The U.S. carmaker Tesla’ new factory plan in Germany is facing protests. Tesla announced plans last November to build its first European car factory in Gruenheide, in the eastern state of Brandenburg.

Politicians, unions and industry groups have welcomed the move, saying it will bring jobs to the region, but environmental concerns drove hundreds of locals to the streets, according to Reuters.

Saturday’s protest came after a Brandenburg water association on Thursday warned against “extensive and serious problems with the drinking water supply and wastewater disposal” for the proposed factory.

Anne Bach, a 27-year-old environmental activist, said Tesla’s plans published earlier this month showed it would need more than 300 cubic meters of water per hour which would drain the area’s declining reserves.

Saturday’s protest highlighted the deforestation of around 300 hectares to build the factory and its impact on ecosystem.
