The Secretariat of the Convention on Biological Diversity is pleased to announce the Biodiversity Day 2021 slogan: “We're part of the solution.” The slogan was chosen to be a continuation of the momentum generated last year under the over-arching theme, “Our solutions are in nature”, which served as a reminder that biodiversity remains the answer to several sustainable development challenges. From nature-based solutions to climate, health issues, food and water security, and sustainable livelihoods, biodiversity is the foundation upon which we can build back better.
