Air pollution in Kenya was studied to see how economic growth affects environmental degradation. The researchers looked at carbon emissions and deforestation from 1990 to 2018. They found that as income per person increases, environmental quality first worsens, then improves. This supports the idea that economic growth can help the environment. The study showed that as GDP goes up, forest cover goes down, but CO2 emissions decrease. This suggests that economic growth can be good for the environment in Kenya.
