Many people still have a hard time believing that their thoughts create the world around them, their experiences, even their afflictions. But look around you, look at your friends, look at the place where you live, look at the stuff you own, look at your job and your hobbies. Haven't you created all of it? If you have a beautiful garden you love gardening and you created it. If you have a negative friend and don't appreciate him/her reflect on why that person is in your life, then make a decision. It's your intentions, your efforts, your thoughts and beliefs, what you did and did not do, what you did and did not think and believe that is reflected in the world around you, individually and as a culture.
If you don't like what's happening with the environment you need to do something about it on a personal level, change apathy and acceptance to thoughtfulness and action. If you don't like what you see, if you don't like what and who you are, dig deeper to uncover why and how you have created what you have created. Inspect the underlying beliefs and thoughts that went into it. It takes some work, it might be tedious. But who said it was easy?
Today's thoughts create your future. If you think the same thoughts today that you thought yesterday your future will look like today. If you don't like today you need to change your thoughts and beliefs today to create a different future.
So what would you like your future to look like?
