In our so-called advanced world of shopping malls and online stores packed to the brim with mass-produced "stuff" manufactured in power-guzzling, environment-polluting factories for those with the wealth to buy them, has consumerism spiralled out of control? When did the things we enjoy become things we buy rather than make?

The story of the Prime Meridian, an invisible line that silently choreographs the dance of time and space across the globe, is a tale of science, power, and intrigue. But standing with one foot in each hemisphere, I wondered whether this arbitrary line of imaginary division has a greater significance in our increasingly divided real world.

For nearly half a century, the Lost Violin of Kraków lay hidden in pieces, scattered throughout the house abandoned by victims of the Holocaust, until a master craftsman meticulously brought it back to life in their honour.

The Nazis murdered an estimated 1.1 million people in Auschwitz, most within the first few hours of arrival. What intense confusion, fear, and unimaginable brutality must they have experienced on their way to the gas chambers?

Are there words adequate to describe the emotion of passing through the gates of Auschwitz? Can a photograph truly do justice to the memory of those who met their dreadful end in the gas chambers at the end of the railway tracks? Those were my thoughts as I entered the infamous camp, which left such an indelible stain on 20th-century history.

For centuries, millennia even, people have gathered around a single focal point to share stories, sing, chant, make music and celebrate their communities. And yet, as the wheels of time have turned, these ancient practices have faded from memory as digital screens have become our new focal point.

As the boundaries between the virtual and real worlds continue to blur, how can the search for adventure help us maintain genuine connections and experiences in life.

Can a moment in time ever be recreated? I once thought so, but after trying to duplicate this photograph for weeks, I realised the futility of living in the past.

In 2013 a bunch of "scruffy skateboarders" challenged the might of the cultural elite of London. At first, few took much notice, but over the next 18 months, the skateboarders unleashed the power of local support with dramatic effect.

For nearly 200 years, Elmina Castle was one of the most prominent staging posts of the transatlantic slave trade. Today it stands as a reminder of humanity's inhumanity of the past. Or does it?

Despite being one of the most essential minerals on our planet, vital for maintaining human life, how many of us have ever considered where the salt we use every day comes from?

Mustafa is one of the poorest people I have ever met; he is always one of the most generous. His simple act of kindness led me to question what generosity actually means.

Believe it or not, I came very close to leaving Toronto without photographing Niagara Falls. The weather forecast was for heavy rain, and I would need to go at a crazy hour to reach the falls in time for sunrise. But a break in the storm allowed me to experience a moment which will stay with me forever.

Ours is a complicated world, so much so that sometimes we see complication even where it doesn't exist. But it was a chance encounter with a fisherman in Madagascar which left me wondering what solutions might be hiding in plain sight if we open our eyes to them.

This photograph, captured in 2013, will always be special to me. It was the first of my photographs to receive a thousand likes on social media, but more than that, it taught me how powerful a photograph could be.

How many stories could the crumbling walls of the old prison in Port Louis tell? Few would be surprised if they were stories of regret and despair for misdeeds which led to incarceration. More curious is the relief some prisoners must have felt as they entered the prison for the first time. Theirs are the largely untold stories of the willing prisoners who chose prison as an escape from the hardships of the plantations.

Cut off from the outside world, the inhabitants of this village with no name, located deep in the forest of Madagascar, have learned to become almost entirely self-sufficient. With no running water or electricity, everything in the village had to be done by hand. Are there lessons we can learn from their experiences?

Money and sport have always been uncomfortable teammates, but in the end, it has always felt like sport came first. But this World Cup feels different. Does the 2022 World Cup mark the moment when money takes the lead and sport is left to follow after?

Do you remember photographs? I mean real photographs — the kind you hold in your hand, not view on your phone. For those who are too young to remember (or those of you who are old enough but want to enjoy a walk down memory lane), let me share with you what is was like to capture moments on film rather than on a sensor.

At the age of 16, Janet Devlin became an overnight star. By the age of 20, she was an alcoholic. To her adoring fans, the singer from Northern Ireland had the world at her feet, but away from the public eye, her mental health was spiralling out of control.
