The 95-year-old ecologist told leaders of the world’s major democracies that tackling climate change is now a political as well as a scientific challenge.
“We know in detail what is going on on our planet and we know a lot of things we need to do in this decade,” he said in a pre-recorded video address.
As Sir David Attenborough says, we have the skills to tackle climate change, but we need the global will.

“The fight against climate change is today as much a political and communication challenge as a scientific or technological challenge.
a. We have the skills to tackle it on time, all we need is the global will to do it. “
On the final day of leaders’ talks, Sir David called on them to take urgent action to avert a man-made environmental disaster.
The broadcaster and naturalist said the scientific response to the COVID-19 pandemic has demonstrated “how much we can accomplish together when the goal is clear and urgent.”
It comes after various climate groups staged protests across Cornwall to pressure G7 leaders on environmental issues this weekend.
In their conclusions at this weekend’s summit, G7 leaders are expected to commit to cutting their emissions by almost half by 2030 compared to 2010.
It will also include pledges to end almost all direct government support for fossil fuels and phase out gasoline and diesel cars.
And the G7 should also commit to increasing its contributions to international climate finance, helping developing countries cope with the impact of climate change and supporting sustainable growth.
But environmentalists have warned that previous climate finance targets have already been missed and aspirations to conserve 30% of our lands and seas have no form of plan for how areas will actually be protected.
Prior to his address to world leaders, Sir David said: “Today’s natural world is greatly diminished. It’s undeniable.
“Our climate is heating up rapidly. there is no doubt. Our societies and nations are unequal and this is sadly evident.
“But the question that science is forcing us to address specifically in 2021 is whether, because of these intertwined facts, we are on the verge of destabilizing the entire planet?
“If so, then the decisions we make this decade – especially decisions made by the most economically advanced nations – are the most important in human history. “
Meanwhile, Prime Minister Boris Johnson used the summit to launch a £ 500million fund to help countries including Ghana, Indonesia and the Pacific island states tackle unsustainable fishing, protect and restore coastal ecosystems such as mangroves and coral reefs, and reduce marine pollution.
“Protecting our planet is the most important thing that we as leaders can do for our people,” he said.
“There is a direct relationship between reducing emissions, restoring nature, creating jobs and ensuring long-term economic growth.
“As democratic nations, we have a responsibility to help developing countries reap the rewards of clean growth through a fair and transparent system.
“The G7 has an unprecedented opportunity to lead a global green industrial revolution, with the potential to transform the way we live. “
