:Lots of comments on this thread on the death rate.If you have damaged lungs, such as due to pollution (Wuhan) and smoking (60% of Chinese Males smoke), CoronaVirus is much more deadly. 

The likely hood is that based on the age of the community the cottagers are polluting the lake, E.coli counts are probably up in the swimming area during the summer after a rain and at some point it will be discovered.

Satellite images have shown a dramatic decline in pollution levels over China, which is "at least partly" due to an economic slowdown prompted by the coronavirus. 

I'm sure my lungs will also appreciate me being out of this horribly polluted air.2.

Lots of traffic and pollution.

Some countries like China have to think about how much to pollute killing people that way vs starving people to death every day. 

The oil is pollution and seeps into the soil, possibly the groundwater. 

Or, is someone just tired of the signs, which are illegal in some communities, may be illegal without first paying for a permit, or simply considered a nuisance by someone living or working in the area and you are polluting their neighborhood in their mind?

Whole foods  Safeway and our local high end store Zupans all within 3 miles of me and since I am going in the Tesla I am not polluting either LOLmiddle road is those clubs that send you meals .. that you simply cook I tried that.. but I don't like others picking out my veggies etc.. or touching them .. and they wrap everything so it takes a bunch of time to unwrap one radish that is in plastic waste of energy and not very environmentally friendly..
