I like the question m1469, so I will add my opinion.
Eternal is formless and One/Indivisible. It creates forms, becomes them in a sense, as no form can exist without formless, but at the same time is still untouchable to anything that happens in the material relative realm/realms, which exist in that Oneness. Of all the life expressions only human form has a conscious consciousness and is a “primary vehicle” for the evolution of consciousness. No other species has the ability to create so much illogic in everything that it does, but at the same time that illogical behavior creates specific path of evolution for the whole planet, on which a particular human form evolves. That evolution is important, as the purpose of this “game” is to evolve the eternal through evolution of consciousness/Life. Eternal is already 100% logical (so no chaos can exist in its laws), as without it no material realm would exist a second. Chaos exist only in a human mind, as it cannot grasp eternal laws that guard the evolutionary process yet.
So, preserving the life as it is now - is to allow for the main goal of Eternal, which each one of us already IS - its own evolution. Most of people on this planet are still not aware of their own BEING and because of this, they are lost in everything material (desires). It slowly changes, and for the sake of preserving Life on this beautiful planet, we should do everything possible to make changes in ourselves, so the life can go on. Why change ourselves? Because everything what we carry inside is projected outside in material realm. Totality of all projections (from each human form) creates life as we see it. To see a meaningful change in what we see in the world, requires only change in what each one of us desires.
I am optimistic long term and think that human form will go on, but pessimistic in short term, as we are fast approaching times of revolutions and big wars - which will deplete numbers to some extend and make life a "hell" for a lot of people left to see it.
