Urban life has not only reshaped what it means to be human, cities are also changing animals. Rats in different parts of New York are evolving separately. Ecologist Rob Dunn describes cities as accelerators of evolution. Also in this episode, how city administrators compete for dominance using the same approach as social media influencers. And why house-flipping has gone algorithmic.

Across the globe single household occupancy is skyrocketing. In some Western cities "singletons" make up almost fifty per cent. But it's a trend that's largely slipped under the radar. Policy makers are yet to catch up with the new social reality. The growing cohort has significant economic potential, but they continue to face stereotyping and discrimination.

The greatest demographic shift in a century is being ignored: single living

Globally, around 300 million people consider themselves "influencers" or professional content creators. In the United States alone the number is approximately 13 million – that's roughly the same size of the US manufacturing sector. It's a precarious profession and the reasons for choosing to become an influencer are many and varied. So, what does their rise tell us about the modern workforce? Also, building islands to create offshore energy hubs; and a warning about the dangers of normalising the abnormal.

It's time to take the Influencer economy seriously

Many of us take actions to improve the environment and make for a better planet. But in a consumerist world where status is all, it can be hard to avoid making choices that negate your original intentions and send you back to square one. It happens in everyday life when picking a car or building a new house. And it happens on a large scale. For example where mass tree-planting occurs in habitats that were never meant to be forested. Shouldn't we know better?

When good intentions fuel further environmental problems

Insecure housing has long-term effects on both individuals and communities, it's impacting the social fabric of countries around the world. Corporations buying up housing stocks are further adding to the pressure. In rich and poor countries alike the cost of housing is outstripping growth in incomes. As a result, more than 100 million people have been made homeless, according to the UN. While more than 1.6 billion lack adequate housing and essential services. We also explore some possible solutions. But the big question mark hanging over the future of the sector remains political will.

Big corporations are taking over as landlords and it's further fuelling the global housing crisis

For more than a decade serious news organisatons, including public broadcasters, have increasingly relied on social media and other third-party digital distribution platforms to reach audiences. But now the big tech platforms are no longer interested in traditional news. So, can public interest journalism survive without the online networks they let cannibalise their content? How can serious news outlets avoid slipping into obscurity? And what impact would such a decline have on our culture and democracy?
