Pollutants should be treated consistently

[cmungall]

Ontology:

rdfs:label "environmental pollution"
definition "An environmental system process that results in the introduction of contaminants into an environment."
rdfs:comment "Pollutants may be material or immaterial (e.g. heat energy)"
has_exact_synonym "pollution"
in_subset "environmental_hazards"

'has output' some
('environmental material' and ('has increased levels of' some
('chemical entity' and ('has role' some 'environmental contaminant'))))

My comments:

If thermal pollutants are a kind of pollutant then the overly complex logical axiomatization isn't correct.
