Growing up on our estate, we were all different colours, but we were all really poor. I never really realised that black was a problem for some people.

Chewing Gum' is kind of like the world I wish I grew up in. There wasn't really a sense of community growing up.

The acting world is tough. It's competitive - and even more so for women - but actually, for black female actresses, the issue isn't really that it's competitive: it's that there just aren't enough roles for them in film and TV.

The unpredictability of the weather, the increasing possibility of intelligence introducing a species more powerful than ours, the growing uncertainty that animals can or should be slaughtered for our pleasure, has led many of us to start asking more complex questions about what is and isn't normal.

The stories that engaged me as a kid were all science fiction. Later, it turned out that I didn't have the language to talk about what was bothering me in a way that was straightforward.

Most kids at 10 or 11 love science, but I never outgrew it.

Being a 'global citizen' is not something reserved for the global elite anymore. Thanks to the democratising power of technology, it's not a trend determined by privilege or even age but by attitude.

I swear on everything holy I do not know what's on the Internet about me.
