Recent research has revealed evidence for a large explosive eruption from the crater about 300 years ago Follow @simonnorfolkstudio for updates, outtakes, unpublished and archive material. @natgeo @simonnorfolkstudio #photojournalism #documentaryphotography #simonnorfolk #stratovolcano #volcano #Koryaksky #Opala #Опала #volcanology #Kamchatka #камчатка #instagramrussia #photooftheday #fineartphotography #seetheworld #igtravel #lensculture #visualarchitects #instagramrussia

Image by @beverlyjoubert. The Makgadikgadi salt pans in Botswana form a harsh, blindingly white and inhospitable environment where the sun beats down onto salt-encrusted earth. Only the toughest animal species pass through here in the dry summer months. But when the rains come, the dust is settled, the sky is mirrored in the shallow pans, nutrient-rich grass grows around the edges and zebras appear in vast numbers. This is an ancient migration from the Okavango and one that was thought to be lost following the erection of wildlife fences in the 1960s to keep wildlife and livestock separate. In 2006 the Nxai Pan fence was removed. It had previously completely blocked access to the pans along these migratory routes and zebras and wildebeest hadn't been able to follow the rains to renewed grazing grounds. Remarkably, despite numerous generations unable to migrate, the removal of the fence immediately resulted in the zebra descendants following those same paths once again. As human activity has interrupted numerous migrations across the world, it is important to know that if we remove barriers, it is possible that these ancient routes will revive and animals will connect important ecosystems seasonally once again. #botswanamigration #zebramigration #makgadikgadi #ancientpaths #aerial #migration

Photo by @adamfergusonphoto | Children play on Beniamina Island in Choiseul Province, Solomon Islands, June, 2018. Islands in the area, predominantly inhabited by seaweed farmers, are eroding due to rising sea levels. The surrounding seas have risen about 7 to 10 millimeters per year since 1993, roughly three times today’s global average — and what scientists expect across much of the Pacific by the second half of this century. @adamfergusonphoto #adamfergusonphoto #globalwarming #solomonislands #risingseas #conservation

photo by @chamiltonjames / Charlie Hamilton James – Naptian checks his phone in the early hours of the morning on the banks of the Talek River in Kenya's Masai Mara Reserve. Cell phones have proved invaluable to young Masai men when herding cows at night as they allow them to send messages to each other detailing locations of lions, which need to be avoided as they have become specialist cow hunters. Conflict between lions and the Masai in the region often results in the death of lions – which are poisoned using cheap pesticides. Cell phones are just one way to help avoid conflict but the bigger issues of over grazing and human encroachment in the region persist.
