A sign advising to pray for rain hangs above an exhibit area at the 47th Annual World Ag Expo in Tulare, February 12, 2014. About a hundred years ago, when urban water systems were being developed throughout the state, the city of Sacramento wrote protections from metering into its charter, vowing that residents would always have the right to use as much water as they needed. But on Tuesday, the state's top water regulators released a framework for enforcing California's first statewide mandatory restrictions on urban water use – cuts of 25 percent for non-agricultural users ordered last week by Democratic Governor Jerry Brown as a devastating drought enters its fourth year.

The Ivanpah Solar Electric Generating System is seen in an aerial view on February 20, 2014 in the Mojave Desert in California near Primm, Nevada. The largest solar thermal power-tower system in the world, owned by NRG Energy, Google and BrightSource Energy, opened last week in the Ivanpah Dry Lake and uses 347,000 computer-controlled mirrors to focus sunlight onto boilers on top of three 459-foot towers, where water is heated to produce steam to power turbines providing power to more than 140,000 California homes.

A competitor tries to swipe away some grease as he slips off the “gostra”, a pole covered in grease, during the celebrations for the religious feast of St Julian, patron of the town of St Julian's, outside Valletta August 30, 2015. In the traditional “gostra”, a game stretching back to the Middle Ages, young men, women and children have to make their way to the top of a pole and try to uproot one of the flags to win prizes.

A Flemish demonstrator, one of thousands who gathered for a march through Brussels to protest against what the Flemings call their subjucation by the French-speaking Walloons, draws back as he is jeered by a crowd of Walloons on the pavement in a Brussels Street, on October 14, 1962. The Flemish demonstrators clashed with Walloon counter demonstrators as riot police sought to maintain order. The Flemings claim that although they form 60% of the population in Belgium, they are inadequately represented in the government, and they say, the Walloons get most of the top jobs in the armed forces and the diplomatic service.

A Hypsiboas crepitans frog is pictured at a terrarium in Caracas November 30, 2015. Venezuelan frogs and toads are in critical danger due to climate change as rising temperatures complicate reproduction and spread a deadly fungus, say scientists, who liken the species to canaries in a coalmine warning of imminent danger. The survival of a group of nearly 20 frog and toad species, which top Venezuela's list of endangered species, may rest on a small group of academics in a Caracas laboratory attempting to recreate the amphibians' natural reproductive conditions.

Sleep under the Stars, hosted by Hepburn Wind, has given us an opportunity to enrich our daily life with art. Thanks to this festival, a regular wind turbine was turned into a marvelous peace of art. The artwork is especially noticeable, since its theme greatly contrasts with the background behind the wind turbine. Moreover, the idea of drawing a woman-giantess walking over the mountain tops on a large conical object is quite extraordinary. Nevertheless, the grey and green colors of the picture were very well chosen for this particular image. You can only imagine the obstacles that the artists had to face when making a picture on such a large object. However, nowadays, people never cease to amaze with their ingenuity, leaving us gaping in awe at their creations.

Makoto Chino eats a purple haze carrot as he works harvesting the morning's vegetables and fruit from his family's farm in Rancho Santa Fe, California August 12, 2014. The gravitational pull of Chino Farm is legendary. Since they don't ship, everyone – whether a top chef or a traveling foodie or a local resident – comes to the farm stand, simply called “Vegetable Shop”, on a dusty corner of this affluent San Diego County town, hemmed in by sprawling housing estates.
