The equation is very simple: without bees there is no food. Without food, human beings risk extinction. In Greenpeace's new video — for the occasion rebranded as Greenbees (green bees) — a group of activist bees are seen trying to convince human beings to stop using pesticides and other toxic substances in agriculture. For their own good. Because without bees there is no pollination. Without pollination, nature cannot offer its wonders, from flowers to fruit to food. A free economic value estimated at 22 billion euros a year.

Recently, the International Union for Conservation of Nature warned European countries about the threats posed to pollinating insects by intensive farming, pollution and the negative consequences of global warming. Of 68 species analysed, 24 per cent are at risk of extinction.

The final scene of the video is emblematic: two bees hand out leaflets while holding a sign reading "Save the humans". Give bees a chance — because, as the closing slogan goes, if we don't give bees a chance, we won't have one either.
