This year’s World Environment Day theme, “Time for Nature”, reminds us that our lives, culture, society and economies are inextricably linked to a healthy planet where nature can thrive. Migratory species are an essential component of ‘biodiversity’ – the variety of life on Earth - and provide direct benefits, such as pest control, pollination and seed dispersal, as well as forming the basis of sustainable tourism and wildlife watching, which generate significant revenues and employment for millions of people around the world.
