Passage Summary: Because satellites are so helpful for protecting the environment, it makes sense that environmentalists don't want to think about how the rockets used to launch them might actually be hurting the atmosphere.

Conclusion: It is understandable why environmentalists overlook the potential for spacecraft to cause significant damage to the ozone layer.

Reasoning: Space-based satellites are a major breakthrough for environmentalism because they allow for early intervention in ecological crises.

Analysis: This argument describes a situation where a group ignores a negative side effect because the positive benefit is so significant. We need a principle that justifies this behavior or explains why a group would focus on the benefits of a tool while ignoring its drawbacks. The logic follows a pattern of 'When something provides a massive benefit to a cause, those dedicated to the cause are likely to ignore its potential harms.' Look for a principle that connects the importance of a tool's function to the tendency of its users to overlook its flaws.
