It's undoubtedly a long way from coming into reality, but the type of legislation promoted by UK barrister Polly Higgins and her Eradicating Ecocide campaign is at the top of my list of most important legislative and philosophical shifts needed to fully address our current environmental problems.
One small step forward on that has been taken by the Green Party of England and Wales.At the Green Party annual conference a motion was passed giving "wholehearted support for an international law of Ecocide—a crime against nature, humanity, and future generations—to be established and recognized as an International Crime Against Peace."
Such a law would define Ecocide as:
The extensive damage to, destruction of or loss of ecosystem(s) of a given territory, whether by human agency or other causes, to such an extent that peaceful enjoyment by the inhabitants of that territory has been or will be severely diminished.
Again, a long way from such a law being established, but this is the way we need to be thinking about green issues, in a big way.
