The United Nations is marking its 75th anniversary at a time when the world is experiencing dramatic changes and complex challenges, from the climate crisis to risks arising from new technologies, and most recently, the worst global health emergency of our time – COVID-19.

Through these challenging times, the United Nations’ dedication to action on issues confronting humanity remains steadfast. UN75 offers an opportunity to reflect on milestones achieved through multilateral cooperation and partnerships, and to discuss as a human family our priorities now and going forward.

World Humanitarian Day (WHD) is celebrated every year on 19 August to pay tribute to aid workers who risk their lives in humanitarian service, and to rally support for people affected by crises around the world.

Worldwide consumption and production — a driving force of the global economy — rest on the use of the natural environment and resources in a way that continues to have destructive impacts on the planet. Economic and social progress over the last century have been accompanied by environmental degradation that is endangering the very systems on which our future development and our very survival depend.

Inclusive and sustainable industrialization, together with innovation and infrastructure, can unleash dynamic and competitive economic forces that generate employment and income and play a key role in introducing and promoting new technologies, facilitating international trade and enabling the efficient use of resources.

The sustainable development agenda cannot succeed without partnerships with governments, civil society, scientists, academia and the private sector. These inclusive partnerships, built upon a shared vision and shared goals and values that place people at the center, are needed at the global, regional, national and local level.

We depend on our environment for the food we eat, the air we breathe, the water we drink and the climate that makes our planet habitable. For example, each year marine plants produce more than half of our atmosphere's oxygen, and a mature tree cleans our air, absorbing 22 kilos of carbon dioxide and releasing oxygen in exchange. Despite all the benefits we receive from nature, we’re not always good stewards of our environmental gifts; to care for ourselves we must care for nature. World Environment Day is the most renowned day for environmental action.
