A city plans to build a landfill which is near a river and farmland to manage growing waste. Which strategy best protects the ecosystem while supporting urban development?
Build the landfill with protective liners and fund community recycling programs.
A landfill near a river and farmland can pollute them through leachate, the liquid that seeps out of decomposing waste and carries harmful chemicals into the soil and water. A good plan must stop this pollution and also reduce the amount of waste reaching the landfill.
Protective liners at the base of the landfill prevent leachate from entering the groundwater, the river and the farmland. Community recycling programmes reduce the waste sent to the landfill. Together they protect the ecosystem while still letting the city manage its growing waste.
Incinerators near the river would release air pollutants and ash close to the water. Moving the landfill to a rural area without extra measures only shifts the same pollution elsewhere, and dumping waste directly into the river and farmland would cause severe contamination.
Hence, Build the landfill with protective liners and fund community recycling programs.
