Prince Charles has warned we are "rapidly destroying" biodiversity across the planet.
In a message to mark Earth Day, the Prince of Wales said: “Air, water, soil and landscapes are vital to human health and wellbeing.
“Biodiversity, the incredible interconnectedness of plant, animal and insect, life, which we are rapidly destroying, holds insights and solutions that we have yet to discover.
"Its protection and genuinely sustainable management is vital to our survival as a human species."
He added that caring for the planet is intrinsic to caring for our species.
“It is, therefore, increasingly clear that when we care for our planet we fundamentally care for ourselves," he said.
Earlier on Wednesday, climate activist Greta Thunberg released a video to mark Earth Day showing a family calmly getting ready for the day while their house burns down as a symbol of the threat of climate change.
The video references Ms Thunberg's statement at the World Economic Forum in Davos last year, when she told delegates: "I want you to act as if our house is on fire. Because it is."
