Answer:
As your level of activity increases, your breathing rate increases to bring more air (oxygen) into your lungs so that your lungs can pump more oxygen into your blood and out to your muscles.
Soil pollution: Because of the depletion of microbe biodiversity in soils, crop production now necessitates the use of fertilizers and pesticides. The value of good soils must be encouraged and understood.
Habitat loss: Food processing necessitates the use of both water and energy. If nothing is done, the global food system may lead to rapid and widespread biodiversity loss. Agriculture occupies half of the world's habitable (ice-and desert-free) land.
