Watch this: Xiuhtezcatl Martinez addresses presidential candidates

Xiuhtezcatl Martinez

Xiuhtezcatl Martinez has spent longer working towards climate change action than most – and he's still only 16.

Here he addresses US presidential candidates Hillary Clinton and Donald Trump on behalf of the millions of Americans too young to vote, but who will suffer the effects of climate change directly if the new government doesn't take immediate steps.

Xiuhtezcatl, a member of youth activist group Earth Guardians, is frustrated by the politicalisation of climate change – an issue that crosses party lines and needs a unified approach.

There's also a petition demanding Clinton and Trump make climate change a major part of their campaign platforms and take urgent action to meet the commitments agreed in Paris.
