Final answer:
People's reaction or conscience can vary depending on the specific event or situation and various factors such as personal beliefs, cultural values, and social norms.
Step-by-step explanation:
If such a thing really happened on our planet, whether or not people will stir up their conscience would depend on the specific event or situation. People's reaction or conscience can be influenced by various factors such as personal beliefs, cultural values, and social norms. For example, if a significant environmental disaster occurred due to human activities, people might feel guilt and empathy for the harm caused and become more conscious of the need for sustainable practices. On the other hand, if it's a matter related to controversial topics like politics or religion, people's reactions may be more polarized, and conscience stirring might be less prevalent.
