I did try to reduce the impact of what I eat, but I haven't found a replacement for using chicken with a slow cooker. Beef also tastes good, especially when I eat at a restaurant.
I have stopped making hamburgers on my own (and replaced them with fish or soup), but I haven't put more effort into reducing my impact recently.
I believe Skiff would automatically start using end to end encryption when it was available, without any user needing to enable it for any specific email, using the Web Key Directory standard: https://github.com/privacyguides/privacyguides.org/blob/1634bea9d2a66ef5804b68d18d4218e0b7a8b806/docs/email.md#openpgp-compatible-services
It's not good for me that an email provider that supports that is undergoing dramatic changes, as an open standard that protects my privacy is more useful when it is used with more services.
