(520 lm) divided by (13 lm/W)
= (520 lm) times (W/13lm)
= (520/13) (lm · W / lm)
= 40 W
Hello!
The removal of vegetation causes the desertification and erosion of soil. The roots of the plants that are inside the soil create a sort of net that prevents the material to be dragged by the water from the rain. They also absorb any excess water that can weaken the soil structure. If vegetation is removed from the soil, the nutrients can be dragged by water currents and slowly the desertification will occur.
Have a nice day!
