A breakdown of the number of extinctions of plant and animal species in tropical forest from 2000 to 2100 as a projected year, a 10 - decade period is presented in the line graph and is measured by million, while the pie chart describes the proportion of plant life threatened extinction, categorized two causes, natural events and human impact. Overall, after a peak, the extinction of both species is forecast to decrease dramatically. In any case, the main problem of plant extinction is caused by human threat.

To begin, standing at approximately 5000 extinctions in 2000, the level of extinction is predicted to increase dramatically, peak at ten times of the period. This condition will become the worse condition over the question period, but this, then, will be estimated that a gradual decline of extinction level is predicted over the following 4 - decades period.

Next, It is clear that human impact is number-one causes of threats to plant life rather than natural events with 81% and 18,7% respectively. There are three major causes factors why the threats to plant life are due to development, harvesting, and agriculture; with the percentage over one in ten percent. By contrast, natural events, the number of plant life treated is only caused by natural disaster (7 percent) and other natural events (11,7 percent).
