The activities of Mundus maris asbl and its partners to celebrate World Environment Day (5 June) and World Ocean Day 2022 (8 June) started already in May with raising awareness in two classes at the Colegio Bilingüe Báltico in the Veracruz Province, Mexico. The UN motto for this year ‘Revitalization: Collective Action for the Ocean’ is particularly stimulating and timely in the light of several major reports published in the last few months and painting a gloomy picture of greater negative impact of human action on the ocean than expected. Having said this, the research also shows that much worse can be prevented by determined collective action, e.g. weaning us faster from fossil fuels and delivering the deal in the World Trade Organization (WTO) to finally phase out harmful fisheries subsidies.
