Look at LA skid row has created diseases from the middle ages.. 

Thank you @Dave Foster I look forward to my new venture and investing in real estate hoping to achieve financial freedom and enjoy my life with my kids and my beautiful wife that has a terrible debilitating autoimmune disease.

I have been buying a small pharma company in the opthalmic space, Harrow, HROW since May at $10, with good growth prospects and in an area with long horizon of medical need for the diseases it treats, they keep announcing better earnings each quarter, and stock now $44 in just 3-4 months, I've bought other companies with good products in the past like NVidia back in 2009 as they made the best graphics chip, G-Force, for gaming.

Instead, Trump calls for Health and Human Services Secretary Alex Azar and Centers for Disease Control and Prevention Director Robert Redfield to “consider” whether an eviction ban is needed.A federal eviction moratorium has ended.

Disease?

If you sue, and have to "prove" that the neighbor was negligent, then that would likely need to consist of multiple “written” communications from you, the city, or an arborist to your neighbor stating that you/they feel the tree in question is diseased, appears to be dead/dying, is overgrown and posing a potential threat to your property, etc.

Mankind always comes up with a work-around for Govt overreach (At least in the US)..... 

Addiction is the disease of chronic relapses and heroin is a monster, so issues do occur.

That is the biggest regret to mankind.

State law is not on your side, you often deal with desperate people dealing with the four "Ds" (Death, Disease, Divorce, and Disaster), and the home runs that get the glory on social media are rare birds indeed.
