Australian scientists announced the discovery of the world's biggest dinosaur in the Damper Peninsula in north-western Australia. Measuring just under six feet in length, the track is believed to belong to a sauropod, a long-necked herbivore. The footprint was just one of twenty-one dinosaur tracks found, as well as rocks dating back 140 million years and evidence confirming the existence of stegosaurs in Australia.

The United Nations Environment Program is ramping up efforts to combat contamination of the world's seas and oceans from plastic pollution through its Clean Seas campaign. Statistics show that 80 percent of all litter in the oceans is from microplastics. Each year more than eight million metric tons of plastic end up in the oceans, endangering marine wildlife and costing over $8 billion in damages to marine ecosystems. A study by Greenpeace shows that more than five trillion plastic fragments weighing more than 250,000 tons are afloat at sea and have been ingested by marine life as deep as six miles.

In its recent report, Inheriting a Sustainable World: Atlas on Children's Health and the Environment, the World Health Organization reports that polluted environments kill 1.7 million children under the age of five each year. Air pollution alone results in 570,000 of these deaths and is also guilty of stunting brain development, reducing lung function, and increasing children's risk of heart disease, stroke, and cancer.

A massive effort to immunize 116 million children against polio was conducted by UN agencies across western and central Africa in late March 2017. Over 190,000 health workers went door to door to vaccinate every child under the age of five throughout the cities, towns, and villages of thirteen countries (Benin, Cameroon, Central African Republic, Chad, Cote d'Ivoire, Democratic Republic of Congo, Guinea, Liberia, Mali, Mauritania, Niger, Nigeria, and Sierra Leone). The campaign was launched after an outbreak in northeastern Nigeria in 2016.

Pakistani officials are pressuring Facebook to help investigate "blasphemous content" posted on the social network. Blasphemy is considered a highly sensitive and incendiary offense in Pakistan and in some cases carries the penalty of death. Officials encourage citizens to report anyone involved in posting such material online, even though what constitutes blasphemy is quite nebulous.
