Most of the items/hobbies on the list are going extinct because they have been replaced by better options or were frankly not all that good of ideas to begin with. Not sure why that is a cause to mourn.
The only things on the list that we actually should mourn, that it is actually a tragedy to lose are:
Chesapeake Bay Blue Crabs
Ash Trees
Wild Horses
Honey Bees
The others are being lost because there are better options and time is marching on. This is true even of the family farm. The family farm can survive and compete, but a lot are being lost because the younger generations want to choose their own paths in life and forge their own careers. My great uncle complained so long and hard about the tough life of the farmer that when it came time to pass it on to one of his kids, none of them wanted to be saddled with it, they all had made successful careers in other fields.
No one is stopping anyone from writing a letter by hand. But now, instead of having to decipher my disabled mother-in-law's chicken scratches, I can read her email and she can get nearly real-time updates on her grandson. I haven't had a check get lost in the mail or fail to be correctly applied since the invent of the 'pay on line' option, which means I haven't paid an undeserved late fee in years. There would still be stand alone bowling alleys if enough people actually enjoyed bowling. I don't need an answering machine, my landline has voicemail.
I fail to see any good reason to be sad about the lose of Blockbuster, frankly if their corporate office gave a darn about customer service they'd probably have been able to survive.
Time marches on
