You can take no action, but the terrible thing is you can't have no consciousness about it.
It is very common that we see beggars everyday. It's ok that you don't give money to them, maybe you say, i have no change at this moment, our government can help them, they are false ones, they are cheaters, they are lazy guys, but you can't have no feelings to them, at least you should feel that you are very sympathy for them. A good conscious is extremely precious. They are poor guys, many of them are really need your help. They are suffering miserable life, you know that. Some of them are disabled people and they have probloms to face their hard life and even have lost the ability to take care of themselves. Yes, some of them are pretending to be poor guys and asking you for money, that should be condemned, to them, you have the right to choose to help them, but you don't have the responsibility to help them. You should learn to tell what is right and what is false in the world, know who is the real poor people and who is the deceptive people who want to take advantage of your kindness. 穷则独善其身,达则兼济天下。If you are rich, you can take care of other people, otherwise you take care of yourself. Just try to help these suffering people, no matter how much you do. I'm sure that when you help someone real need people's help, you will have a good mood all day. Don't delay your assistance to others, to help others is to help ourself.
It's commom that we see garbage everyday. It's ok that you don't pick it up and throw it into dustbin, coz the cleaner will do it, but you cannot have no environmental protection consciousness, to care for the environment means to protect our earth, protect our mother. If you continue to pollute the environment, i'm sure that the end of the world will come soon, more fast.
It's common that we turn on the lights and fans and air-conditions all night. It's ok that you need them, but it is not ok that you forget to turn off them when you leave, it is not ok that you don't have the consciousness of saving, you don't know to save resources. Some resources are nonrenewable, unrecyclable, when we run out of them, it can never be made and got. So the consciousness of saving is very important. In our daily life, you can start from little things, save water, save paper, save power, and so on and save your money if you want and like,haha
I believe that once you have these consciousness, actions won't be far away. Just do it, make efforts to make the world a better place to live and make you a happy life! Cheers!
