Automobiles are a commodity that has a greater impact on the environment. It seems natural that automobile manufacturers support environmental protection causes and carry out environmental protection propaganda. Environmental protection should be a factor that must be carefully considered in the development of automobile companies, but it is required that automobile companies have no profits or even losses. Environmental protection is obviously unrealistic, and it will not last. Auto companies are adopting new technological measures while minimizing environmental pollution and meeting the general trend of social development. The core point of this passage is:. ['There is a contradiction between environmental protection and the realization of corporate profits.', 'Development of environmental protection cause should focus on starting from reality.', 'Technical innovation is the key to solving the environmental impact of automobiles.', 'Auto companies should pay full attention to environmental protection while developing.']
