Venezuela's food shortages, inflation and crumbling medical sector have become such a source of anguish that a growing number of young women are reluctantly opting for sterilizations rather than face the hardship of pregnancy and child-rearing. Traditional contraceptives like condoms or birth control pills have virtually vanished from store shelves, pushing women towards the hard-to-reverse surgery. While no recent national statistics on sterilizations are available, doctors and health workers say demand for the procedure is growing. (Photo by Carlos Garcia Rawlins/Reuters)

A worker makes auto parts on a machine inside a workshop in Faridabad, India, December 24, 2015. Car makers such as Maruti Suzuki India and Hyundai Motor see huge growth in India, set to become the world's third-largest auto market by 2020 as millions buy their first new car. Price tags can be as low as $3,000 for a new Tata Motors Nano mini-car. India is also becoming a low-cost export hub for global car makers such as General Motors and Ford Motor. As the sector expands, some of the work is sub-contracted out to small factories operating on paper-thin margins, where poor contract workers often have little or no access to safety equipment or health benefits.

These stunning pictures show a normally vicious tiger calmly swimming in a pool of algae, on Jule 9, 2014. The powerful cat takes a refreshing break by taking a dip in the bright green algae. But it looks like this big cat is scared of getting his head wet as he strains to keep it above the water. After splashing around for a bit the tiger gets out and tries to air-dry with specks of the vegetation dripping off his fur. The striking pictures were taken at Copenhagen zoo by snapper Soren Lundgren Neilson. (Photo by Soren Nielsen/Caters News)
