By 2050, half of the world's population will suffer from allergies. This isn't just a statistic—it's a looming health crisis that threatens to reshape how we live in our cities. In the UK alone, 13 million people already struggle with pollen allergies, costing the NHS over £1 billion annually and resulting in 5.7 million lost working days. The root of this problem lies in our outdated monitoring methods: specialists still count pollen grains manually under microscopes, using techniques that haven't changed since the 1960s. This antiquated approach means people receive delayed, generalized data that fails to reflect the real-time conditions in their immediate environment.
