I think this is just not right money wasted,dumping in our ocean,harming marine life etc.... Even though it make new home for the animals it's still harming the old one below it. Let's say some fish eggs were at the bottom of the ocean the BAM a subways car comes down and ruined the eggs! I don't thinks its right you can say other but i don't think it's cool! AND THANK YOU IF YOU READ THIS (i'm not yelling I just put in CAPs to get your attention)
The way they prepped the cars was taking everything out like the seats, the straps, the electricity powered engines and they had to clean every inch of it which must have been a lot of work. It seems cheaper to throw them into the ocean than deal with the asbestos. It helps the fish hide from predators like shark and barracudas so they can swim through and escape.It may seem dangerous to marine life but it also gives them food that grows on the side of the cars like barnacles and other things that they eat so its kind of a win win for us and the fish.
I think its a good idea that they are doing this because they are putting the subway cars in areas where natural reefs couldn't grow so they are making fake habitats for fish with subway cars. it is also good because it is kind of like recycling the subway cars for cheaper. They prep the cars by taking out the whole entire interior including seats, straps, wheels and washing it down.
