Picking up trash that you see will help out more than you think. Where I live everywhere I look is litter. Lots of people don't know where the litter goes and thinks someone will eventually pick it up. I live near a coast and trash eventually ends up there. Once trash enters the ocean it harms the species living there. Many corals have died due to pollutions in their habitat and many turtles, whales, etc. have died from the harmful trash effecting them. The Pacific Garbage Patch is also expanding by a lot and we need to help.

Picking up trash is certainly a great way to not only benefit the environment but eventually lower CO2 emissions. I believe that in conjunction with picking up litter, actually recycling and composting what can be recycled and composted as a great way to lower CO2 emissions and greatly aid the environment. I say this because according to  a new study led by the National Center for Atmospheric Research it is estimated that more than 40 percent of the world's garbage is burned in order to get rid of it. And being that roughly 40-50% of garbage is made of carbon, the burning of it is very detrimental to the earth's atmosphere and adds a large amount of CO2 to the atmosphere.

In my opinion although it is a little annoying, recycling and composting are actually much easier than doing other things to lower CO2 emissions like going vegetarian and it is still very beneficial to the environment.
