World Environment Day is celebrated annually on June 5th to raise awareness about environmental protection. The 2021 theme is ecosystem restoration, which is important for mitigating the ecological crisis and protecting biodiversity for future generations. Ecosystems provide valuable natural capital and services like carbon sinks. Their loss has contributed to increased greenhouse gas emissions and zoonotic diseases. The UN Decade on Ecosystem Restoration aims to protect and revive billions of hectares globally by 2030. Individuals can help by adopting sustainable lifestyles and supporting conservation efforts, while restoration activities involve revegetation and removing invasive species.
