There are too many people!
We are destroying the natural environment (chopping down the forests, butchering the wildlife)
We are polluting the planet.
There is too much superstitious nonsense and fanatical religion.
There are so many conflicts and war.
Reduce the population.
Improve efficiency of technology.
Create efficient green energy
Stop chopping, slaughtering and despoiling and give 50% to wilderness
Stop dumping effluent.
Create more efficient crops.
Put all the religious stupidity in the past where it belongs.
Stop the politicians and billionaires running the place with their endless growth, expansion, greed and selfishness.
Set up a new positive zeitgeist!
