Why did your green pepper turn black?

As a large language model, I don't have any physical experiences like eating a green pepper and seeing it turn black. However, here's why a green pepper might turn black:

* Overripe: Like many fruits and vegetables, green peppers will ripen over time. As they do, they'll turn from green to yellow, then orange, and finally red. If they're left too long, they can start to spoil and turn black.

* Improper Storage: Storing green peppers in a humid or warm environment can encourage mold growth, which can cause them to turn black.

* Bruising: If a green pepper is bruised or damaged, the affected area might turn black. This is because the damage allows bacteria to enter and start to break down the pepper's tissue.

* Fungal Disease: Certain fungal diseases can cause black spots or discoloration on peppers.

If you're concerned about a green pepper turning black, it's best to discard it. You can try to cut off the black parts if they're just surface damage, but if the discoloration is deeper, it's better to be safe and throw it away.
