Picture shows algae grown in waste water from companies Novo Nordisk and Novozymes in a facility in Kalundborg, Denmark, November 20, 2015. The Algae can be used to clean water by eating pollutants, for fish feed or its pigments extracted for the pharmaceutical industry. As pioneers of so-called industrial symbiosis, these companies swap waste and byproducts to cut costs and carbon dioxide (CO2) emissions profitably -- an approach that offers big business a financial incentive that could be crucial to nations striving to meet targets agreed at this month's global climate summit. Their success has attracted attention globally, with more than 30 corporate and municipal delegations from 20 countries visiting the town this year, including mayors from China's fast-growing Guandong province.

5-year-old Baraka Cosmas Lusambo (R) from Tanzania holds hands with Elissa Montanati of the Global Medical Relief Fund in the Staten Island borough of New York, September 21, 2015. Albino body parts are highly valued in witchcraft and can fetch a high price. Superstition leads many to believe albino children are ghosts who bring bad luck. Some believe the limbs are more potent if the victims scream during amputation, according to a 2013 United Nations report. Albinism is a congenital disorder affecting about one in 20,000 people worldwide who lack pigment in their skin, hair and eyes. It is more common in sub-Saharan Africa and affects about one Tanzanian in 1,400. United Nations officials estimate about 75 albinos have been killed in the east African nation since 2000 and have voiced fears of rising attacks ahead of this year's election, as politicians seek good luck charms from witch doctors.

Albinism is a congenital disorder affecting about one in 20,000 people worldwide who lack pigment in their skin, hair and eyes. It is more common in sub-Saharan Africa and affects about one Tanzanian in 1,400. United Nations officials estimate about 75 albinos have been killed in the east African nation since 2000 and have voiced fears of rising attacks ahead of this year's election, as politicians seek good luck charms from witch doctors.

Albino body parts are highly valued in witchcraft and can fetch a high price. Superstition leads many to believe albino children are ghosts who bring bad luck. Some believe the limbs are more potent if the victims scream during amputation, according to a 2013 United Nations report.

A black flamingo is seen in a salt lake at the Akrotiri Environmental Centre on the southern coast of Cyprus April 8, 2015. The flamingo is thought to have a genetic condition known as melanism, which causes it to generate more of the pigment melanin, turning it dark rather than the usual pink colour.

Colour pigments are offered for sale in Medina, Rabat's old city September 24, 2014. UNESCO made Rabat a World Heritage Site two years ago and media and tour operators call it a "must-see destination." But it seems the tourist hordes have yet to find out. While visitors are getting squeezed through the better-known sites of Marrakesh and Fez, the old part of Rabat - with its beautiful Medina and Kasbah of the Udayas - remains an almost unspoiled oasis of calm. Smaller and more compact, its labyrinths of streets, passages and dead ends are a treasure trove of shapes and colours, of moments begging to be caught by the photographer's lens.

Pigment extracted from the cochineal insects are displayed at a Cochineal Campaign lab in Nopaltepec, state of Mexico September 30, 2014. In the shadow of the massive El Popo volcano, cactus growers in Mexico are helping to revive an ancient dying tradition with the help of a tiny bug that feeds off the country's prickly pears. The humble cochineal insect once occupied a proud place in pre-Hispanic culture as a natural dye for clothes and art. But over the years synthetic colours and the bug's parasitic nature saw it lose favour with local farmers. But amidst worldwide demand for the bug that has come from unlikely sources such as Starbucks and fashionistas, growers of the bug are cashing in. Picture taken September 30, 2014.

A visitor takes photos at University Museum of Contemporary Art (MUAC) in Mexico City October 1, 2014. The exhibition "Teoria del color" (in english "Theory of Color") is a sample of contemporary art about racism, that sarcastically exposes the social distribution based on the exclusion from the skin pigmentation. The exhibition curated by Mexican artists selected works from artists from Africa and America, mainly. The poster (L) reads, "Now, we are all black". REUTERS/Edgard Garrido (MEXICO - Tags: SOCIETY)
