Answer preview
From the graph, it is evident that the deforestation rate increases with the growth of the HDI and decreases with the reduction of HDI. In the 1980s, the graph indicates that an increase in the HDI increases the level of deforestation rate (JHA and Bawa. 2006). Compared to the 1990s graph, in the 1980s, the deforestation rate was high, which was mainly attributed to poor environmental sustainability policies. Also, some countries with higher HDI may have implemented policies that are not oriented in environmental conservation.
