Answer to Question 1

Excess nutrients, such as fertilizer runoff, can stimulate the growth of some species to the detriment of others, destroying the natural balance of an ocean area. Huge blooms of phytoplankton can choke the gills of some animals and even deplete oxygen in ocean water.

Answer to Question 2

Runoff and discharges from land, and airborne emissions from land, are the largest sources of marine pollution. Examples of ways to reduce this pollution include limiting the emission of carbon dioxide that warms the climate and acidifies the ocean, reducing and recycling plastic waste, reducing the amount of agricultural fertilizer that is able to run off into rivers, and reducing urban and industrial releases into bays.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
