Although greenhouse gases are being emitted at an unprecedented rate, thanks to the Industrial Revolution of "the West" in the early 1900s, and now the modern industrial revolution of China, one of the main obstacles to carbon dioxide elimination is the work done by top soil: carbon re-uptake and sequestration.
The Soil Will Save Us: How Scientists, Farmers, and Foodies Are Healing the Soil to Save the Planet (2014) details how soil health and microorganisms in the soil will help ameliorate the cycle.
The main focus is that there is in fact a cycle of carbon dioxide release and re-uptake. This is like the human body, this is like every natural system that maintains its own biology and homeostasis.
Thus, we may not even have to change how we live too drastically, provided we can restore the natural cycles to balance. It's one question how far we are from balance, and it is another question if what we are doing will severely (and continuously) impact the reestablishment of balance.
The life cycle of earth's carbon dioxide is much like a mega body inhaling / exhaling. The process of breathing over the course of the seasons is absolutely magical to observe.
Repairing topsoil is no easy mission. It requires a lot of local efforts to generate rich organic compost. Typically, worms are the ones who turn compost into soil and make the whole process possible. It is quite amazing how two small friends: bees and earthworms, are so vital to the life of the planet. Like the left and right eyes of mother earth.
