How would you protect the lab's exoplanet pods in the most effective, practical and noninvasive way, considering the species and the fact that we are on an exoplanet?
1) By creating a force field around the pods
2) By using camouflage technology to blend the pods with the environment
3) By developing a chemical repellent to deter species from approaching the pods
4) By constructing a physical barrier around the pods
5) By implementing a sound-based deterrent system to keep species away from the pods
