So I was thinking about polar bears the other day. They're not my normal topic for musing while dodging London traffic on my bicycle, but I was thinking about them because a friend told me something I just couldn't believe. She said that polar bears could be the first mammals to lose their entire habitat to climate change. I was shocked. Polar bears have no natural predators. They're on the top of the food chain. They're perfectly adapted to the inhospitable Arctic environment, but now their icy home is disappearing beneath their paws because of our carbon polluting lifestyles.

Hi, I'm Katie and I work in the fundraising department here at Canonbury Villas. In some ways, it's like most office jobs, including long hours filled with meetings, what sometimes feels like days staring at spreadsheets and fielding countless sales calls from people convinced their product, service, magical solution can revolutionise the way I do my job.

It's not exactly rock and roll, but at the same time it isn't just any old office job and Greenpeace certainly isn't any old employer. Plus, I don't think anyone here works simply to progress their career. It's about so much more than that.
