Some people just waste things and don't know there wasting .This could be simple things like:
Washing you dishes with a lot of water,
Turning on the shower for too long and not using it
and Leaving the television on when nobodys watching it.
Simple things can cause to bigger things and the bigger things may cause to problems.A lot of things happen in the background such as cutting down trees the size of football pitches litrally every second or keeping on the televion/computor for so long even though it takes up a lot of electricity. Some times you may have heard this saying that says ' Think before you react'. I my self am concerened about these things and want other people to know that too.
I may be sounding serious so you may want somebody to tell you a joke.
Just to let you know my name is Priya and I am eight.
