  By using a language as accessible to a broad audience as possible, in this
note we present evidence suggesting scientific caution prior to final claims
that neutrinos and quarks are actual physical particles existing in our
spacetime. We review historical and recent evidence dismissing the existence of
neutrinos and quarks as physical particles, and outline recent theories
representing experimental data without their existence. We also identify the
negative implications for environmental issues of the neutrino and quark
conjectures since they imply the suppression of due scientific process on new
clean energies predicted by new structure models of hadrons with massive
physical constituents produced free in spontaneous or stimulated decays. The
note ends with the need of continuing theoretical and experimental research on
neutrino and quark conjectures, but complemented, for evident scientific
democracy, accountability and societal needs, with theoretical and experimental
studies on alternative theories without the neutrino and quark conjectures and
their prediction of new clean energies.
