you don't have to reduce your carbon footprint

From the monthly natgeo I read, I found out there is an interesting way of reducing the CO2, main cause of global warming, and consequently creating whole wrath of the mother earth by toppling the meterological effects. Klaus Lackner, a physicist thinks if the we are able to plant trees to cover the whole earth, it would not be enough for the greens to convert all the CO2 to O2 gas, due to the limiting factor of a tree, which only can do that during day via photosynthesis process as we know it, but at night they releases CO2 just like a human does during breathing mechanism. Plus, production of CO2 is more rapid than one can ever imagine, therefore it is not really practical to plant trees, while waiting for it to grow which only can make 50% contribution. That's why Lackner a bit cynical with the whole green thing ( well it helps a lil bit).

Lackner and his colleague, Allen Wright did a simple experiment using a plastic (resin) to impregnate with sodium bicarbonate, it pulls CO2 out of the air. Extra C converts sodium carbonate back into sodium bicarbonate. Simple enough? Here comes the tricky part, in order to to that, they must be building lots of scrubbers(resin material with all the conversion) around the places, like the windmills-to generate electricity. scrubbers-to pull CO2 gas into the scrubbers and channelling it down to the earth which CO2(liquified) greatly benefits -
  1. flush oil out from the old reservoirs
  2. stored in the saline aquifiers where high pressure due to the depth will keep CO2 in liquid form as it is in a vast amount
  3. Injecting liquified CO2 into volcanic basalt under the sea will secure it as an inert carbonate mineral-tested in Iceland
  4. Adding hydrogen into the CO2 to make hydrocarbon which is less insurmountable to our environment

In my opinion, i strongly agree to it because since we can't change our lifestyles in vast, why not create something that can improve our environment drastically rather than to reduce and control it, why not cure it? Problem is where should we build this because countries that contribute the most carbon footprint had already use up their land, the effectiveness? the amount of environmental damage? safety and technical features?

I was intrigued by Lackner and Wright because they could create such simple chemical reaction in trying to solve the world's most crucial and talk about problem and though it sounds iffy and unrealistic but i believe in this idea. hopefully it will work
