For Our Future,” the country's national campaign tackles the dual crises of climate change and ecosystem degradation. This initiative drives home the critical message that nature is not optional, but the centre to building climate resilience and securing our collective future.
Message From UN Secretary-General:
"This World Environment Day, warning signals are everywhere. The past 11 years have been the 11 hottest on record. And the damage goes far beyond rising temperatures, from polluted air to degraded land, collapsing ecosystems, and vanishing biodiversity," said Antonio Guterres ahead of World Environment Day.
"The world is heading for a temporary overshoot above 1.5 degrees. Every fraction of a degree brings greater harm – especially to the most vulnerable. Our task is to make that overshoot as small, as short, and as safe as possible – and rapidly bring temperatures back down."
