What would most likely happen if the carbon dioxide in earth's atmosphere were reduced to half?
a. earth's surface would become cooler
b. the ozone layer will become thicker
c. there would not be enough oxygen to breathe
d. earth's air pressure would increase dramatically

all fossil fuels are nonrenewable, so think coal, gasoline, things that we will eventually run out of. all fossil fuels are nonrenewable resources, but not all nonrenewable recourses are fossil fuels. these resources are not being renewed as fast as we are using them. i hope this considering there weren't any answer choices.
