Scientists around the world are facing a dilemma. A March for Science will be taking place in Washington DC on 22 April, with solidarity marches in more than 500 other locations around the world. Scientists in cities from London in the UK to Tokyo in Japan, Accra in Ghana and Hyderabad in India are all looking to defend the vital role that science plays in society.
The campaign – which calls for science to be robustly funded and publicly communicated as a “pillar of human freedom and prosperity” – is likely to be the largest ever mass demonstration by the scientific community. But every scientist who decides to march will know that, while they are taking part in a powerful movement to protect their discipline, they could also be helping to politicise a field that might be better off remaining as apolitical as possible.
