We are for cleaning the environment and keeping it clean. Actually I would say that the environment is much cleaner than it has been before in the US. The environmental laws, which were non-existent in the 50s and early 60s are very strict.
Out here in CA when the air pollution is bad, they call a "Spare the Air Day". In the SF area,two summers ago we had maybe 2 or 3, caused by temperature inversions, where warmer air aloft kept the pollution concentrated at the lower altitudes. These were usually very hot days (105-115 where I live). This was a lot less than the 10-15 they had regularly in the past. This past summer, we had a lot more because of the hundreds of wild fires, the vast majority of which were caused by lightning.
When we don't have the fog rolling in, which is often, you can get spectacular views of SF from Oakland or even near Palo Alto , down the peninsula over 20 miles away.
The fires were so bad this year we could smell the smoke from the nearest fire which was about 50 miles away. It was so thick that the ridge 2 miles from my house was almost obscured.
I was in San Jose one day in June. There was a massive fire (at least 50 square miles burnt) about 100 miles south. The wind shifted and it looked like a thunderstorm was rolling in. It was the smoke. Everything had an eerie orange glow. I even thought I saw snowflakes. It was ash from the fire coming down.
