A view of a sunset in the resort island of Boracay, Philippines, 26 April 2018. The Philippines' famous Boracay island was closed to the public for six months, on April 26, for sanitation and development work at the tourist destination, which the country's president had called a “cesspool”. Beginning at midnight, authorities banned visitors entry to the island, located about 300 kilometers (186 miles) south of Manila, the Department of Environment and Natural Resources reported. In February, President Rodrigo Duterte called the resort a “cesspool” because of its water contamination and later ordered the total closure to the public for six months to resolve environmental issues.

In this May 23, 2018, photo provided by Chris Stewart the sun sets through “vog”, or volcanic smog, in Kailua-Kona, Hawaii. Kilauea volcano on Hawaii’s Big Island has had it all over the past three weeks: molten rock shooting toward the sky, lava oozing from the ground and ash clouds rising miles into the air. You can also add “vog” to the mix. Retired photojournalist Chris Stewart says there’s one good thing about vog: It intensifies the colors of a sunset. But it depends on how thick the haze is. “Some days it’s thin enough you can see the sun passing through”, he said. “But other days we just go inside because we can’t see it at all”.
