▶ Your Answer :
The graph shows information about species extinctions in tropical
forests and the chart informs the reason why plants threatened.
In the first graph, there is
a steady increase between 2000 and 2060. It is amazing that the figure is
predicted to rise about 10 times until 2060, when it will hit a peak at 50,000.
Although it will be decreasing less steeply, to 28,000 per million in the year
2100, it is still much higher than now.
What does catalyze this phenomenon? The chart takes a close look at
the impact of different types of activity on plant survival. Clearly, over
three-quarters of extinctions are caused by human activities, and more than
half of this is related in some way to farming.
Natural events, on the other hand, have much less effect on the
lives of plants. Natural disasters, such as tropical storms, account for
7percent of extinctions, while other natural influences cause a further 11.7
percent.
To sum up, extinctions in tropical regions will get much worse
before they eventually fall. Meanwhile, human beings are likely to be
responsible for the greater part of these. |
