Cleanup is great. Mowing lawns instead of letting them grown removes one of the last remaining habitats for animals living close to humans.
Clearly you've never owned a home with pest problems nor dealt with animals chewing the wiring harness on your vehicle or inhabiting its air intake circuit.
I'm all for conservation and limiting human population size but there's no sense in encouraging pests to live in/around your house and possessions.
You're right, your sample of one clearly proves the absurdity of it.
(But also I'm with the sibling comments here -- lyme's is no joke and I'm terrified to know that it's been migrating west)
1.3 acres for $6k where you can cultivate whatever plants/habitat you want.
You can buy large acreage in the city of Detroit pretty inexpensively. The city itself will sell you individual house lots for $100.
Sounds like a great opportunity for all the wildlife proponents in this thread to do their share and create a natural reserve where they believe there should be one. That's far more productive than criticizing volunteers for mowig a lawn.
