The line graph indicates the number of population change in three variety of wild animals, including bears, dolphins, and whales, measured in milions, in North America between 2017 and 2022.
From an overall respective, the figure for bear populations rose sharply, whereas there was a dip trend in dolphin populations. Additionally, there was a fluctation in the number of whales from 2017 to 2022.
Starting at bear populations, the figure for bears in North America stood at only approximately 10 milions, which is the lowest number in the chart. However, there was a dramatic climb in bear populations and reaching a peak of 180 milions in 2022.
In contrast, dolphin populations were highest in 2017, at 150 milions in the wild. From 2017 to 2019, this figure delined rapidly to 30 milions. In the following three years, this figure again decreased gradually and reaching the bottom of 1 milions in 2022. Finally, whale populations experienced a dramatic fluctation from 80 milions to 100 milions throughout the period.
