Canada's Minister of Environment and Climate Change Catherine McKenna discusses the effects of climate change with retired astronaut, Commander Chris Hadfield.

Mr Hadfield has had a storied career which began with the Royal Canadian Air Force.

He was the first Canadian to walk in space and has flown two Space Shuttle missions and served as commander of the International Space Station.

Mr Hadfield talks about how he witnessed climate change and its impact from space, such as how the Aral Sea is visibly smaller.

The Aral Sea was once the fourth largest sea in the world but has been shrinking since the 1960s and is now only 10% of its original size.

Mr Hadfield says that people's actions are part of the solution to help reverse climate change. 

Canada is striving to ensure that everyone, including its young citizens, are engaged on clean growth and climate change initiatives.

Young people are powerful agents of change. Sharing the work of students who are finding solutions to climate change encourages more youth to get involved and take action.

Climate change affects everyone and young people are finding new ways to make a difference in their communities.
