Synthesizing information is not simply stating a bunch of facts. Instead, synthesizing information requires you to look at the facts and identify trends or patterns you see (and sometimes, things you don't see). For example, average Canadian CO2 levels were presented in the lab for 1976, 1980, 1985, 1990, 1995, 2000, 2005, 2010, 2015, and 2020. These facts were then synthesized into a short paragraph: Canadian Co2 levels have been steadily increasing from 333.4 parts per million since 1976. In 2022, the concentration levels hit 419.7 (a 25% increase over 1976). 

Research and synthesize facts to answer the question: How has food insecurity changed in Canada since 2005? Write a short (3 or more sentences) paragraph.
