Walking and cycling produce no tailpipe emissions. This reduces the amount of CO2, nitrogen oxides, and particulate matter entering the atmosphere.
The most significant advantage of active transport is the ability to accumulate substances within a cell, even when the concentration inside is already higher than outside. This is vital for nutrition.
In epithelial tissues (e.g., gut lining, kidney tubules), active transport allows for directional movement of molecules.
