What would happen if oxygen levels on earth increased and co2 levels decreased?

CO2 and oxygen proportions have changed, up and down, over long geological time spans. When it happens slowly there is a change in the types of plants and animals as evolution weeds out the species that do not do well in the new conditions.

Because plants and species depend on each other for producing these gases the tendency to change the proportions is slow. ANd survivable- things adjust slowly.

But a sudden change could be a real killer. As oxygen goes up oxidation rates go up. THings burn faster, rust faster and age faster. Humans, for one well known example, can not take too much more oxygen, children needing oxygen at birth sometimes have their eyes burnt and destroyed permanently at birth by excess oxygen. Plants would struggle with a CO2 shortage as they are poisoned by high oxygen. These weakened, vulnerable or dead plants would become nearly explosive in a high oxygen environment, lightning or other causes would cause fires far beyond anything we have ever seen- which would in turn help to bring the proportions back to what they are now.

Earth Oxygen Levels

by way of fact that there is amazingly little loose hydrogen accessible, the hydrogen used from engines would come from a technique call electrolosis. Water is divided into hydrogen and oxygen, then the hydrogen is used for gas. So, you will have no internet earnings of water interior the ambience as a results of using hydrogen generated by using splitting water. If something, there'll be an exceedingly small decrease in entire water (no longer something you should extremely stumble on), by way of fact the hydrogen saved for gas applications would not exist as water molecules. even nonetheless, I agree that hydrogen won't be an exceedingly good answer. The electricity has back from someplace, which skill burning fossil fuels, using nuclear ability, etc. different skill of turning out to be hydrogen for gas additionally require engergy imputs. you should apply renewable capability components to split the water, yet you lose capability interior the conversion. it may be extra useful just to apply, say, methane immediately quite than use it to the two generate the electricity to split the water or placed it by way of a technique that would unencumber the hydrogen from the carbon atom. base line is that hydrogen as a gas is largely no diverse than using a battery. the only reward I see are a million) you do no longer usually generate the pollutants ultimate interior the city the place there are a number of individuals to breath it and a couple of) fossil fuels would be extra effeciently burned in a ability plant than in an inner combustion engine that the owner would or won't correct look after.

If their is large amount of oxygen (means very large) then if you even burn a matchstick then thier can be an explosion....

Their will be a lot of problems to trees and plants........

And about animals and humans their will be fun........

But not much, as coming to negative--

nitrogen has a greater importance....

The ration of gases 20 years before were the best......

All will die in next 1 or 2 years if this happens......

So, if this happens... ENJOY

then CO2 will increase anyway, since we take up oxygen and release carbon dioxide from our body when we breathe.

there will be an unbalanced eco-system. but that will never happen. :P

We might catch fire and the plants might die.

WE WILL LIVE LONGER
