Top 10 Most Peaceful Countries in the World – 2026 Rankings

THE CRA PERSPECTIVE • WORLD & SOCIETY The 10 Most Peaceful Countries in the World Where safety, stability and social harmony create a better environment for life. 2026 GLOBAL PEACE INDEX EDITION   Imagine living in a country where people feel secure walking through their neighbourhoods, institutions function reliably, communities coexist peacefully and international disagreements are less likely to turn into violence.

It allows children to grow up with confidence, businesses to invest, communities to prosper and individuals to pursue their ambitions without the constant fear of conflict. But peacefulness is not simply the absence of war. It also involves personal safety, political stability, low levels of violence, peaceful relations with neighbouring countries and a society in which people can trust the institutions around them.

How does Earth maintain a constant level of oxygen?



It doesn’t! The oxygen level of the planet has varied quite dramatically in the last 500 million years. It was 35 per cent during the Carboniferous period, around 300 million years ago; as the climate, cooled and land plants died off, oxygen fell to as low as 12 per cent by the beginning of the Triassic. Back then, the air at sea level would have felt thinner than at the top of the Alps today.


Burning fossil fuels has reduced oxygen levels very slightly – about 0.057 per cent over the last 30 years. Deforestation only has a small effect because when rainforest is cut down, other plants are usually grown in its place. But it’s marine phytoplankton (plant plankton), rather than trees, that produces about 75 per cent of atmospheric oxygen. Global warming will have a significant impact on phytoplankton, which is a much more serious threat to oxygen levels.

Rejected by KFC, Remembered by the World: The Jack Ma Story

THE CRA PERSPECTIVE • SUCCESS & LEADERSHIP Rejected by KFC, Remembered by the World: The Jack Ma Story How rejection, persistence, curiosity and an unconventional vision helped shape the journey behind Alibaba. RESILIENCE • ENTREPRENEURSHIP • POSSIBILITY Sometimes, the door that closes in your face becomes the beginning of a journey you never imagined. Imagine applying for a simple job, standing among 24 candidates, and discovering that you are the only person who has not been selected.

He has publicly recalled that 24 people applied for a KFC job in his city, 23 were accepted, and he was the one who was rejected. But the real story is not about a fast-food job. It is about wh...

Same Tree, Different Eyes: The Psychology of Perspective

THE CRA PERSPECTIVE • HUMAN PSYCHOLOGY Same Tree, Different Eyes Why we see the world differently—and how perspective shapes our decisions, relationships and lives. We do not always see things exactly as they are. We often see them through the lens of who we are. Imagine a large, beautiful tree standing beside a quiet road. Its branches stretch towards the sky, its leaves dance in the breeze, and its shade offers relief from the afternoon sun. A child might see a place to discover birds and nests. A carpenter might see the possibility of creating a table or a chair. A woodworker might think about timber. A businessperson might calculate its commercial value. An environmentalist might see biodiversity, ecological balance and the importance of conservation. The tree has not changed. Its physical presence remains the same. Yet the thoughts, emotions and possibilities it evokes are remarkably different. This simple observation ope...
