The latest two research results have attracted people's attention: one is to use certain bacteria to produce artificial meat protein, which grows by absorbing the greenhouse gas carbon dioxide, which takes about 2 kilograms of carbon dioxide for every kilogram of protein; second, to synthesize ethanol from carbon dioxide and water recovered from the atmosphere, it takes 1.5 kilograms of carbon dioxide to produce 1 kilogram of ethanol. Experts predict that these new technologies will help to achieve the goal of zero greenhouse gas emissions in the middle of the 21st century.
It can be concluded that only the resource utilization of carbon dioxide can achieve zero greenhouse gas emission based on this.
