We don't have to stop emitting all carbon dioxide, we need to develop the technology to capture and sequester what we do emit, however.
I personally calculated that planting trees would be thousands of times more cost-effective than driving Tesla vehicles: https://news.ycombinator.com/item?id=19714034
Cutting down a fraction of industrial activity- which represents a fraction of human-made CO2 output, which is only about 5% of mother nature's CO2 output- seems a lot less efficient than improving upon mother nature's own carbon sequestration schemes. It's better to sequester potentially all of the CO2 in the atmosphere instead of targeting a fraction of a fraction of a fraction of atmospheric CO2
The answer has to be to apply technology. Cleaner energy generation and new (or old) methods to sequester CO2.
