Answer
Correct option: D.
All of the above.
Deforestation is the cutting down of trees of the forest.
Due to this, the number of trees that can consume $CO_2$ and give out oxygen through photosynthesis, decreases.
Thus, there is an increase in atmospheric $CO_2$ levels.
As the $CO_2$ level increases, the greenhouse effect starts.
In this, $CO_2$ and other greenhouse gases, trap the heat of the sunlight and do not let it go.
This raises the temperature of the Earth causing global warming.
The roots of the trees hold the soil particles. Therefore, without trees, the topsoil gets washed away by water and wind and causes soil erosion.
