Buddhism and the surrounding environment

**EDIT** At the request of yuttadhammo and Lanka, i am attempting to focus the question. Please let me know if it still remains unclear. The environment is full of daily encounters through the physical, visual, auditory, mental and emotional faculties. Some of these interactions are positive in that they help promote the well being of one-self and other whilst others are negative. It seems all is an illusion especially when some of these interactions out-weigh the other e.g. positive vs negative and vice versa. Often this feels like a battle to bring more positive in light of the negative. The emotional and mental effort required to keep forging ahead seems futile. Repeatedly i am told that meditation is the path however i fail to see how when it seems that it is intended more for me than for me and others. I feel like a battered and wounded lion or soldier. I feel lost. Concepts are unedifying since they further cloud the situation e.g. where truth end and lies start, where right and wrong are right and wrong, etc What does one do? **Original Question** The definition of environment in the context of the question is to do with the daily encounters one has with the world be it through physical interaction, auditory, visual, emotional or mental. Each day, these interactions are positive or negative. An example of positive may be someone assists another in need of help. An example of negative may be when someone is not conducive to the problem or issue at hand or a war stricken land. Sometimes the positive outweigh the negative and vice versa. Sometimes it feels like a battle to bring positive possibilities as you are attempting to shine light in a large area of darkness. - How does one approach this? - How does one remain motivated? - How does one help another through their suffering? - How does one trust another? I may be wrong in my understanding however meditation appears to be an activity for oneself. It does not encompass the wider world. If all is interdependent and interrelated, is this not futile?
