Which physics relationship is more important?

How the absorption of infrared radiation by gases in Earth's atmosphere depends on wavelength; the resulting greenhouse effect provides us with temperatures that enable life to flourish.
How the absorption of ultraviolet radiation by ozone depends on wavelength; this absorption protects us from ultraviolet light from the sun.



Which unanswered question in physics is more important?

Does the Higgs boson exist?
Do quarks and leptons have internal structure? (Protons and neutrons are made of quarks; the electron is a lepton.)
