The governance of climate warming should be to find a way for carbon dioxide, not just to reduce emissions or simply bury it. To this end, scientists have proposed the concept of carbon-rich agriculture, which captures carbon dioxide generated by human activities, especially industrial production. At a concentration several times higher than the carbon dioxide content in the atmosphere, it is released in a small area of closed artificial climate, using related science and technology to create an efficient photosynthesis environment, thereby greatly increasing the yield of agricultural and forestry crops. Scientists believe that carbon-rich Agriculture will be an important way to address the issue of climate warming. If the following statement is true, which one supports the scientist's conclusions best? ? ['Traditional agriculture requires the use of land under the sun, while carbon-rich agriculture can be exempted from this restriction.', 'It is difficult to use sunlight efficiently in artificial climate areas to promote photosynthesis.', 'Modern technologies can capture, transport, and release carbon dioxide at a lower cost.', 'Carbon-rich agriculture can use saline-alkali land, desert land, desert land, etc. to solve land shortages.']
