Answer:
The correct answer should be: "It is important to reaffirm and test technologies' importance and impact to society in order to reflect upon their benefits or damages to the environment".
Explanation:
Technologies have a major importance in society nowadays, although they also have a great impact in the environment, whether for good or not. The fact is that reviewing and assessing technologies' importance and impact are necessary to test and garantee if they have been developed in an environmental friendly manner or with no worries for natural resources and society. Therefore, any technology must be ethical in terms of improving society with no damages, or as least as possible, to the environment.
