On this week's program:

Michael's essay: Re-thinking our relationship with animals

"It may have started years ago when I interviewed Peter Singer, the philosopher and professor at Princeton University. His argument was simple and stark: human animals and animal animals are equal because they can each suffer pain and  experience enjoyment."

How 'micro-data' are being used to influence Canadian voters, and how that's changing our democracy

Cambridge Analytica's use of personal information from tens of millions of unwitting Facebook users, makes it clear: democratic politics has changed forever. Michael talks to Jennifer Robson of Carleton University.

A paean to the old-fashioned pocket hanky

For hygiene, for elegance, for so much more! John J. Boyd explains why it's essential to always have a good-sized cloth handkerchief at the ready.

From roof to table -- How 'data nerds' are transforming Quebec's produce markets

Mohamed Hage and Lauren Rathmell are greenhouse pioneers and agri-biz stars. Their company, Lufa Farms, specialises in growing vegetables on Montreal rooftops. For them, hydroponics, economy and ecology go hand-in-hand.

Meet the nun who pushes corporations to be socially responsible

Sister Nora Nash has taken a vow of poverty, but she can hold her own in corporate boardrooms. She and her fellow nuns at the Sisters of St. Francis in Philadelphia are on a mission to convince companies like General Electric, ExxonMobil and Wells Fargo to care as much about the environment, income inequality and other social issues as they do about the bottom line.

David Grossman: 'Israel is a fortress, but not yet a home.'

Grossman spoke to Michael in front of an audience at the CBC's Glenn Gould Studio. On April 19th, he was awarded his country's highest civilian honour; the 2018 Israel Prize for Literature.
