There is no really good answer to this. Heaven would suck big-time if there were no marriage, but it would also suck big-time if your late spouses were fighting over you. Which they would, unless heaven changed human nature. (Which it would pretty much have to, I guess, in order to maintain its status as a perfect place.)
In Vienna, there is a good enough rail transit system that it’s actually easy to live your life without a car. People do not die from rail transit nearly as much as they die from car crashes… plus, rails are easier and cheaper to maintain than roads, and electric trains are nicer to the environment than gas-guzzling cars. I do not see why the world has not completely replaced cars with trains yet. I mean, I can understand that governments don’t care whether 50,000 people live or die each year, or whether the environment gets wrecked or not… but you’d think they would at least care about their own pocketbooks, and maintaining rails instead of roads would save them a crapload of money in the long run.
That means that lions and antelopes each have at least two purposes: to feed/eat each other, and to make carbon dioxide for plants. Meanwhile, plants both make oxygen and feed antelopes. Everything has multiple purposes. (Except humans.)
Humans aren’t the first species to destroy the ecosystem’s balance, though. When the first plants appeared on Earth, they put so much oxygen in the air that it totally wiped out most of the other species that existed at the time (which were anaerobic bacteria or something, and so oxygen was deadly to them). But we have to be glad that happened, because that led to the evolution of oxygen-breathing species like us.
Maybe when humans destroy all the other species on Earth, it will usher in a whole new generation of life forms that breathe smog or something. We can only hope.
I don’t know what credit card company provides Abby’s check card service, but I have a feeling there really are companies like that around. Not mine, though. My check card comes from Visa through TCF Bank, and they charge the store a percentage of the cost, not a minimum amount.
