Step by step
- Define the key terms. Decide what “moral imperative” demands, and what counts as “colonization” rather than exploration or research.
- Choose a framework. Pick the value and standard your case will win under, and prepare to answer the framework your opponent is likely to run.
- Build the contentions. Write the arguments that link your side to the standard, with evidence for each claim.
- Search existing evidence. Search Card it’s 2026-27 LD set to see what teams are reading, then read the original sources.
- Write and drill blocks. Prepare responses to the arguments you expect, and practice them out loud.
The resolution, term by term
- Moral imperative: a duty, not just something that is permissible or good. The affirmative has to show that colonization is required.
- Outer space colonization: establishing permanent human settlements beyond Earth. Expect debate over whether research bases or resource extraction count.
- No actor is named: the resolution is about morality in general, so frameworks and standards do most of the work.
Common lines of argument
This is not a complete list, and evidence will decide which arguments hold up.
- Aff: reducing extinction risk by spreading humanity across more than one planet, scientific and technological progress, and expanding humanity’s moral horizons.
- Neg: resources and attention are better spent on problems on Earth, the ethics of colonial expansion, protecting other worlds from contamination, and risks to the people who settle.
- Frameworks: consequentialist, deontological, virtue and justice-based standards can all be argued, so be ready to compare them.
