The human toll of the disastrous release of sludge from a huge impoundment storing the waste product of aluminium production in Hungary is shocking and our thoughts are with the communities so grievously affected. As frantic efforts continue to contain the impact of this toxic tide, the implications of the wider impact of the disaster are starting to become apparent. Already two rivers have been affected and a few miles downstream they join the Danube. This incident has the potential to wreak damage far beyond Hungary including the fragile natural environment of the Danube Delta.
We are supporting the work of BirdLife colleagues in Romania who are campaigning for a better future for the Danube Delta - and as we hear from our friends and colleagues in country's affected now or at risk from this massive pollution incident I'll bring them to you.
