The world is being left “dangerously exposed” to further pandemics due to the rapid destruction of the diversity and interconnectedness of all species, the Prince of Wales has warned.

Charles said he did not need to stress the “planetary emergency confronting us, nor the desperately urgent need for action”.

He made the comments during a speech to the Sustainable Growth 2021 Conference, hosted by Cornwall Chamber of Commerce, on World Oceans Day and ahead of the G7 summit, which begins on Friday.

Other speakers at the online event included Sir Patrick Vallance, the UK Government’s Chief Scientific Adviser, who said there was no “get out of jail free” card to reaching the target of net-zero emissions by 2050.

Charles, the Duke of Cornwall, told the conference on Tuesday: “It is particularly timely that this important virtual event is being held today as we approach the G7 summit on Friday.

“As the eyes of the world focus on this wonderful county, it is encouraging to see that so many Cornish businesses and organisations are already working together to find solutions to the environmental and social challenges we face.

“I hardly need to stress the planetary emergency confronting us, nor the desperately urgent need for action, yet if I may say so, I believe we now find ourselves presented with a unique opportunity to catalyse change towards a sustainable nature-based path here in Cornwall.”

At present, we are rapidly and disastrously destroying the miraculous diversity and interconnectedness of all species of life on Earth

Charles said he hoped the conference would provide an opportunity to see a sustainable operating model for Cornwall in the future.

“It is abundantly clear that Cornish businesses must deliver not just growth but the kind of sustainable growth, genuinely sustainable growth, which gives back to nature in return for what we take from her, and which consequently leaves the next generation the inheritance of a thriving natural environment that is more resilient, and able to deliver a shared prosperity within planetary boundaries,” he said.

“At present, we are rapidly and disastrously destroying the miraculous diversity and interconnectedness of all species of life on Earth, thereby leaving us dangerously exposed to further devastating pandemics.”

Charles described “globally significant” projects taking place in Cornwall that focused on resolving the issues of climate change, loss of species diversity and habitats, particularly in the oceans.

He said these “innovative and exciting” initiatives included floating wind power in the Celtic sea, the use of geothermal power, biomethane for heating and the potential for Cornish lithium to be used for batteries.

Charles added that he was delighted a number of Cornish businesses had taken up his Terra Carta charter, launched earlier this year, which “places nature at the heart of global recovery”.

He described the work of accelerating a green and carbon-free recovery as a “hugely important task” that was “far from simple”.

“However, I’m convinced that it can and must be done and that we must start now as time is rapidly running out on us as I speak,” Charles said.

In his speech, Sir Patrick told how Britain had come through an “extraordinary year” with the Covid-19 pandemic and the challenges it had brought.

“But this challenge is much, much bigger than Covid, it will last much longer and it needs us to do things that will be embedded in everyday ways of working and living if we’re going to achieve it,” he said.

Sir Patrick said the date of 2050, the target for net-zero in the UK, was not far away and much had to be done before it.

“Whatever we do needs to be sustainable, and that sustainability needs to be at the individual level, at the business level and at the societal level,” he said.

“It means that what changes we make have to be affordable and durable.”

Sir Patrick told the conference that innovation would be an “important way” of dealing with adapting to and mitigating climate change, but was “not a free pass”.

“We need to be realistic that anything that isn’t already discovered, is not really going to help us get to this by 2050,” he said.

“It’s things that are discovered that now need to be innovated and implemented that will help us get there. So let’s not dream there’s a ‘get out of jail free’ card.”

The Government has to consider issues such as transport, energy, industry and business, residential and agriculture to meet the target, Sir Patrick added.
