Nickel mining on Indonesia's remote Halmahera island is threatening food production for the Indigenous Sawai tribe. The mining pollutes the water, degrades the land and kills off fish stocks.

Nickel is a critical component for lithium-ion batteries used in renewable energy technology and EVs. Global demand has brought fundamental changes to people's lives here.

The mining site at Weda Bay Industrial Park has damaged coral reefs along the coastline. Many locals have been forced to sell their land due to financial pressure.

And things are likely to get worse. The mining site is set to grow threefold in the coming years, with international companies looking to invest.

"The nickel will eventually run out," said local legislator Sakir Ahmad. "Then we have to develop all the sites to improve people's quality of life. So, using the profit from nickel, there must be a bigger budget for the education sector. Children in our area must receive a better education."
