Samsung has admitted to using tin sourced from unregulated mining on Bangka Island in Indonesian in the manufacture of its Smartphones.
The mining puts coral and sea life under threat. Silt from tin mining kills seagrass which is eaten by turtles. And it drives away fish, damaging fishermen's livelihoods.
Soil has become acidic after the destruction of forests for tin mining and, as a result, farmers struggle to grow crops.
And according to police figures in 2011, an average of one miner a week died in mining related accident. This is due to poor safety measures.
All smartphones and tablets manufactured by Samsung contain between 1g and 1.3g of tin-rich solder. Nearly half of all mined tin is turned into solder for the electronics industry and roughly a third of the world's tin is from Bangka Island and the smaller Belitung Island.
According to the International Business Times, Samsung confirmed in an email to Friends of the Earth that it sources tin from Bangka island.
Samsung said in the email that it is "undertaking a thorough investigation of our supply chain in the region to better understand what is happening, and what part we play."
"While we do not have a direct relationship with tin suppliers from Bangka Island, we do know that some of the tin that we use for manufacturing our products does originate from this area, and as a responsible business we are contacting suppliers, industry bodies and governments…to find solutions."
