In the UK, we are now at the end of the big Easter period of action for Extinction Rebellion. It hit the headlines big time, got everybody talking. So was I right or wrong in my previous video, where I said that their approach was hurting, not helping?
More importantly, what was the rather surprising element I learned since that video that most of the general public don't know, and even a good portion of those that took part in the protests probably don't either?
Socially responsible businesses want to provide equal opportunities for all their employees. And even those that don't much care about their social responsibilities have to obey the law, which rightly makes it illegal to pay men and women different rates for completely comparable and equivalent jobs.
Many modern protest movements claim inspiration from the great movements of the past - specifically those led by Gandhi, Martin Luther King and Nelson Mandela. But they consistently fail to learn the lessons of those historical successes.
One side on the climate change debate thinks that the science is completely on its side. The other side thinks that it's faked, or misrepresented. Neither side is following the evidence and then forming its opinion, because that's not how our brains work!
More and more the environmental movement is using children - sometimes as young as 6 years old - to voice its messages and front its campaigns. Is this a powerful device, likely to win over sceptics and waverers? Or it is exploitative and counterproductive? We discuss.
According to a new report, Americans expect companies to take stands on issues. But does that go all the way to wading into contentious party-political issues, and identifying with one side or other of a polarised country?
Recently the EAT Lancet report suggested that there is an ideal diet for 10 billion people on the planet by 2050, and it's one with minuscule amounts of meat, and way more of everything else. With the challenges of climate change, how we sustainably feed ourselves is a huge question.
At the recent UN summit, 15-year-old Greta Thunberg said that grown-ups had messed up the world. In this video, I try to give a different perspective - one that goes to common ground, rather than turning important issues into "us versus them".
