Old money that felt entitled and just wanted to maintain the status quo, and those i would willingly assist in throwing off the Golden Gate Bridge but that would likely lead to water pollution and sick fish. 

In the meantime, the pollution continued to grow, and the cost to build and building codes created a situation that prevents the mass building of affordable properties. 

I've had guests dump ashes into the bluff, which drains to the lake and can pollute it. 

Now I'm realizing that for this whole idea to fit in line with my values I'd really like to use my investing to not only create a passive income for myself but also to contribute to making low socioeconomic urban neighborhoods better, particularly for kids who grow up in those areas, like helping them be less exposed to toxic substances and pollution, or have safer neighborhoods to play in, or more access to health/education resources. 

A major component of these solar companies operations is selling the energy / EPA credits  - to companies that pollute (oil refineries, coal fired power plants), and when they buy the credits it allows them to pollute that much more.  

Double pane windows offer reduced outside noise pollution, and are energy-efficient.

The first estimator pointed out that it's obvious the reason the old unit isn't working, the refrigerant lines have been pulled off the unit (and sadly all the old (Freon) refrigerant has escaped, polluted the atmosphere).  

I agree with Mike...noise pollution is something the neighbors didn't sign up for and i think it's important to address the issue.

You want to pollute your lungs, you're addicted I get it but Butts are trash don't throw on the ground or out your car window...  

Pollution dropped, outside litter reduces, plastic bag reduction etc.
