I was sad when I heard that we were giving up on this earth and trying to terraform mars. The melting of the polar ice caps has begun and there is nothing we can do about it. We can stop putting greenhouse gasses into the atmosphere but that wont do anything about the gasses that are already there. The sea level is going to keep rising over the course of the following years and the temperature is going to continue to climb which is going to cause mass extinction. On an unrelated note, Yellowstone is showing signs of nearing an eruption which will shoot debris into the atmosphere, blocking the sun and possibly throwing us into another ice age. So take your pick on how you think the world will end and hopefully we will have colonized mars by then.
We truly stand no chance of at least maintaining what is currently still present of this earth. While I see everyone talking about the ice caps melting, The ozone depleting and Yellowstone erupting a major issue I've yet since addressed is the mass amounts of people whom are not educated enough to help us on the path of salvation. Countries like Indonesia and India are rotting corpses of their former glory, The insane amount of ground and water pollution as well as the overwhelming number of people means continuous destruction to their ecosystem. The lack of contraceptives and education available to the majority of the populations add to the flame and just continually bring in more unneeded citizens as the urbanised areas spread throughout land. This issue is also wide spread across countries along the entire African continent and several parts of South America and South East Asia. This is all achieved through poor economies not being able to fund schooling and mass urbanised areas pushing deeper into untouched land to house, Feed and sell consumer based products to the growing population. Which itself is achieved through a lack of education as the newer generations will exploit their own land for corporations, Their government or illegally, Not fully aware of the consequences. If some of this seems repetitive than good, The world is stuck in a system which just keeps growing everyday with each new human added. While I mostly focused on 3rd world countries, 1st world countries will bring us down just as easily as our consumer based lifestyles fuel pollution and promote money hungry businessmen to begin exploiting resource reach areas such as India, Africa and Indonesia to satisfy our wants. Yet another system were due to the lack of education in some of these countries, Locals are willing to engage in environmental destructive jobs if it ensures money, Which will be paid due to the wealth of the employer which is due to the mass consumer market. The world is facing it's next and possibly last mass extinction event, Our ecosystems are dying, Our animals are following suit and we're literally opening holes in an invisible sheet that protects us from the suns rays. We've surely done a number on the planet and without literally every country putting aside their petty differences to actually attempt to make change we're doomed, Maybe not in our lifetime but the human race and at the least the face of the earth share the same fate of destruction.
Our environment's health, such as it is, is in the decline. Since the year 1990, we have been past the point of no return, and rather than finding a solution to the problem since then to lessen the burden of climate change on future generations, we have elected to continue to pollute our atmosphere. We behave as though we have an infinite amount of resources available when, in reality, our resources are finite. We behave as if our environment can repair itself, when in reality it won't. Twenty years ago, our environment may have been able to recover on its own, assuming we quit polluting it with fossil fuel emissions completely, but today, we are bolted to this roller coaster climate change nightmare, with our brake lines cut.
To say it is "to far gone" is simply mistaken, and you state that "... I heard that we were giving up on this earth and trying to terraform mars." yet I see no citation for this evidence. While I do agree that it is to late to save the vast majority of the ice caps, it is not impossible to stop or at least slow down the melting to an acceptible level. Regarding your cries of mass extinction, yes, the seas will rise as will the temperature. I am not a specialist on weather patterns, but I feel that if the heat rises so does the rate of evaporation, which in turn creates clouds and rain which would help the temperature level off, at least by a little. I agree Yellowstone will eventually erupt, however I do believe that if the situation becomes dire enough, people would find a way to release the pressure gradually to at least reduce the wide-spread effects of the eruption. As for the ice age, that would be one of the least of humanities worries about a super-volcano eruption. Other greater concerns would be the massive amounts of toxic gas released into the atmosphere. Furthermore, regarding your hopes of colonization of mars, that would be impossible at the current time, due to the massive intra-country conficts going on. Also as a final thought, you speak as if the earth would die, it is a rock in space, it will be fine. It is us who would die.
Our environment has been damaged, yes, but even the worst of scars can fade and eventually disappear, if treated right, our environment just needs some help, and some tlc. There is always a choice, we can still save our environment, terraforming mars is at this point, a mere experiment, and does not mean our environment is falling beyond repair
Yes we are doing damage with carbon levels in the atmosphere and the ozone layer depletion, That can all be fixed and we proved that when the ozone had a massive hole in it years ago. However we are not out of our last ice age yet and the ice melt is just because we are nearing the end of it, It may be true we are speeding it up but it would have melted if us humans weren’t a factor. Also the water levels would change however not that much. We do need to fix our environment but in no way are we to far gone.
