Sonic boom is that when the aircraft breaks through the sound barrier, due to the compression of the air can not spread rapidly, it will gradually form a shock surface. The highly concentrated acoustic energy on the shock surface causes a loud sound, which makes people feel a short and extremely strong explosion. Sonic boom occur only when they break through the sound barrier, that is, flying at supersonic speeds. The sonic booms cloud is a conical cloud with the aircraft as the central axis and spreads uniformly from the front of the wing to all sides. It is mainly due to the fact that the velocity of the air flow is faster than the conduction speed of the air when breaking through the speed of sound, which can not effectively pull down the airflow, resulting in a decrease in density, a decrease in air pressure, and water vapor condensing into tiny water droplets, which looks like a cloud-like state to the naked eye. Sonic boom cloud often appear in transonic flights, but not only in transonic flights.

A common non-stick coating for non-stick pans is Teflon coating. Ammonium perfluorooctanoate is a processing aid used in a very small amount in the production. Data suggest that high doses of ammonium perfluorooctanoate may lead to elevated cholesterol levels, thyroid disease, and infertility. Teflon has very stable physical and chemical properties at normal temperature and normal conditions. Cookware with Teflon non-stick coating will not change in the temperature range from normal temperature to 260 °C, but when the temperature exceeds 260 °C, the coating will not change. The layer gradually transitions to an unstable state, and decomposition occurs when the temperature exceeds 350 °C. During normal cooking, the boiling point of water is 100°C, and stir-frying with a higher temperature is usually only about 200°C. Even if frying is used, the oil temperature will not exceed 250°C.

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.

Question: Based on this, it can be concluded that which of the followings is correct?

Choices:
- A.Using carbon dioxide to produce food and alcohol will become a new industry
- B.In the future, man-made foods can reduce their emissions by eating carbon dioxide
- C.Only the resource utilization of carbon dioxide can achieve zero greenhouse gas emission
- D.Carbon dioxide resource utilization may achieve zero greenhouse gas emission target
