Future Tense

As Earth’s upper atmosphere becomes more congested, it’s also becoming more polluted, and the impact could be dire. Also, why doing without could make for a fuller future; and what’s behind China’s ban on really tall buildings?

Pollution has long been seen as a health problem, but increasingly its being redefined as an opportunity cost to both individuals and society -  and as a burden on future generations.

This podcast explores the essential role of rare earth elements in modern technology, highlighting their global distribution and diverse applications. It also discusses the environmental and social challenges of mining critical metals and the potential of e-waste recycling to meet future mineral demands.

Most of us are healthier, wealthier and better educated than ever before. We have greater access to knowledge and expertise than any previous generation. So, why do humans keep doing stupid things? And why is the world awash with conspiracy? Have we already passed “peak intelligence”? And if so, what can we do to ensure a smarter future?

Responses to climate change are often marked by frustration as much as fear. Those seeking to end our fossil-fuel dependency are increasingly turning to litigation to force the hands of companies and governments - often on human rights grounds. But do the courts have a legitimate role to play in leading the way? Or is this a form of judicial activism?

Stories like opinions have become a necessity of modern life.  Everybody is encouraged to have an opinion and everybody – in the vernacular of countless motivation speakers – is encouraged to be the “hero of their own story”. But are we in danger of making too much of them? If the story becomes the central device for much of our communication, do we risk losing our sense of objective reality? 

Some animals, like sea sponges, can live for hundreds, perhaps thousands of years. They also never get cancer. Understanding why that’s the case has led scientists to question conventional notions of ageing. The idea that future humans may never grow old now seems theoretically possible.

Rewilding is a conservation approach based on the reintroduction of lost animal species to their natural habitats. Its original manifestation was controversial because it centred on apex predators like wolves. But the approach has matured and advocates believe it now has a crucial role to play in securing future biodiversity levels.

Despite increased safety features, policies and content moderation practices, social media platforms continue to be sites where people perpetrate and experience harm. A new approach to platform governance called Transformative and Restorative Justice could help address the underlying causes of harmful behaviour and promote safer and more inclusive digital communities.

When the global pandemic struck the world’s major cities were plunged into silence. But were they? New research casts doubt on just how quiet it really got when people were suddenly forced from the streets. It adds to our complex understanding of noise and sound and how both will shape our future.
