Question

Drivers should not throw antifreezing solutions into the sea.

Fishermen should not throw used fishing gears/tackles and nets into the sea.

Factories should not throw waste oil into the sea.

People should not throw plastic bags and plastic bottles into the sea.

(Would you check the expressions above? If you have some more things that people can do to save the sea, would you list them?)

Answer 1

In the first sentence, it should be "antifreeze," not antifreezing.

Second sentence: "gear" is singular. So it should be fishing gear/tackles . . .

The others are correct.

People shouldn't throw any garbage into the sea. This includes the plastic loops that hold six-packs of soft drinks and beer. Boats should empty any waste products (including from toilets) into the sea.
