The way I see it, humans have great potential but also great stupidity. And at this point, due to major exponential population growth which is causing resource depletion and mass extinction of supporting species, humans have two options: we can work together as a species towards a common goal, or we can continue fighting amongst ourselves. What I would like to discuss here is which goal(s) would be best suited to our species and the best use of our potential, rather than the chances of actually agreeing as a species to accomplish a clear goal.
Below are some examples of common goals that the human species could agree to achieve. Feel free to add to this list, or comment on what I have here.
Total Destruction of Earth
There are many potential ways to achieve this goal and therefore not challenging enough for our species. Although I list it here because we might choose to do this as a last resort.
Intergalactic Space Travel
If this is physically possible, I see no reason why humans with enough mental and physical flexibility couldn’t at least make it out of the solar system. It might require genetic modification of the human species. Somehow we would need to enhance our physical support system while maintaining our mental capacity, a system that would require less food, water, and energy. We would at least need to be smaller, maybe even the size of howler monkeys.
Sustainable Organic Agriculture
With 6.5 billion people on the planet, achieving a state of balance with Ma Earth would be tough to say the least. We would have to simultaneously lower the birth-rate, increase the death-rate, and maintain a much lower consumption of resources (we could still use electricity and fossil fuels if we maintain minimal consumption and use renewables for most of our energy needs). This would be a colossal challenge physically and mentally but it can be done.
We are not limited to any one goal. After we complete one, we could try for another.
