Conservative UK radio host tries to own a climate activist and it goes horribly wrong

A climate activist group called Insulate Britain has been causing havoc in the U.K. for the past six weeks by blocking major roads to promote its climate agenda. Since mid-September, 146 members have been arrested 690 times.

Some members of the group have gone so far as to glue themselves to the streets to stop police from arresting them.

While their tactics may seem a little extreme, their message is not. The group has a very practical plan to help the country lower its emissions to combat climate change. It is calling on the government to fully insulate all 29 million homes in Britain by 2030.

"Nearly 15% of the UK's total emissions comes from heating homes: an overhaul of the energy performance of the UK's housing stock is needed to reduce the energy demand," the group says on its website.

Cameron Ford, a spokesperson for Insulate Britain, appeared on conservative host Mike Graham's talkRADIO show to discuss climate activism and it ended with the show's host making a bizarre claim about concrete.

Ford is a carpenter.

GRAHAM: You work with trees that have been cut down, then, don't you.

FORD: It's a sustainable building practice.

GRAHAM: How is it sustainable if you're killing trees?

FORD: Because it's regenerative. You can grow trees, right?

GRAHAM: Well, you can you can grow all sorts of things, can't you?

FORD: Well, you can't grow concrete.

GRAHAM: You can.

Then after seven seconds of awkward silence, Graham ended the interview.

After the exchange went viral, Graham was dubbed "Mr. Concrete" across social media.
