What is likely to happen in the future to that ecosystem?

 As mentioned earlier, human impact plays a large role in the rainforest ecosystem. The two major human impacts are slash-and-burn agriculture and logging. If the decree, passed in 2010, manages to prevent all illegal logging and poaching from taking place, it will eliminate one of the major problems. Nonetheless, if slash-and-burn agriculture continues to occur, the forest will still continue shrinking in size, though at a slower rate. Even worse, if the decree is ignored, the rainforest will continue to decline and shrink in size. In this case, the rainforest will continue to thin until there is almost no vegetation left to be considered a tropical rainforest. This prospect of the future is a horrifying possibility. In order to maintain the rainforest, we must come up with ways to inhibit human destruction.

According to this graph, the tropical rainforest of Madagascar is less than a quarter of its original size and the annual deforestation rate is 2,000 square kilometers per year. If this continues and a set rate, in approximately five years the tropical rainforest will no longer exist. The evidence on this graph suggest that the future of the forest is gloomy.
