Best option to make different disciplines work together in tackling environmental health problems (multiple choice) 1 - The EU has to set up interdisciplinary workgroups on different topics. 2 - The EU has to oblige participants in EU-projects to join the HENVINET portal and add results of their project to the portal. 3 - We have to organise international soccer matches between toxicologists and epidemiologists. 4 - The creation of glossaries (perhaps through a wiki function) for scientific terms and policy terms. 5 - Continuous professional education needs to include obligatory courses of other disciplines. 6 - I have a great idea myself.
