Cartoon showing a bicycle on the edge of a cliff. A giant iron ball filled with factories, smoke stacks and pipelines is attached to the bicycle by a large chain and hangs over the cliff. The person on the bike is desperately pedaling to avoid being dragged over the cliff. A sing pointing away from the cliff reads 'climate goals'
