“Here’s a big number: $44 trillion.
That’s how much of the world’s total economic output is dependent on animals and ecosystems, according to the World Economic Forum. Insects pollinate commercial crops, coral reefs protect coastal buildings, wetlands purify water, and all of those services — and more — help fuel economic growth.
If the economy is embedded in nature, then the global decline of wildlife and ecosystems is a risk for companies and investors alike. If insects vanish from farmland, say, farmers might have to pay to import pollinators or produce less, which hurts their bottom lines. That’s one reason why WEF ranks “biodiversity loss” as the third most severe risk to the economy over the next decade, after failure to act on climate change and extreme weather.”

“Three-quarters of the world’s food crops (and a third of global crop production) depend to some extent on pollination from birds, bees, and many other insects and small animals. And some insect populations have fallen bymore than 70 percent in just a few decades. In fact, there are farmers in California who already pay to import bees because there aren’t enough local pollinators. That could eat into investor returns.”
