Not everybody likes mangroves – in places like Thames and Tauranga they’re regarded as a marine weed by some locals. Others believe mangroves may be important for protecting coastlines from surges and sea-level rises as the climate changes. Coastal zone management specialist Professor Karin Bryan of Waikato University talks about whether mangroves are friend, foe or a bit of both. She says NZ really needs to protect its mangroves and develop a wetlands management policy.

Workplace stress and anxiety has risen sharply in recent years so what role should employers play to change that?  Associate Professor Bevan Catley, of Massey's Healthy Work Group, is delivering a series of free public talks, alongside Professor Tim Bentley and others,  on what organisations can do to create workplaces that are better for people and consequently better for productivity. Massey has also launched a New Zealand Workplace Barometer Project to get some firm data on issues of concern in the workplace. He says the Diversity Works awards are good examples of how to get things done in the workplace.

Details of the events on October 16 (Auckland), October 17 (Wellington) and October 18 (Palmerston North) can be found here.

CRISPR-Cas gene editing lets scientists co-opt the immune system of bacteria and use it as a tool – a pair of microscopic “scissors” – to edit the DNA of living organisms, up to and including us. It promises new, more productive crops and unprecedented ways to treat diseases. But are we ready for its broader implications? Ahead of a discussion at Auckland Museum this week, University of Auckland philosophy professor Tim Dare talks about the ethical considerations in seamlessly editing life itself. He also talks about his work with the Ministry of Social Development to develop privacy, human rights and ethical review processes for proposed uses of client data.

The government is due to receive a panel's report from its Inquiry into Mental Health and Addiction by 31 October. It's an area well research by journalist and author Johann Hari for his critically acclaimed book "Chasing the Scream: The First and Last Days of the War on Drugs". Hari was in NZ recently speaking at the Cutting Edge conference in Rotorua. He says there's no silver bullet for rehabilitating an addict, but a wealth of evidence to suggest good old-fashioned human connection and a reason to get out of bed in the morning can make a difference. Another of Hari's books, Lost Connections, about depression, was released this year: it also emphasises the importance of human connections. Wallace talks to him ahead of Mental Health Awareness Week.
