Act Now -The United Nations Campaign for Individual Action -Malta 2021.

Over the years, our planet Earth has been subjected to severe depletion of natural resources including, among others, fossil fuels and deforestation coupled with a sharp increase of carbon dioxide in the atmosphere causing extensive climate change.
No doubt people are the primary cause of climate change. Temperatures are rising, glaciers are melting, sea levels are rising, forests are dying and animal species are being driven out of their natural habitats.
A report published by the National Oceanic and Atmospheric Administration and NASA in 2019 confirms that the past decade was the hottest since record-keeping began some 140 years ago.
In December 2018, the United Nations introduced the ACT NOW Climate Action campaign so as to promote a sustainable lifestyle. This campaign aims to inspire and educate people around the world in a battle to confront the climate crisis by taking individual action and reducing human impact on the environment.

This Malta stamp issue supports this campaign by encapsulating three separate symbols, one on each stamp; Reduce, Reuse and Recycle, also called the 3 Rs.
Each day every individual makes a number of decisions and actions. If everyone were to implement small changes in their day-to-day lives by simply Reducing waste, Reusing things, and Recycling altogether, then we could drastically reduce the impact on the environment.
