Pandemic has made us value our perfect planet and find support from nature, says Attenborough

"The idea of devising this series as we did is to show how well the planet works with these forces, how they shape the planet and how left to their own devices, it's a very perfect system.

"Just showing what we're doing to destroy it would have been a wasted opportunity, now is such an amazing opportunity for people to appreciate how our planet works and how we're working to destroy it, but equally, what are the solutions for how we can turn it back into a perfect planet."

In dark times, he said, he hoped the program was honest but also optimistic in its tone.

"These are the forces of nature that shape our planet and we as humans destabilize it－but the solutions can be found in these forces," he added.

"Thermal, tidal, wind, solar－these are the energy sources of the future. We need to move away from fossil fuels and take up these new systems. What I've learnt is that we can get back to the perfect planet we've been losing over the last few decades."
