Nobody was ever worried about the planet. We are worried about the ecosystems that we rely on to survive.

Even just a primer going off with no powder or bullet could cause serious injury or death, if the gun was held against your head.

This won’t affect us on earth. We will just be able to see it.

You are correct about everything but I feel I should point out that the amount of heat produced by an incandescent bulb in your fridge is miniscule compared to the heat energy of the warm air that enters your fridge as soon as you open the door. Cold air sinks due to its density and so when you open the door it all falls out and your fridge must work it’s ass off to cool all the new air back down to the set temperature. The heat added by an incandescent bulb for a few seconds is basically irrelevant.

This is also why chest freezers are so tremendously efficient. When you open the lid, the cold air stays inside. Very little mixing occurs with the rest of the environment.

but we can all see where that led!

It led to the LED!

Nobody is claiming or worried that all life will go extinct. What sucks is that we are fucking over all the animals that we know and love. If elephants go extinct, there will never be elephants again. Same with whales and koalas and sloths and bees. They will all be gone forever like dinosaurs and dodo birds and thylacines and trilobites.
