(CNN) — Emperor penguins releasing millions of micro-bubbles from their feathers, children’s dresses hanging from a clothesline on a porch in Puerto Rico, and students standing among fountains in kyiv are all works by National Geographic photographers which are on sale to support Ukraine.

The print flash sale, which will run until April 20, was organized by Vital Impacts, a non-profit organization that supports local groups that protect human and wildlife habitats.

Vital Impacts has partnered with National Geographic photographers to sell their work, with 100% of proceeds going to Direct Relief, a humanitarian organization currently working in Ukraine to provide medical aid to people affected by war.

Vital Impacts said its latest sale for conservation initiatives raised $620,000. The organizers hope that it will exceed the million dollars.

“We can all watch the horrors of the world from afar and feel so helpless, but this is a way to support humanitarian efforts and have a unique opportunity to purchase some of the most memorable art prints from the greatest photographers of the world,” said photographer Ami Vitale. , co-founder of Vital Impacts, told CNN.

“The hope is that this work will inspire all who see it to work for a world of peace and compassion.”

The collection includes breathtaking underwater images, as well as photos of incredible landscapes and intimate human moments captured on camera.

There’s also a mix of “eccentric and intellectual” imagery and “painfully beautiful” historic moments, Vitale added.

“There’s something for everyone,” Vitale said, “and we hope these impressions will inspire people to believe and work for a better world.”
