Making our mark on World Population Day

On World Population Day 2018, Population Matters took to the streets of London with a truck-mounted mobile digital display of the “population clock” – global population growth live. People reacted with surprise, disbelief and shock. Watch the video, see the reactions – and see the numbers tick up and up.

The Population Clock

We took the van to many London locations, from Trafalgar Square to the London School of Economics to Parliament and Oxford Street, one of the busiest shopping streets in the world. We also took it to the London HQ of Friends of the Earth, to remind them of the importance of tackling population growth to protect the environment.

The van also joined Population Matters’ London Group as they held a leafleting session near the National Gallery in London, with the help of Anthropocene campaign mascot, Big Foot.

Take action

On World Population Day, we joined population organisations from across the world in asking for governments to respond to the Second World Scientists’ Warning to Humanity. This statement, now signed by more than 20,000 scientists, demands action to avert environmental catastrophe – including on population. Support the warning and take action here.
