Veteran environmentalist James Lovelock reflects on his career and the planet's future, as he turns 101 years old. The independent scientist, Wollaston medal recipient and inventor of the Gaia Hypothesis sits down with the BBC’s Chief Environment correspondent Justin Rowlatt to talk about his humble upbringing between the two World Wars, his inventions that helped propel the green movement, as well as his thoughts on the over-specialisation of the university system, and the future of human life on Earth.
