A drop of rain is small indeed, but many drops can fill oceans.
It is scary indeed, to think we can't help raise children unless we give birth to them ourselves, while ignoring millions of struggling kids today. Why can't we love them as our own? Ultimately, we all come from the same source [1].
Hard to relate to you, but you can try to understand.
Insulting to our ancestors? Is it really, if one's making this decision for the love of all life on Earth, wishing to reduce harm and suffering caused by our unsustainable way of life?
Pessimism. Optimism. About the climate. Not about the climate. Deeply off or deeply on. We can do psychoanalysis all day, but reasons for declining birth rates are well-researched. The world is not running out of humans anytime soon, while nature and other living beings could use our help (or lack of harmful actions) now. So let's do that.
Resources are finite. The world is not only ours, what about the animals and plants? Are we giving them enough space to thrive? Killing them will kill us, and our children too.
What PR and lies have you fallen for, to say individual actions don't matter? Actions have consequences. Each action is a vote. One vote doesn't matter, a lot of votes do. What are you voting for?
Giving love and safety to children who need it now is a noble act. Totally different? Maybe. But love is love. All humans come from the same source. No need to discriminate, let's spread love to all.
