killing the uk’s rivers? now that really is cheeky.

Meet siblings Tilda, 14, and Etta, 11.

They grew up swimming in the River Wye. Now they can't - it's turned brown and lifeless from factory farm pollution.

When they discovered Nando's buys chickens from farms poisoning their river, they wrote asking for help.

Nando's ignored them.

So they took matters into their own hands (watch the video!).

Factory farms are dumping toxic waste into rivers across Britain - and that's where Nando's gets their chicken. Time they proved their sustainability claims aren't just marketing.

"If we don't protect our rivers," says Tilda, "who will?"
