Unfortunately, this progress has come at a cost. Carbon emissions have tripled since 1960. We are now consuming about 1.75 times as many natural resources in a year as the planet can possibly regenerate – which is driving land and biodiversity loss, resource shortages and climate change. This is not sustainable, especially with the global population forecast to increase by a further 50% this century. And although people are living longer, they’re not always healthier or happier: there’s been an increase in chronic disease, while mental health issues are also on the rise.
