Explanations:Forest cover is a critical aspect of a state's geography and environmental health. It refers to the total area covered by forests within a given region. The percentage of forest cover can vary significantly between states due to a variety of factors, including topography, climate, and human activities such as industrialization and urbanization.
Punjab, being a predominantly agricultural and industrial state, has a lower forest cover compared to other states. The state's flat topography and extensive agricultural activities have contributed to the reduction of forested areas. Additionally, the industrialization in Punjab has further reduced the forest cover as land is often cleared for industrial and urban development.
On the other hand, states like Bihar and Sikkim have higher forest covers due to their varied topography and conservation efforts. Bihar, with its diverse landscape including hills and rivers, has several forested areas and national parks. Sikkim, being a mountainous state, has dense forests and a high level of biodiversity, which contributes to a higher percentage of forest cover.
It is important to note that the forest cover can also be influenced by government policies and conservation efforts. States that prioritize forest conservation and reforestation efforts tend to have a higher forest cover. In the context of the given options, Punjab has the least area under forest cover due to its geographical and industrial characteristics.
