's also worth noting this isn't the first forest we fuck around with - nowadays most of the state of São Paulo i ridden with air pollution and large chunks of smog as well as bigger temperature variation, despite in the past being one of the biggest concetrations of rainforest:



For the record, it isn't just rainforests we do that to. Meet what's left of the Cerrado, a savannah-like region in central Brazil where soil is a lot more fertile and where most of the soy agricultural expansion is happening in (the second pic is from 2002 - not even up to date, probably considerably smaller after the soy boom and chinese partnerships):



We won't know what the consequences are for sure until rainforests are cut.


So we just try and hope for the best? Won't work.

Also farmland can always be turned back into rainforest, so everything can be reversed at any time.


No, it can't. A rainforest takes many many years to grow back, since larger trees have longer lives than crops. Also, crops lower the already acid soil of the amazon's fertility.




Anyhow, there's enough food to feed all the world's population and then some, hardship is in the spread of food.


Juq's got it nailed. Save from Africa and East Asia, population growth is too limited to ever threaten the agricultural growth of the world and our ever-increasing capacity to generate food. The issue is always spread.

Extra:

It's not in a particularly wet place aside from the river. The common rains happen due to the plants sweating what they absorb very quickly due to heat.


It's also worth noting that even if floods and general problems due to too much water don't happen, problems with too little water WILL happen. Locking the depository due to the lack of deep roots as well as tossing the water into the atmosphere is going to lower the water levels in a good chunk of the country, causing - at the very least - a mass scale energy crisis, since we essentially run on hydroelectric powerplants: http://www.eia.gov/todayinenergy/detail.php?id=16731



This has happened in the recent past, mostly in the southern regions (graph's in portuguese, but blue means major energy crisis while greenish gray means mild energy crisis):



The cause, as mentioned? Low water levels on reservoirs.



You probably don't care about this last bit (at least I personally don't, so I wouldn't expect you to either), but in the case you do, this also means a large scale genocide of river-based indigenous tribes, which are visibly focused on the amazon:

Global warming is going to cause a temperature rise in Scandinavia and Russia?
If you do not know anything about either global warming nor the way rainforests work I wouldnt start this discussion.

Min34 at least I got many new perspectives. Now I know that perhaps still viable, or perhaps not, my idea is not as perfect as I thought at first.

Are you kidding us? Admit your defeat already.
Zeph showed that your idea is litterally TERRIBLE.

Thats why you brought it in first place. But never start a discussion when you have a Brazilian around.


Well done Zeph, by the way!
