PMI Chart

 This week for reading we had to complete a PMI chart. For the chart we had to use 3 sources of imformation and then complete the table with the positives the negatives and the interesting. Here it is.

PMI Chart

Topic:  Are icebergs harmful or helpful?

Source of Information	Plus	Minus	Interesting
the world's largest iceberg	- the vast quantities of dust riding aboard A68a could fertilize nearby ocean plankton. - sending planktons up the food chain to fish, penguins and seals.	- could crush animals.  - block off foraging routes for thousands of penguins and seals. - potentially disrupting the island's ecosystem for a decade or more - the island ecosystem could be seriously disrupted if the berg makes landfall.	- It may be on a collision course with a wildlife haven in the South Atlantic Ocean. - It’s large enough to hold the five boroughs of New York City five times over.
Icebergs are doing something cool.	Natural fertilizer for the ocean.  When they melt they release minerals like iron into the ocean.  Growth of microscopic marine plants known as phytoplankton. The new plant growth captures carbon, helping to reduce climate change.	No negative things in this text.	Scientists can see from satellites where an iceberg has passed.  They will see the recent growth of marine life.  The Iceberg  acts like a natural fertilizer.
Ice pirate	It will source 20 percent of the population of cape town for a year.  Will give water to people in need.  Will keep the taps from running dry.  Will be paid for.	- Severe drought in 2017 led to South African city Cape Town nearly running out of water. - The mission is expected to cost around $285 million.	- In the mid 1800s, Chilean breweries would tow small icebergs.
