Members of Croydon Friends of the Earth toured mobile phone shops in the town centre on Saturday to raise awareness of their latest campaign.
As part of the 'Make it Better' campaign, shoppers and sellers were quizzed on whether they knew what lies behind some of the most popular mobile phones.
According to research from Friends of the Earth an essential component in mobile phones is tin, and mining the tin is killing coral and forests and also affecting the lives of communities overseas.
Rebecca Parnell of Friends of the Earth said: "We were delighted with the response from both shoppers and Croydon’s phone shop managers.
"They were really supportive of the campaign, and understood that customers are becoming increasingly concerned that people's homes and livelihoods are being destroyed just for their phones."
