Answer:
Ocean desalination, Using nuclear fusion as an energy source and using stem cell technology to cure disease.
Explanation:
Ocean desalination is the major problem that occurs due to removing of nutrients that is present in the ocean water because of human activities. These nutrients are essential for the marine animals so for solving this problem, we should use other alternative energy resources in order to reduce ocean desalination. Using nuclear fusion as an energy source is a good idea but it can't be implemented on the earth because it requires 100 million degrees Celsius which is impossible to generate. Using stem cell technology to cure disease is a great idea which can cure many diseases in the human body. This available technology is used by replacing damaged cells with the healthy cells.

Endoplasmic reticulum is responsible
Answer:
Deforestation negatively impacts the <u>carbon cycle</u> as <u>trees</u> play an important role in <u>balancing the amount of carbon in the atmosphere</u>.
Explanation:
Deforestation is one of the most damaging activities to the environment due to different reasons but mainly because it releases important amounts of carbon dioxide to the atmosphere due to the logging and burning of forests and also leads to the reduction of fauna populations because of habitat destruction.
In this case, cutting white and red pines and then setting a pine acreage on fire disrupts the carbon cycle because:
a) [As stated above] <u>Trees play an important role in balancing the amount of carbon dioxide (CO2) in the atmosphere</u><u> as there is less photosynthesis carried out by plants - important part of the carbon cycle.</u>
b) <u>When </u><u>trees (wood) are burned, the carbon that was formerly stored is released into the atmosphere as CO2,</u> leading to another disruption in the carbon cycle.
It is definitely not a primary source: this would be a book itself.
Now, is it a tertiary source? I don't think so: the author of the review should have read the book and should only be referring to this book in the review.
I think it's a secondary source.
