SAN ISIDRO, PUERTO RICO - OCTOBER 17: A resident (L) pleads with others to make room as U.S. soldiers prepare to pass out food and water, provided by FEMA, to residents in a neighborhood without grid electricity or running water on October 17, 2017 in San Isidro, Puerto Rico. The food and water delivery mission included U.S. Army, U.S. Coast Guard and Puerto Rico Hacienda forces. Residents said this was the first official governmental delivery of food and water to the community, nearly four weeks after the hurricane hit. Puerto Rico is suffering shortages of food and water in areas and only 17.7 percent of grid electricity has been restored. Puerto Rico experienced widespread damage including most of the electrical, gas and water grid as well as agriculture after Hurricane Maria, a category 4 hurricane, swept through.

Residents wade through flood waters from Tropical Storm Harvey in Beaumont Place, Houston, Texas, U.S., August 28, 2017. Jonathan Bachman: "It was my first day covering Hurricane Harvey. I only made it 500 yards into Houston when I came across a staging area where ordinary people were conducting water rescues in the Beaumont Place neighbourhood of Houston, TX. In addition to the rescues, residents were able to walk against the current down a long road which is seen in the image. At first I went out on a boat with a couple from Louisiana to help and document several rescues. When we got back, I looked down the road and saw an almost perfect line of residents making the long walk to the staging area. I intentionally moved to a position so I could photograph them in a way that would convey the magnitude of this storm. I wanted to communicate that it was a never-ending line of residents struggling to get to safety and it would go on for days. Harvey was a very difficult and emotionally taxing assignment. My first instinct was to put down the camera and help. It is always hard to come to the realisation that I am most helpful when I am taking pictures. As an observer of suffering you have to believe that your images can make a difference." REUTERS/Jonathan Bachman/File photo SEARCH "POY STORY" FOR THIS STORY.
