Bury The Bad Stuff

Carbon dioxide is the most prominent greenhouse gas contributing to global warming. According to the Energy Information Administration, by the year 2030 we will be emitting close to 8,000 million metric tons of CO2. Some experts say it's impossible to curb the emission of CO2 into the atmosphere and that we just have to find ways to dispose of the gas. One suggested method is to inject it into the ground before it gets a chance to reach the atmosphere. After the CO2 is separated from other emission gases, it can be buried in abandoned oil wells, saline reservoirs, and rocks. While this sounds great, scientists are not sure whether the injected gas will stay underground and what the long-term effects are, and the costs of separation and burying are still far too high to consider this technology as a practical short-term solution.
