This is 2nd time we went to Portland Me for vacation. This is the Portland in Maine instead of Oregon. It's a port city.
I'd like to show you here is the old port area that we went. It used to be an industry district where there were many heavily polluted industries like Lead Paint, Coal mining company, etc. Around 100years ago, these companies paid no attention to the environment, they poured heavily polluted wastes directly into the water in the bay, leading to severe environment pollution. In the warm weathers, people dared not to go to the waterfront as it smelled so bad. The eco-system was ruined.
Luckily, people realized potential long term damage to the eco-system and took actions to clean up and protect the area. Now old port has become so beautiful and lively, the water is clean, the eco system resumed its livelihood.
We walked along the bay coast line, enjoying the breeze and beautiful scene the bay has to offer.
As you can see from the photos, there are many posts in the bay where they were used as landing deck in the old industrial time. We saw some fire burning charcoals on some of the posts. I guess there must be fire not sure when, but it burned down the old deck and left the marks forever on these posts. These posts have been standing in the water for hundreds years, it witnessed the evolvement of the old port, bad and good. Standing here, we have to feel very grateful for the eco-system we enjoy now.
