Interdisciplinarity is the bringing together of several disciplines in order to study a question of interest. Economics is a social science and hence intrinsically interdisciplinary: theorists & practitioners should, as scientists, acknowledge that social issues involve all the social sciences, especially political science and sociology. And the sub-disciplines of economic geography and economic history can be critical for a wider understanding of central economic issues such as inequality, underemployment and Brexit. Mitigation of climate change, in particular, involves engineering, economics, social psychology, politics and law.
