Which gas in are planet is the most dangerous to the amtosphere and why?

Answer 1

Hydrogen sulfide and chlorine gas cause the most damage per unit volume. Destroying the Ozone layer and causing acid rain.

Carbon Dioxide shouldn't even make the list... While it may be primarily responsible for greenhouse warming effects, trapping solar energy inside our atmosphere, it takes Tremendous amounts of CO2 to have any effect at all. Also, CO2 is absorbed by plant life which then provides us with Oxygen. The problem we have now is that burning fossil fuels is adding carbon from plant and animal life from eons ago into today's environment. Today's plant life cannot keep up as the situation is out of equilibrium.

Either a new equilibrium will be reached or there will be an algae growth explosion in our oceans where they can thrive on the the CO2 rich atmosphere we are creating (not there yet).

Answer 2

There are* two ways of looking at dangerous gases in our* atmosphere. Gases that are directly harmful to human health and gases that are harmful to the long term habitability of our planet.

Example: Ozone. It's poisonous to humans when directly inhaled but it shields us from ultraviolet and other shortwave radiation.

Carbon Dioxide is mentioned a lot as a potentially harmful gas, but a natural amount of carbon dioxide is mandatory for plant growth and excess CO2 in the past has been removed by our oceans.

So our atmosphere requires balance more than anything else, a lot of gases we might consider dangerous are only dangerous becuase of dramatic swings in their concentration.

Answer 3

You mean earth's atmosphere. Except oxygen, nitrogen and other inert gases, all other gases are potentially dangerous. Carbon dioxide because it increases the greenhouse effect. Nitric and nitrous oxides and sulphur dioxide because they cause acid rains. Hydrogen sulfide and chlorine are highly toxic.

Answer 4

In "are" planet? geez, take an english class! but Greenhouse gasses such as Co2 and chloroflourocarbons are immensely dangerous.

Answer 5

carbon - its everywhere, builds up, and is causing global warming through the green house effect
