It was the ultimate บทความสล็อต curveball bedtime question: "Mummy, will we be extinct one day like the dinosaurs?"

Four-year-old Otis had his mum Gerry "stumped" - so the pair came up with a plan to write to nature's oracle, Sir David Attenborough.

And, to their amazement, the 94-year-old sent a handwritten response.

"The answer is that we need not do so as long as we look after our planet properly", Sir David wrote reassuringly.

Gerry, 38, a communications officer for medical research at Cardiff University, said she thought "honesty was the best policy", after Otis had asked the existential question.

"I said I didn't know the answer - but I hoped not. So I told him about climate change and how we need to look after our planet," she explained.

"We also talked about the work lots of amazing people, like Sir David and Greta Thunberg, are doing to make sure people are taking action to make a difference," she said.

"When I explained about global warming, his little eyes were on stalks, but I tried to focus on the small things we could do to help like recycling our rubbish, driving the car less and eating less meat."

They sent their question to Sir David the following morning, with a little card and a dinosaur drawing Otis had made.
