England's natural environment is in decline and its deterioration is harming the economy, an independent advisory group has told the government.
The Natural Capital Committee says pressures will rise with population growth and has called for a 25-year investment plan.
Its report said measures like investing in improved air quality and greener cities would bring economic benefits.
Defra said it had set "long-term goals" to halt "decades of decline".
