Answer:
by developing more efficient methods of mining coal
Explanation:
Coal is a combustible black or brownish black sedimentary rock. Coal is produced by the dead plant matter. It is a fossil fuel that is used for generating electricity in the thermal power plants, used as cooking fuel, and fuel in automobiles. The burning of the coal results in the liberation of carbon dioxide, sulphur dioxide and carbon monoxide gases in the environment. These gases are responsible for causing the air pollution.
Developing more efficient methods of mining coal is not a conservation tactic related to coal consumption because the more the efficient mining will promote the excavation of the coal, which will further contribute to its extensive consumption and air pollution.

Answer:
1. As the cell size increases, the ratio of surface area to volume DECREASES
2. It depends on the unit of the ratio 6:1. If it is in cm−1, then it means that it is similar to a cell of size 1 cm^3, which is normally too big to get materials from the surface
.
3. A Small cell has a large surface area/volume ratio and therefore can exchange molecules with it's external environment rapidly. So, Here cell with ratio 6:1 is smaller and have ability to better transportation across it's membrane as compared to other cell with ratio 3:1
HOPE THIS HELPS!!!
