The two ground wires must be wire-nutted together along with another 6-inch length of green or bare ground wire known as a pigtail. A grounded electrical outlet has three holes to provide a ground connection for three-prong plugged devices.Sep 26, 2017
Can I connect grounds together?
You connect all the grounds together with a ground crimp connector. A wire nut is not sufficient to meet code. And then if the box is metal, you connect the crimped bundle to the box. Leave one of the ground wires longer than the others, sticking through the crimp connector, and attach that one to the box.
What happens if you do not connect the ground wire?
If the ground is not connected (bonded) to the neutral, or the system ground is not properly grounded to the Earth, two bad conditions will exist: zero voltage will not have a ground reference, which can lead to irregular and inconvenient voltages that could have a negative effect on equipment, but more importantly, ...
What does the ground wire connect to in a light fixture?

Is it OK not to connect ground wire?
As long as one of the two are grounded, there shouldn't be a problem. Code bodies and safety experts say to bond both the fixture and the box, because there's no way for them to be sure that a fixture will properly bond during installation.
What happens if ground wire is disconnected?
One problem with this arrangement is that if the ground wire is broken or disconnected, it will not be detectable from the operation of the appliance since the ground wire is not a part of the circuit for electric current flow. ... The ground wire of an appliance is the main protection against shock hazard.
Is ground wire really necessary?
The ground wire is not strictly necessary for the operation of a device, but it is still an important feature. This wire is designed to provide a path for electrical current to travel if the normal paths aren't available. This could be because the other paths are damaged, or there is too much electricity for them.
Is it acceptable to join a grounding wire?
No you can't.
Can you extend a ground wire?
Technically, you should twist the extension bare ground wire to the short one and secure it with one of the copper crimps like you have pictured. A wire nut certainly would work , but it should be green. Practically speaking, either way will work and be safe, just a matter if you want to follow current NEC standards.
