Biggest environmental concern

There so many things im concerned about when it comes to enviornment like what will happen, what were doing to it now and what we can do about it for the future. But what concerns me the most is blunt awareness. If people arent aware of themselves or see immedient repercussions then they dont care enough to make a diffrence. Stop what there doing, and make a change to there lives that will benifit everyone in the long run. I think thats the biggest problem is people not wanting to understand that whats going on right now , animals being poisonedand going extinct, our future water becoming more undrinkable per person , while eco systems changing,these  things need to be seen every moment of everyday . People need to make  individual chouices through out the day to choose to water a garden or conserve water in this drought. Stop buying tuna, ride a bike to work when they can becouse people who arent and dont want to be aware, are the ones who create the biggest problems. And the people causing the problems, buying gas, mulitple cars, litering, fishing for rare animals etc, big oil companies are our biggest environmental problem right now. And becoming aware. Of everything. Even ourselves.
