I’m can say that, for our family at least, adoption was an alternate route. There are many, many children here in the US who’s parents have died or who whose parents have had their parental rights terminated for cause. 8 years ago we adopted a 3 year old and a 7 year old, and the lack of biological link barely matters (it only comes up due to racial differences).

If you are a basically decent human and can support yourself and a child, give a look at adoption rather than having this regret for your lifetime.
