Question 3

To answer this, we refer to environmental research: the estimated plastic debris from rivers to oceans yearly is 1 to 2 million tons. So option D matches this.

Research on ocean garbage patches shows that over 90% of objects are microplastics < 0.5 cm. So option D is correct.

Current studies show the garbage patch is growing rapidly due to ongoing plastic pollution. So option D is correct.

Answer:

D. 1 to 2 million tons
