How to reload environment variable in shell script without restarting Linux server

I want to set a environment variable globally for all users in linux.

In order to do that I modified /etc/environment file.

For example at the end of file.

sudo sh -c 'echo "\nmyenv=hello" >> /etc/environment'

After executing this command when in run in the same terminal.

echo $myenv

i'm not getting the value hello.

After typing the below command.

source /etc/environment

I'm able to access the environment variable in command prompt with 

echo $myenv

But the problem in this method is if i execute a sh file. Which is accessing the $myenv. I need to again type the command
source /etc/environment in that shell script.

Please let me know what is going wrong here.

Please suggest me what is the approach followed here.

I don't what to logoff and logon or restart my server.

An environment variable is only inherited by child processes if it is exported.

myenv=hello
export myenv
