Why not ask your question on the new OpenStreetMap Community Forum?

Can you map and label areas that have environmental degradation (i.e. polluted lake, natural area w/extreme biodiversity loss)?

You can add the lake and vegetation themsevles. Biodiversity and degradation has verifiability issues. This is more appropriate for an external dataset, based on or linked to OSM data.

If it is signposted or otherwise indicated to the public, hazard=contamination can be used. landuse=brownfield is land previously as other facilities.

In particular, swimming=no may be used if it is not legally allowed at the polluted water body. (but this is not for suitability determined yourself)

Just one comment: brownfield land can be environmentally very rich!

Typical issues of degradation for land-based schemes could be treated using an appropriate plant_community. For water, although it has been discussed, I don't think there are accepted tags for eutrophication etc.

It is well-worth mapping potential sources of pollution/degradation for watercourses : things like sewage farms, slurry tanks & pits, silage clamps, industrial areas and outfalls.

Probably the biggest issue is that many landuse=meadow areas in OSM will be heavily treated monocultures of agricultural grasses (Rye-grass in the UK & Ireland) which often represent the largest loss of biodiversity across large ares of lowland.

Monoculture forest planted by reforestation after wars and fuel use has very low biodiversity too, not to mention vulnerability to diseases and pests.
