Sending carbon to their roots to become soil carbon could sequester it for centuries

Lawrence Berkeley National Laboratory and Oak Ridge National Laboratory researchers claim that global warming can be fought through the use of genetically altered trees and plants.

The leaders of the study – Christer Jansson, Stan D. Wullschleger, Udaya C. Kalluri, and Gerald A. Tuskan – believe that creating forests of genetically altered trees and plants will remove "several billion tons of carbon" annually from the atmosphere, ultimately helping in the battle against global warming.

Researchers plan to increase the efficiency of these trees and plants' natural processes that allow them to remove carbon dioxide from the air by transforming it into "long-lived" forms of carbon. They would like to do this first in vegetation, and eventually in soil. 

Genetically altering trees and plants' absorption of light isn't all these researchers are looking to do, though. In addition, they'd like to make it so that these plants send more carbon into their roots as well, which would transform some of it into soil carbon. This could stifle the carbon and keep it from the air for centuries. 

Researchers are also genetically altering plants to "better withstand" the complications of growing on marginal land in order to produce improved food crops and bioenergy. This could increase the amount of carbon plants take in from the air significantly. 

The combination of genetically altered trees and plants sending carbon to its roots to be put to rest for centuries along with improved bioenergy and food crop production could yield results that are beneficial to fighting global warming and its consequences. 

This study was published in Bioscience.

5) Start-up google-earth and take a look at how much free-land there is still. It's not that bad. As people get richer they make less babies. The world population will stabilize by itself, i am not worried.

If we were using more resources annually than the earth can give us, then we should have run out last year and had none this year.

Not quite. For example, if can't grow enough trees annually, people will cut down trees in the forest.

If we extract fish at a rate greater than they can reproduce annually, fish population will drop.

See it as the earth already having some ressources in the bank account, when we take more than the interests or our deposits can cover, we deplete it.

Here is the link I got my information from ( it`s in french ):

It says that, based on US National Science Academy numbers published in 2002, we were already outspending the earth`s capacity by 20% in terms of its regenerating capacity for forests, lands used for crops and renewable energies.

Yep, it's actually scary how fast reproductive rates have started going down. China doesn't actually need the one child policy in most cases except for the tradition where they need a male child to support them when they get older.

If you want more detail, read this, it's very interesting:
