That would be amazing. Unfortunately, there will very likely be no aliens to do it. We’ll have to do it ourselves.

Just like the blue whales, they are now turning silent as their natural habitat is dying.

Yes, that is great on an individual level.

But the best thing to do overall for our environment and climate is supporting protest movements, especially those employing nonviolent civil disobedience. Per pound/dollar/euro, they reduce emissions the most. But if you can, attend events in person.

This should not neglect that we need both individual and system change and they depend on each other. You should reduce your meat consumption and advocate for a world where everyone reduces meat consumption (and even become vegan or at least vegetarian).
