Heathrow Expansion will mean river corridors dating back to the last Ice Age will be shortened and severely impacted beneath the new runway and taxiways. The only remaining re-routed waterway will be (by necessity) disconnected from landfill-contaminated groundwater and netted.

While we make the most of the sunny weather, sadly the #heatwave is not ok for UK nature and wildlife: rivers get overheated and flows depleted, pollution even worse than usual. Don’t be tempted to swim where there could be hidden dangers including underwater hazards and pollution.
