The line chart provides information about the populations of three wild animal species (whales, bears, and dolphins) in North Africa from 2017 to 2022.
Overall, the numbers for dolphins and whales both showed a downward trend, while the number of bears increased significantly. Among the three, bears experienced the most notable growth over the period.
Starting at nearly 160 in 2017, the population of dolphins was the highest, approximately twice and eight times higher than that of bears and whales, which had populations of 80 and around 20, respectively. However, in the following years, the population of dolphins dropped significantly to 80 in 2018, and then reached its lowest point on the line chart, falling to under 10 by 2022.
In contrast, despite starting with the lowest number, the bear population boomed. By 2018, the number of bears equaled that of whales and dolphins, but it quickly overtook the other two species, becoming the highest figure. From 2019 onwards, the bear population gradually increased, reaching a peak of 180 in 2022.
Finally, while the number of whales showed significant fluctuations, ranging between 80 and 100, it remained the second-highest figure throughout the given period.
