The Arctic is particularly vulnerable to climate change, but efforts to tackle it risk alienating the people who live there.

De-icing salts help us get around in winter, but they corrode cars, crack roads and contaminate rivers and lakes. Scientists are working to develop better options by imitating natural antifreezes.

A recent US study found tyre chemicals were polluting rivers and poisoning migratory salmon.

Millions of miles of fences crisscross the Earth's surface. They divide ecosystems and affect wild species in ways that often are harmful, but are virtually unstudied.

For every kilometre of road in Europe, you're likely to find one dead hedgehog.

Irish trade with the EU contributes an additional 34 tonnes of toxic nitrogen oxides to air in the UK each year.

Fish need to cross roads too. But the tunnels built to channel rivers under roads and railways can block their migrations.

City streets were built to accommodate cars, but the COVID-19 pandemic has scrambled our transport needs. Many cities are moving to make streets more people-friendly and less car-centric.

New research reveals how roads channel microplastics from car tires and brake pads to remote ocean habitats.

My research into Britain's birds found 77% of species varied in abundance around roads.
