Our planet is a small miracle of true Goldilocks proportion. Suspended between two 'Earth Like' bodies we represent the sum of these extremes.
Mars. Cold and empty of useable atmosphere, may hold potential as a next destination. It has had water and may do still. Unlocking it may be a 'Fire and forget' mission for a small bunch of instantly famous scientists. The environment is tamable. The cost may be a one way ticket however.
Venus. Hot to vapourising point. Wet to saturation point but no rain falls as the preciptate Sulphuric Acid boils off before hitting the ground.
Our porridge is just right. Our beds and chairs are just so. It would be good if we found ourselves in this fortunate position by dint of greater awareness of the comparisons with our neighbours.
Exploration has more value than the push to colonise. It may provide the shove necessary to wake us up to our responsibility to this planet. Why try to escape? The bears aren't yet home.
