The given line graph depicts the number of three distinct wildlife species populations between 2017 and 2022.
Overall, while the number of bear populations witnessed an upward trend, the figure for Dolphins and whales saw the opposite. Additionally, despite the bear inhabitants having the lowest number in 2017, it took over the other species and became the highest.
In 2017, the figure for bear residents was about 10 million. However, it started to increase gradually until 2021, approximately 40% to 50% annually. In the year 0f 2022, the number of bear denizens recorded a significant rise and reached its peak of over 180 million.
In contrast, the quantity of dolphin populations saw a dramatic decrease. In 2017, dolphin numbers were at the top – around 150 million. Nevertheless, the figure for Dolphin dropped wildly in the next two years. Unstoppably, it kept going down slowly, roughly 5 to 20 million each year, until hit its bottom in 2022 at 0 million. On the other hand, the number of whales fluctuated erratically in the first two years, particularly between 2019 and 2020, around 40 million. Afterwards, in the last three years, it variated slightly by about 18-20 million yearly.
