Use your bike whenever it is possible instead of your car. By the way it is also good for your health not only for the environment.
Buy products that are produced in your neighbourhood and are not shipped twice around the world.
Shipping, yes. That is a great polluter - good shout - though it primarily applies to food right? It's tricky to buy everything locally-produced e.g the mac I'm typing on. Shipping exists in part because raw materials are spread throughout the globe.
There is a lot of finger-pointing going on. Every proposal for a solution which involves me changing the way I live is a red herring. The industry I am working in is not responsible for killing our environment. The car I drive is much harmless then the meat you eat. Turning off my TV set and reading books or going on a walk instead would not save the world until everybody follows my example so why not spend 5 hours of my free time every day in front of the screen? Everything - except talking online about what others should change in their lifes to protect our enviroment - is too uncomfortable for me so let's use Rust or Go instead of the inefficient Python because this will save the world from humanity.
Yes it will, if you work on Skynet. Otherwise won't.
