$54 trillion a year
— Estimated upper value of the world’s natural capital and ecosystem services, according to ecological economist Robert Costanza
It was a warm autumn day, and the ecosystem service providers were buzzing in the natural capital. The foliage was consuming the light. Anders was sitting in his usual chair. Sophie and Sasha were on their way, and this afternoon he would go with Sasha to an area of outstanding natural beauty to forge a closer familial connection while recreationally walking.
No, that was not correct. Anders rubbed his head with his thumb. It wasn’t an area of outstanding natural beauty, it was twelve hectares or thereabouts of medium to low quality indigenous fauna habitat, but Sasha need not be concerned about that. Sasha was nine years old. The place was pretty – yes, it was pretty – its cultural and recreational value was adequate for their purposes, and such qualitative definitions, he thought, were not of importance to children.
Such definitions were not of importance. Anders closed and reopened his eyes. He gazed at his trouser legs stretched across the patio, and then at the pebbles around the lawn and the trees beyond the garden. The trees were mostly rowans and oaks, and during a night of sleeplessness that had occurred some months ago he had calculated the value of each to about six hundred ecos a year – taking into account such factors as sequestration of atmospheric carbon, electricity conservation through shading and wind reduction, interception of particulate matter, and raising property values through leaf surface area. He looked at them now, doing their part. It was a ballpark estimate, and something about it bothered him now. The leaves were moving in the light. He rose from his usual chair and took a few paces, frowning.
