Toxic gas from oceans+excess gas from human activity=Mass Extinction?

Question

Since the Oceans are heating up at a rapid rate causing alot of coral to die killing a lot of fish that feed off of them to die and all that dead decaying matter falls to the bottom off the Oceans decomoposes producing more toxic gases and the warm water can no longer hold the toxic gas because of the temperature is higher then add that to all the toxic gases from human activity and the fact there are not enough trees to use up all these toxic gases does that mean we are due another mass extinction? How long would it really take to kill most species off including our own?

Answer 1

I have worked in gas about 50 years and in the west Texas oil field where they have the toxic gas H2S which will kill very quickly . The first things is not all the gases that u worry about but the oxygen level. Normal level is 20.9% of our air is O. If other gases increase that will go down ,so u watch the O. If it starts down it doesn't need to drop much below the low alarm point of 19.5% if it does u will become unconscious and fall. The cloister to the ground is where the heavy gas goes and it will kill u there.

The CO2 which u are worried about is all natural and the plants with photosynthesis recycle the CO2 .
