Real Betis chief executive Ramon Alarcon accepts an environmental initiative called ‘The Greenest Game’ being held before their fixture with Manchester United in San Diego does not address the bigger impact of overseas pre-season tours.
Alarcon will be part of a delegation, including former United striker Andrew Cole, that will announce a partnership to clean up Mission Valley, an ecological preserve located along the San Diego River.
In addition, Betis will be handing out biodegradable bags at Wednesday's game with United at the Snapdragon Stadium to encourage fans to clean up their litter.
The players will drink from green reusable bottles to raise awareness about the problems facing the environment.
