This week we have images of a Chilean volcano, migrants shipwrecked in the Mediterranean, the "Blue Forest" in Belgium,  Kim Jong Un atop Mt Paektu, the Boston Marathon, Orcas hunting on a Patagonian beach, Saudi attacks on Yemen, tule elk along California's coastline, and much more.

• A herd of tule elk leap over a fence in Point Reyes National Seashore, California. The herd moved warily along a California coastal hill as a herd of Black Angus cattle graze nearby. Despite the apparent peaceful coexistence, the animals are at the center of a battle for precious grasslands reduced by the state's drought. Ranchers and farmers who live and work within Point Reyes National Seashore want the free-roaming elk fenced in so their livestock do not have to compete for grass. Wildlife advocates and many park users are opposed after almost half of the majestic elks died while living in a fenced-in area in the northern part of the park.

The suppliers with the highest per capita water use would have to accept a 36 percent cut. Meanwhile, environmentalists and some urban dwellers say the state's $45 billion agriculture industry should bear a greater share of water savings, given its massive water use.

네팔 강진: Nepal After the Earthquake

ALAN TAYLOR

A magnitude 7.8 earthquake struck Nepal early on Saturday, centered 10 miles below the surface, less than 50 miles from the capital of Kathmandu. As many as 3,700 have been killed by the quake and subsequent avalanches triggered in the Himalayas. Historic buildings and temples were destroyed, leaving massive piles of debris in streets as rescue workers and neighbors work to find and help those still trapped beneath rubble. Below are images from the region of the immediate aftermath of one of the most powerful earthquakes to strike Nepal in decades. (Editor's note, some of the images are graphic in nature.)

지구의 날 제45주년: Earth Day 45

ALAN TAYLOR

First organized in 1970, Earth Day is a day set aside to remember and appreciate the Earth's environment, and our responsibilities and roles within it. Today, April 22, we observe the 45th annual Earth Day, and though many things have changed for the better, environmental challenges remain. In the past 45 years, the population of the Earth has doubled—75 percent of the people alive today were born after 1970—and the increased demand on our limited resources makes sustainable solutions even more important. Collected here are 45 images of our world from recent years, each a glimpse into some aspect of our environment, how it affects and sustains us, and how we affect it.

As the sea levels around the globe rise, researchers affiliated with the National Science Foundation and other organizations are studying the phenomena of the melting glaciers and its long-term ramifications. The warmer temperatures that have had an effect on the glaciers in Greenland also have altered the ways in which the local populace farm, fish, hunt, and even travel across land.

• Mountains of used tires lay in a dump in the countryside in Sesena Nuevo, near Madrid, Spain, on September 24, 2014. The dump site in Sesena is a major environmental problem and was declared illegal back in 2003. It currently stores over 75 tons of tires. The company which ran it was penalized heavily, finally walking away. Now the regional government has started to process the tires in order to clear the area within approximately four years. Most of the material will be recycled for building materials, surfacing for roads, sports tracks, and children's playgrounds.

The luminescence, also called Sea Sparkle, is triggered by farm pollution that can be devastating to marine life and local fisheries, according to the University of Georgia oceanographer Samantha Joye. Noctiluca itself does not produce neurotoxins like other similar organisms do. But its role as both prey and predator can eventually magnify the accumulation of toxins in the food chain, according to the oceanographer R. Eugene Turner at Louisiana State University.

• An aerial view shows a tract of Amazon rainforest which has been cleared by loggers and farmers for agriculture, near the city of Santarem, Para State, on April 20, 2013. The Amazon rainforest is being eaten away at by deforestation, much of which takes place as areas are burnt by large fires to clear land for agriculture. Initial data from Brazil's space agency suggests that destruction of the vast rainforest—the largest in the world—spiked by more than a third over the past year, wiping out an area more than twice the size of the city of Los Angeles. If the figures are borne out by follow-up data, they would confirm fears of scientists and environmental activists who warn that farming, mining, and Amazon infrastructure projects, coupled with changes to Brazil's long-standing environmental policies, are reversing progress made against deforestation. Environmental issues will be under the spotlight as a United Nations Climate Change Conference opens in Warsaw, Poland, on November 11. This picture was taken on April 20, 2013.

• Members of the glaciology unit of Peru's national water authority walk on the Pastoruri glacier in Huaraz, Peru, on Thursday, December 4, 2014. The glaciology unit is studying the measurement of ice thickness. According to Alejo Cochachin, the coordinator of the glaciology unit, the Pastoruri glacier retreated 576 meters between 1980 and 2014. Peru's glaciers have lost more one-fifth of their mass in just three decades, and the 70 percent of Peru’s 30 million people who inhabit the country’s Pacific coastal desert, depend on glacial runoff for hydropower and to irrigate crops, meaning their electricity and long-term food security could also be in peril. Higher alpine temperatures are killing off plant and animal species in cloud forests, and scientists predict Pacific fisheries will suffer.

• In this photo taken on Friday, June 15, 2012, a pig eats from a trash-ridden creek that runs towards the conference center where the United Nations Conference on Sustainable Development, or Rio+20, takes place in Rio de Janeiro, Brazil. The throngs streaming into Rio for the Earth summit may be dreaming of white-sand beaches and clear, blue waters, but what they are first likely to notice as they leave the airport is not the salty tang of ocean in the breeze, but the stench of raw sewage.

• Rocinha favela, or community, the largest favela in Rio, stands behind a mountain in an aerial view on February 24, 2015, in Rio de Janeiro, Brazil. Rio marks its 450th anniversary on March 1 and is celebrating the event with a yearlong series of events including concerts, exhibitions, historical tours, soccer matches, fireworks displays, and other activities. The "Marvelous City" was founded in 1565 by the Portuguese and was the seat of power of the Portuguese Empire in the 19th century before serving as the capital of the Brazilian Republic until 1960. The city is Brazil's most popular tourist destination and will host the Rio 2016 Olympic Games, the first to be held in South America, next year.

• A man working at an illegal oil-refinery site pours oil under a locally made burner to keep the fire going, near River Nun in Nigeria's oil state of Bayelsa on November 27, 2012. Thousands of people in Nigeria engage in a practice known locally as "oil bunkering"—hacking into pipelines to steal crude then refining it or selling it abroad. The practice, which leaves oil spewing from pipelines for miles around, managed to lift around a fifth of Nigeria's 2-million-barrel-a-day production last year according to the finance ministry.

• Homes with swimming pools are seen in the Palm Springs area, California, on April 13, 2015. The average daily-water usage per person in Palm Springs is 201 gallons, more than double the California average. California's cities and towns would be required to cut their water usage by up to 35 percent or face steep fines under proposed new rules, the state's first-ever mandatory cutbacks in urban water use as the state enters its fourth year of severe drought. Communities where residential customers use more than 165 gallons of water per person per day would have to cut back by 35 percent. This picture was taken on April 13, 2015.

• In this November 11, 2014, photo, policemen stand guard on the perimeter of a crater created by gold mining during an occupation of an illegal gold-mining camp as part of an operation to eradicate the camps in the area known as La Pampa, in Peru's Madre de Dios region. Less than a month before Peru plays host to global climate talks, the government sent a battalion of police into the southeastern jungles to dismantle illegal gold-mining camps. In addition to contributing to deforestation, the illegal alluvial gold mining contaminates the jungle with tons of mercury.
