Rather than plantation can we change carbon dioxide to oxygen artificially ?

Question

For global usage

Answer 1

sure, plus u ll get rich in the process :

4x CO2 = 1diamond + 4x O2

With all those diamonds u can buy an EV and save everyones lungs and the planet at the same time

Answer 2

Traditionally, the seas have done this.

Water warms up, sunlight becomes stronger, CO2 is high so plant life blooms. I expect it will do far more than any human effort.

Answer 3

That would require vast amounts of energy which we do not have.

Answer 4

carbon dioxide isnt the problem in the world, the problem is methane, its 10 times stronger than carbon dioxide. we should find a way to get rid of that, not the CO2.but it would be good if we could do it artificially Dont think you can though without using other substances on a mass scale

Answer 5

A small company in Queensland called Linc Energy has a share in another small company who maitain that they can change carbon dioxide into bio fuel and oxygen from the emitions from coal burning power stations .The company is established to take gas from the unmined coal seams and turn it into green liquid fuel and make diesel and jetfuel without sulfur in it which means green fuel

Answer 6

It can be done chemically with small volumes of air, and this has been used in submarines and rebreathers.  However, it's impossible to do this on a global scale.  Nothing artificial can take the place of  plants in the ecosystem.  We need to protect our environment before it's too late.

[edit]

Obviously the terminally ignorant don't like science.  I'm surprised the person who gave me the thumbs down didn't give a thumbs up to the "alchemist" jokester below.  That's what some of you want -- magic.

The arrogance of some people just astounds me.  They seem to believe that we can recklessly destroy the whole ecosystem and still survive because "we can do anything with technology".  If we started running out of oxygen, we might be able to produce enough artificially to keep a few people alive in a hermetically sealed bunker, but the rest would die, and the survivors would eventually run out of food.  Contrary to what you may have seen in science fiction movies like Aliens, we don't have the technology to "terraform" an entire planet by artificially producing oxygen.  If we start running out, we'll be out of luck.
