All this helps is true, but we must take into account the companies that produce the most waste, individually we can do what you say and more, but this is a collective effort and governments must focus on all this, however It is not convenient for governments to change fossil fuels and they play dumb, thinking that we are the ones who elect these people who, once they are in the position they want, nothing more than them matters.
What I do is give it to people who recycle and eliminate what is no longer useful, these people work on this and recycling also helps everyone.
