Question

which waste management method is correctly matched to its potential harm to ecosystems?
recycling - release of hazardous waste due to combustion of recyclable material
ocean dumping - toxic ash as waste breaks down under sunlight
landfills - disposal of hazardous waste, such as e - waste, batteries, and some light bulbs
composting - thermal (heat) pollution in local waterways
incineration - production of methane, a greenhouse gas

Explanation:

Recycling is not about combustion - it's re - using materials. Ocean dumping's harm isn't about toxic ash breaking down under sunlight. Composting doesn't cause thermal pollution. Incineration doesn't produce methane mainly. Landfills can have hazardous waste like e - waste, batteries, and some light bulbs disposed of in them.

Answer:

landfills — disposal of hazardous waste, such as e - waste, batteries, and some light bulbs
