The correct answer is D. Rainfall has been reduced in the tropical lands due to deforestation.
Deforestation is the permanent removal of trees to make room for something besides forest. This can include clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing.
When trees are cut down, they no longer absorb water from the soil and release it into the atmosphere through transpiration. This can lead to a decrease in rainfall in the surrounding area. Additionally, deforestation can also lead to an increase in soil erosion, which can further reduce the amount of water that is available for rainfall.
A study published in the journal Nature Climate Change found that deforestation in the Amazon rainforest is causing a significant decrease in rainfall in the region. The study found that for every 1% of forest that is lost, there is a 1% decrease in rainfall. This decrease in rainfall is having a negative impact on the region’s agriculture and water resources.
Another study, published in the journal Science, found that deforestation in the Congo Basin rainforest is also causing a decrease in rainfall. The study found that for every 1% of forest that is lost, there is a 0.5% decrease in rainfall. This decrease in rainfall is having a negative impact on the region’s agriculture and water resources.
Deforestation is a major problem that is having a significant impact on the environment. It is important to take steps to reduce deforestation and protect our forests.
Option A is incorrect because it states that tropical lands have been reduced by rainfall. This is not the case. Rainfall is not a factor that causes deforestation.
Option B is incorrect because it states that rainfall has been reduced and caused deforestation. This is also not the case. Deforestation is the cause of reduced rainfall, not the other way around.
Option C is incorrect because it states that reduced rainfall deforested. This is not a complete sentence and does not make sense.
Therefore, the correct answer is D. Rainfall has been reduced in the tropical lands due to deforestation.
