If we want to have any chance of surviving, we are going to have to change quite a few things.

We need to stop being so wasteful.

We need to stop polluting.

We need to deal with all the pollution we've already caused.

We need to stop making food that has no nutritional value, or even worse, is full of poison.

We need to start accepting that everyone is different, and have their own beliefs.

We need to stop actively and needlessly committing harm, both to each other and to the other life forms we share this planet with.

We need to start accepting that we share this planet with others. The world does not exist for us alone.

We need to stop allowing ourselves to be led by the corrupt, and to start playing a more active role in our own governance.

We need to start accepting responsibility for our own actions, and recognizing the effects our actions have on others.

And the list continues. There are many things we need to change. There is a lot to be done, and a lot to be made up for. But it can be done. It must be done.

We can start by being nicer to each other. Start today. Avoid making a hurtful remark. Hold a door open for someone. Give a friendly hello to the cashier at the store or bank, the gas station attendant, or whoever else it is that is providing a service for you. Smile at a customer, or a random person on the sidewalk.

Every person, every living thing, deserves your courtesy and respect until such time that they do something that warrants otherwise. If you can't be bothered to show it to others, then you're not worthy of it yourself.
