proofread my essay please- GRammer?

Grammar and word usage -
1st sentence -change "avoid" to "not" - change "and" to "or"
"reduce loss of hearing" is not clear enough. How about can "be safer".
take the s off the end of "consider".
2nd sentence - take the s off of motivate
put a comma after distance and put a period after test
Make another sentence beginning with Often and change "does not" to "don't"
Next sentence, spelling on "danger" is wrong, and put a comma after "nearby". End this sentence after road. Start next sentence with "This" is often ...
Next sentence check the spelling of themselves. Add the word "can" after "they". I would remove "should not be involved with the accidents". Then put "innocent" before "pedestrians", and remove "the".
Next I would leave out "as a student of my school".
Next, change "where" to "when".
Remove sentence starting with "I believe...." Change next sentence to "Many individuals have..." Put a comma after heal, and drop the word "of". I would also recommend saying "foolish" instead of "lousy". Instead of who "cannot concentrate on biking", say who "shouldn't be" biking...
Hope this helps.

Avoiding listening to music or talking on cell phones while biking can reduce the amount of hearing loss a biker experiences; many people think listening to music while biking is a fine way to entertain and motivate themselves. They believe music can motivate them to continue biking over longer distances as it entertains them after a boring class or stressful test. But often, too many people don't realize the danger it can present. Those who listen to music while biking cannot easily tell when danger is nearby because they're not 100% concentrating on the road, which is the cause of many accidents. Besides endangering themselves, they also create harmful conditions for pedestrians and other bicyclists. As a student, I've personally experienced this. I was biking on a crowded road, where suddenly someone crashed into me from behind. I fell immediately. The person who crashed into me continued to bike off, still talking on his cell phone. Luckily, only my ankle was injured. I believed that there may be many unlucky individuals with serious injuries from bike crashes that never fully recover. The cause of the problem? Thoughtless, careless, unaware individuals who cannot concentrate on biking because they are too involved in listening to music or talking on cell phones.

Although avoid listening to music and talking on cell phones while biking can reduce loss of hearing, many consider listening to music while biking a way to entertain and motivate themselves. They believe music can creative motivation for them to continue biking for a longer distance as well as serving as entertainment after a boring class or stressful test. However, many do not realize the danger this act may have behind it. Those who listen to music while biking are not able to tell when danger is nearby because they cannot concentrate on the road, which is often the cause of many accidents. Besides hurting themselves, they also cause harm to the pedestrians and other bicyclists who should not be involved in the accidents.

As a student of my school, I personally experienced such an occurrence. I was biking on a crowded road, when all of a sudden someone from behind crashed into my bicycle, causing me to fall immediately. The person who crashed into me continued to bike off while talking on his cell phone. Luckily, only my ankle was injured. I believed that there are not many lucky individuals like me who have light injuries. Many of them have injuries from bike crashes that can never fully heal due to a few lousy individuals who cannot concentrate on biking while listening to music or talking on cell phones.
