The diagrams illustrates the number of polar bears found in a survey of four locations at Western Hudson Bay in Canada in the year 1985 and 1995. In general, the numbers of polar bears have decreased drastically over the time span of just ten years. In contrast, there is a specific region which has gotten a slight increase in its bear population.
firstly, the total population of bears have been decreased significantly from 881 in 1985 to 575 over the ten-period timeline. However, despite the decline in the number of bear population, the proportions have still stayed quite stable in churchill north and cape totnam southeast contributing to about the half of the population of the animal. On the other hand, Cape Totnam north suffers major fell in the population from about quarter of the total population to approximately 8th of it. In contrast, only one area experience the slide increase of the numbers of polar bears but only of six.
In conclusion, not only the numbers of polar bears have decreased dramatically, but also the division of the population over certain areas also have changed over the total span of 10 years
