Final answer:
The passage suggests that the greatest negative effect of technological change has been the homogenization of culture, as well as environmental concerns like pollution.
Step-by-step explanation:
The author of the passage suggests that the greatest negative effect of technological change has been homogenization, or the universalization of culture that leads to the loss of local cultures. While the interconnectedness facilitated by technology, including the internet and modern transportation, has allowed for a broader spread and exchange of ideas, it has simultaneously contributed to a more homogenous global culture. Meanwhile, developments such as transportation have enabled worldwide travel, but at the same time, pollution raises a major concern due to its negative environmental impacts. Globalization has affected various aspects of life, including economics, the environment, and culture, illustrating both the advantages and disadvantages of a globally integrated world.
