Sir David Attenborough: Climate change 'our greatest threat'Watch
The broadcaster said it could lead to the collapse of civilisations and the extinction of "much of the natural world".
He was speaking at the opening ceremony of United Nations-sponsored climate talks in Katowice, Poland.
The meeting is the most critical on climate change since the 2015 Paris agreement.
Sir David said: "Right now, we are facing a man-made disaster of global scale. Our greatest threat in thousands of years. Climate change. If we don't take action, the collapse of our civilisations and the extinction of much of the natural world is on the horizon.""
Have your say - are we as individuals doing enough to reduce our impact? Are large businesses and corporations doing enough to reduce theirs?
When you see how many people there are in places like India and how many are emigrating across the world then there is little hope that we can sustain this level of population growth. It's killing us all .
- Cut all foreign aid
- Ban cities
- Ban plastic
- Let epidemics run rampant
2. I’d say things like Spanish Flu, the Black Death were a bigger threat. I’d also probably add the Second World War too.
Misguided rather than selfish perhaps ........although the prospect of nuclear war or being hit by a comet is very real . Either way ...if one thing doesn't get you , then something else will . It's just a matter of time . We're doomed ...we're doomed . Theres no point doomsday prepping ....it's still going to get you. ..you might forget to stock toilet rolls or ketchup and then you're really screwed .😨😱😱
