Without denying the major challenges that lie ahead, or glossing over the damage inflicted by Man on Nature, the photographs selected for the fourth edition of the Prince Albert II of Monaco Foundation Environmental Photography Award reveal the incredible beauty of our planet, from the polar regions to the depths of the ocean, or even in the heart of ancestral forests. By looking at our relationship with nature and the close links between human health and the health of the planet, the photographers invite us to take a journey through images and deliver a message of hope: that together we can still take effective action, if we join forces to limit the effects of climate change and promote the resilience of ecosystems.
