Well since it's literaly us vs the planet (since we seem to be unable to regulate our society's consumption of finite resources), the question is : does the planet exist for us to consume it ?
The answer is no, but we'll still consume it.
Do we deserve to live ? Well outside of society, there is no reason we're deserving it more than any living being. And sometimes I clearly wonder, when some individuals contribution is a big negative legacy for the next ones, and to the planet.
Tbh I do not mean we (humans) do not deserve to live, but I clearly wouldn't want it taken for granted, cause it is not.
