Should oil be poured down the kitchen sink?

Improper oil disposal can also have a detrimental effect on the environment. Sewage systems that overflow due to blockages can leak contaminants into local waterways, harming aquatic life and polluting drinking water supplies.

When oil makes its way into natural water bodies, it can coat the feathers or fur of wildlife, affecting their insulation and buoyancy. This can have fatal consequences for animals exposed to polluted water.
