Is Mars a warning for Earth?

Question

I am not a scientist, in fact I do not even know why this thought crossed my mind unless we have a built in knowledge or understanding that was implanted long ago. Perhaps it is a thought implanted in out minds long ago to warn us of the future when we could understand it.

Look at Mars. Does it answer a question about global warning and depleted ozone and atmosphere? It is a dead planet that once had oceans and an atmpshere. But the CO2 in the atmosphere and the depletion of the oceans through evaporation has created a global desert.

Now with our planet and its ozone holes, it's higher CO2 levels and cold fresh water currents disrupting the salt in the Atlantic ocean could we be headed for the same results?

I know Mars was destroyed by a collision with another large body over 80 million years ago and it was instant how Mars became what it is. The asteroid belt gives us this answer.
But by looking at this result on Mars, could Mars be telling us something

Answer 1

Where did you get the idea that Mars suffered a collision with another large body over 80 million years ago that made it the way it is now? No scientist thinks that, at least not that I know of. I have certainly not read that anywhere, and believe me, I have read a lot about Mars and astronomy in general, and scientists are still debating how Mars lost so much of its water and air.

The reason Mars has no ozone is that it has no oxygen in its atmosphere. On Earth, ozone (O3) is made from regular oxygen (O2) by ultraviolet light from the Sun. Ozone depletion on Earth is due to chlorine compounds, like freon, reaching the upper atmosphere and counteracting the natural ozone making process. Mars has plenty of ultraviolet light and no freon, but it also has no oxygen in its atmosphere.

Answer 2

You need to re-evaluate what you "know".

Mars is the way it is because it has a very small iron core which has cooled completely. As a result, it has no coherent magnetic field to protect it from cosmic or solar radiation.

As a result, the solar radiation has "burned off" most of the atmosphere. If there was plant life on Mars at one time, it most certainly died off due to the solar radiation, the cold, and the very thin atmosphere.

In short, Mars is the way it is because it is the way it is. It's not a "morality play" for Earthers.

Answer 3

maybe it is just a p[lace} to look at it and study like a picture of the earth

Answer 4

maybe, like a portrait or a photograph that is very old.
