A city plans to convert all of its electricity
sources to solar collectors. This is one part of a
new plan to manage the city’s energy
resources. How will this plan most likely affect
Earth’s systems?
A. Air pollution in the atmosphere will decrease.
B. Water used from the hydrosphere will
increase.
C. There will be more mining of fossil fuels
from the geosphere.
D. There will be less food available for animals
in the biosphere.

A. Air pollution in the atmosphere will decrease.

Explanation:

Electricity is among the purest energy sources. Although production of electricity  will cause a lot of environmental pollution. A common way of producing electricity is through burning fossil fuels.  The combustion of coal and natural gas results in smog, acid rain, soot,  global warming and carbon pollution. It also generates significant quantities of waste including sludge, hazardous chemicals and heat. However, solar panels works on the solar energy and therefore helps to decrease in air pollution.

so i really think that most of the health care industry be doing more bad than good.
