Enriching the Sea to Death
A: List the major ideas, concepts or key points- point by point.
• Photosynthetic blooms increase the supply of organic matter to aquatic ecosystems, a process known as eutrophication.
•Pollution-driven eutrophication was not recognized as a serious threat to many larger lakes in Europe and North America until the 1950s and 1960s
•Difference underwater results from the precarious balance between oxygen supply and demand in aquatic ecosystems.
•Water circulates less readily than air and holds only five to 10 grams of oxygen per cubic meter at best.
•Although fish and a number of other aquatic animals have adapted to live the way, a small change can be fatal.
•More abundant the bloom, the heavier the fallout to the lower depth, bacteria that digest this dead plant matter consume oxygen.
•Oxygen rapidly becomes scarce below the surface. Animals that cannot escape to better-aerated zones will suffocate,
•Bacteria take over bottom water.
•Oxygen deprivation cuts a lethal swath through some 18,000 square kilometer.
B: Summarize the AUTHOR’s main point or idea- at LEAST 1-2 paragraphs
An excess of nutrients flowing from the land into the sea has created serious environmental problems in many coastal waters. Only recently have measures been taken to forestall the worst effects. The population has increased on the past year, and also their cravings. Farmers have been applying exponentially increasing amounts of fertilizer to their fields. This has made improved phosphorus removal from sewage. The amount of seaweed blooms increase the supply of organic matter to aquatic ecosystems. Although the marine-life has adapted to live under this circumstances, and small decrease in the oxygen can be fatal. And this is what the increase in the seaweed is doing. Oxygen rapidly becomes scarce below the surface. Animals that cannot escape to better-aerated zones will suffocate

If we could make a change, if the quantity of the seaweed that goes into the ocean, decrease, this would mean that we would have to go back to the way thing were. We would be using, and deposited our excrement in dry ground. I found this disgusting, and wasteful. But if we don’t do anything we are going to end up with no fish, food, and well we need food to be able to digest. It is funny, how things have changed. 40 years ago the ocean was thought to be immune to the combined forces of nutrient enrichment and oxygen depletion. But the was before the water was contaminated at big scale.
What?
Too much seaweed that’s in the ocean, it changing the oxygen in the ocean, affecting the living things in it.
Say’s who?
A professor of oceanography at the University of Rhode Island.
What if?
We could reduce the rate of seaweed that goes into the ocean. This would reduce the change in the oxygen that’s affecting the small animals.
What does it remains you of?
About the pH of the water, that’s becoming more acidic. That was affecting the marine-life, as well as this it’s affecting the marine-life. In both cases, the changed in the water it’s affecting the living things.
