What are four ways that humans harm sea grass? explain in detail.

Pollution. We threw our cans and plastics in the sea and the animals in the sea eat or suffocate on/in/with these objects.

Pollution; waste and discharge falls into the water, polluting the sea grass. It reduces the amount of sunlight and the plant might die.

Poor land management; trees lead to the erosion of dirt, making the soil cloud up the water, not giving the sea grass sunlight.

Careless behavior; from people stepping onto the sea grass, to other items falling and smothering the sea grass.
