Thanks for the suggestion, Mitchell, and welcome to the EA Forum!
Now I use words to introduce the data, and only afterwards provide the prefixes in parentheses:
The plastic emitted to the ocean in 2010 was 8 million tonnes according to OWID (PEO = 8 Mt).
The world population in 2010 was 6.92 billion according to The World Bank (WP = 6.92 G).
Marine plastic debris kills up to 1 million seabirds and 100 thounsand sea mammals each year according to the United Nations (SB = 1 M, and SM = 100 k).
The catch of wild fish is 0.97 to 2.7 trillion/​year according to fishcount.org (WFL = 0.97 T/​year to WFH = 2.7 T/​year).
In the calculations, I also clarify what is the meaning of the prefix I introduce there:
Seabirds killed by plastic marine pollution in 2010, per capita (DSBpC): PEOpC /​ PEOpDSB = 1.16 /​ (8 k) = 145 μ (145 seabirds killed per million people).
Sea mammals killed by plastic marine pollution in 2010, per capita (DSMpC): PEOpC /​ PEOpDSM = 1.16 /​ (80 k) = 14.5 μ (14.5 sea mammals killed per million people).
I agree with you that 10^x notation is more well known, so you do have a point! On the other hand, I wonder whether using prefixes could be useful for people to get familiar with more notations.
