The CO2 from human exhalation is small compared to the CO2 from fossil fuel combustion. Despite the large increase in human population, the CO2 from humans and other animals is mostly offset by plant absorption of CO2. It's the large-scale combustion of CO2 that upsets the balance.
What to do about it? With our current technology, the only economical alternative to fossil fuels is nuclear fission. For some reason, people still fear nuclear power despite its excellent safety record (even including Chernobyl and Fukushima).
