We call it the global environment.

So let's start with the global environment.

Step 2 Are we the global environment?

Otherwise, if I'm not the global environment,

In our global environment, greeting points to hola.

This environment knows that it was created in, defined in this global environment.

One variable in the global environment one local variable maybe even no variables in the global environment should be totally fine.

Every environment that's not the global one has a parent.

The first thing we do is make a global environment.

Here's our global environment. x is 11, y is 22.

Okay, eventually we'll have to get it from the global environment.

Step 3 If we're not the global environment, ask our parents.

Well, in the global environment x is 1 and y is 2.

Suppose we had access to the global environment so this is actually defined, and instead of passing in the current environment, whenever we make a function, we're going to pass in the global environment instead.

With only one function in our program, we'll have our top level global environment and then the environment for our new function, and we're making its declaration, or its parent pointer, go back here to the global environment.

We need at least three variables in the global environment to see the bug.

So then after we look up y in the global environment, we make a change.

And it has no rules to its regulatory system.

We assign x to be 55 in the new environment, and then we print out x in the new environment and the global one.

Today, each of these elements is opening up due to dramatic changes in the global environment.

If I look up y in the global environment, the answer is similarly right there 22.

The second, we need at least three variables in the global environment to see the bug.

But if we are not the global environment, if I don't have it in my pockets,

If I am the global environment and I didn't define your variable, then this is problematic.

If we were the global environment and we didn't know the answer, then we'll just return None.

So this is analogous of having a global environment a big marketplace where you could buy new keys.

And the human impact on the global environment greenhouse warming, mass extinctions and so forth is unprecedented, too.

As a company with global reach and global interests, we have global responsibilities.
