"As far as we know, there is exactly one planet in our Solar System – and the
galaxy – which hosts life. And you’re on it.
For the first 800 million years, Earth was dead. Then life began making itself
at home. For over three billion years, lifeforms have helped shape their own
environment. Earth’s energy balance (commonly known as the climate) and its
interactions with trillions of species is the main determinant of environmental
conditions.
As you know, one species – ours – is exceptionally good at changing our
environment to suit us. The problem is, we’re now too good at it. We chop down
forests, remove mountains to get at ore bodies, take over grassland, fish out
entire seas, create and unleash novel chemicals and pump huge quantities of
nutrients from fertiliser into the system. These and many more undermine the
hidden life support system on which we rely."
