Nickelodeon is running a week of environmental programming for what it calls "Greenagers".

The initiative, called Nick’s Big Green Thing, includes an hour-long documentary by adventurer and environmentalist David de Rothschild called Nick’s Big Green Challenge.

A survey for the channel found 95% of four to 15-year-olds said they were concerned about global warming. Three quarters said they knew as much or more than their parents about the problem.

It has labelled the group "Greenagers" and hopes they will be attracted by Nick's Big Green Thing and learn more about "little things that can make a big green difference".

De Rothschild's programme for Nickelodeon sees him challenge children to find evidence of global warming and what can be done to combat it. They then present their findings to environment secretary Hilary Benn.

"It’s great to see that this emerging group of Greenagers are paying attention to the subject of global warming," said de Rothschild. "Our climate's changing quicker than anyone ever expected and we can’t afford to ignore the signs."

Nickelodeon UK managing director Howard Litton added: "These Greenagers are taking their environmental concerns very seriously. As a broadcaster we aim to address serious subjects such as climate change in a fun and engaging way so that kids feel like it is within their power to do something positive about it."

Nick’s Big Green Thing runs from today to Friday and on the Nickelodeon website.
