We live in a time of unprecedented population growth. People born 60 years ago have seen the population of the world triple. In the UK, in the past 100 years, the population has grown by over 20 million. But why is our population growing? What are the consequences if it doesn’t stop? And is population growth necessarily a bad thing? Our reporter Benjamin Zand has been finding out.

The space race between the capitalist US and communist USSR saw decades of competition to push the boundaries of what mankind could achieve in space, all in the name of ideological superiority.
Now, a new space race is underway, but instead of a clash of cultures, this is a clash of egos – between two billionaires who made their fortune on the internet.
But Amazon’s Jeff Bezos and Tesla’s Elon Musk don’t simply want to get us back to space – they want us to stay there.

There are few human activities that have changed the world’s landscapes and environment more than farming. Fields of crops and pastures for animals occupy an extraordinary 40% of available global land. But the way we grow food on these vast swathes of land is putting increasing pressure on nature.
Growing demand for food has polluted much of the world’s water, soil and air with excess fertilisers and chemical sprays, which are remarkably inefficient. Up to 98% of a crop spray won’t stay on the plant but will instead bounce straight off, accumulating in the soil and eventually running off into waterways. At the same time, conversion of land from wild spaces to farming is driving biodiversity loss, as wild plants and animals have less space to live in.
Is it possible to transform the way we farm so that agriculture doesn’t compromise the natural environment? Because of the sheer scale of the world’s agriculture, it seems like a gargantuan task. But farmers and researchers are already developing the tools that will be needed to make it happen. Technology, used wisely, is one of them.
Many new innovations have the potential to redesign global food systems to make them sustainable. Some of them come from unexpected quarters. Bees can be surprisingly efficient and accurate crop sprayers. Clever chemistry can help get more pesticide to stay on target, drastically reducing pollution. Meanwhile, some types of indoor agriculture can produce more food in a fraction of the space used by conventional farming, leaving more space for nature outdoors.
Creating new and sustainable food systems that can support the world’s population is going to mean rethinking the fundamentals of farming, from the resources used, to where it happens and its basic relationship with nature.

Migrant rescue charity SOS Méditerranée has resumed operations off the coast of Libya with a new ship, after the last one was forced to stop its work by European governments.
Its new vessel, the Ocean Viking, is flying the Norwegian flag.
The crew of 31 includes nine health workers from the charity’s partners, Medecins Sans Frontières (MSF).
SOS Méditerranée suspended operations by its previous vessel, the Aquarius, after it was denied entry to Italy.
Thousands of migrants attempt to cross the Mediterranean to Europe every year, and Libya is a key departure point. Those who make the journey often travel in poorly maintained and overcrowded vessels, and many have died.
But since mid-2017, the number of migrant journeys has declined dramatically. The decline is largely due to efforts by Italy and other EU countries to encourage Libya to stop migrants from crossing the Mediterranean – a policy condemned by human rights organisations.

Hundreds of firefighters have spent the day battling wildfires in a forested, mountainous area of central Portugal.
Eight firefighters and 12 civilians have been injured in the Castelo Branco region, according to the interior ministry.
One badly burned civilian was evacuated by helicopter to the capital Lisbon.
Helicopters and tanker planes have been used to douse three major blazes in the region, with two now said to have been brought under control.
The biggest operation – involving 800 firefighters, 245 vehicles including bulldozers, and 13 planes and helicopters – is tackling a fire in the municipality of Vila de Rei.

‘Everyone is welcome. Everyone is needed’: Greta Thunberg photographed in her home city, Stockholm, March 2019. Photograph: Michael Campanella/The Guardian
Greta Thunberg. This time last year she was unimaginable. Then, pretty much from nowhere, there she was: small and slight, a girl just turned 16, the way-too-young odd person out on a panel of adults sitting in front of the world’s economic powers at Davos last January. Unshowy and serious, careful, firm, she said it. Our house is on fire.
The ancient Greeks had a word for this: parrhesiastes. It means a person who speaks truth to power: you should not be behaving in this way. Don’t. More specifically it suggests someone in whom directness of expression and access to truth coincide; and it means someone of very little power who’s risking everything – because they can’t not, there’s no option – to speak ethical truth to powers so entrenched that they’re close to tyrannical, because telling this truth is about moral law. “Some people, some companies, some decision-makers in particular know exactly what priceless values they have been sacrificing to continue to make unimaginable amounts of money, and I think many of you here today,” she said to the World Economic Forum conference, “belong to that group of people.”
Thunberg is Swedish; she was born in 2003 and lives in Stockholm with her younger sister Beata, her mother, a singer, and her father, an actor. There’s a picture of the family somewhere online taken when she was much younger; her mother and father are smiling broad old-fashioned smiles at the camera – doing what you do when you have your photo taken. Both the children, only waist- and knee-high, regard the lens with utter seriousness and inquiry. At eight years old, Greta Thunberg heard about climate change. She wondered why no one was doing anything to stop it. At 11 she stopped speaking, in protest; now she sees that “selective mutism” as the first step to understanding the power and necessity of speaking at all.
