Question

the oceans dead zones
the good news is that dead zones do not have to stay dead forever. scientists say people can do two things to make oceans healthy again. the first is to decrease the amount of nutrients used to grow plants on farms and in gardens. these fertilizers are the main cause of dead zones in the ocean. the second is to grow plants that will keep the soil along riverbanks and oceans from flowing into the water during heavy rains. this will keep the dangerous plant food out of oceans and lessen the formation of dead zones.
how can people help improve the oxygen levels in dead zones?
select one:
○farmers can plant algae along the banks of rivers and oceans.
○people can stop fishing in the ocean.
○farmers can use less plant food.
○people can grow their own fruits and vegetables.

Explanation:

The text states that fertilizers (plant food) are the main cause of dead zones. Decreasing their use (farmers using less plant food) aligns with the first suggested action (decrease nutrient amount). Planting algae isn't mentioned. Stopping fishing isn't related to the causes. Growing own fruits/vegetables doesn't directly address the fertilizer - dead zone link.

Answer:

Farmers can use less plant food.
