In more than 230 cities around the world - from Durban, South Africa to Washington DC and Sydney, Australia as well as Munich, Frankfurt and Cologne in Germany - marchers and demonstrators turned out for the second annual March for Science.
"There has not only been a concorted effort to undermine science but it is happening first time since Independence that absolutely no consultation is carried out with scientists on any government programmes", said D. Raghunandan of Delhi Science Forum and one of the organisers of the march.
Boston was another of the more than 200 cities around the globe that held rallies. Making sure that the education system does not impart ideas that contradict scientific evidence and to enact policies based on scientific evidence was also a part of their demands.
Washington's event began Saturday morning with teach-ins, expos and a rally that featured speakers and musical performances before participants planned to march to the US Capitol.

Lower Saucon resident MyLien Nguyen said she attended the rally because she supports science and wants the administration to support science. Education should not be limited to scientists, she said.
