The correct answer is D. Afforestation.
Afforestation is the process of converting non-forested land into forested land. It is often done to increase the amount of timber available, to provide habitat for wildlife, or to improve water quality.
Aforestation is different from reforestation, which is the process of replanting a forest that has been cleared. Afforestation can be done on any type of land, while reforestation is typically done on land that was previously forested.
Aforestation can be a controversial issue, as it can lead to the loss of natural habitats and the displacement of wildlife. However, it can also have positive environmental benefits, such as reducing soil erosion and improving air quality.
The other options are incorrect because they are not the correct spelling of the word “afforestation.”
