World Environment Day is celebrated annually on 5 June and is the United Nations' principal vehicle for encouraging awareness and action for the protection of the environment. First held in 1974, it has been a platform for raising awareness on environmental issues such as marine pollution, human overpopulation, global warming, sustainable consumption, and wildlife crime. World Environment Day is a global platform for public outreach, with participation from over 143 countries annually. Each year, the program has provided a theme and forum for businesses, non-government organizations, communities, governments, and celebrities to advocate environmental causes.

5th of June - International Day for the Fight against Illegal, Unreported and Unregulated Fishing

Illegal, unreported, and unregulated Fishing is an issue around the world. Fishing industry observers believe IUU occurs in most fisheries and accounts for up to 30% of total catches in some important fisheries.

The term “IUU fishing” refers to fishing and related activities that operate outside the law and undermine sustainable fisheries.

IUU fishing includes many types of illicit activities, for example, fishing without a license or authorization, not reporting or misreporting catches, fishing in prohibited areas and catching or selling prohibited species, or fishing in areas not covered by a regulatory framework, IUU fishing takes place whenever fishing vessels do not operate in line with the requirements established by national, regional, and international regulatory schemes and management systems.
