opinion essay

can you help me to check my opinion essay?

Many people eat junk food every day without knowing who made it and from what it's made. And I think this is not good because maybe it's made from harmful things and it may cause cancer or even death!!! So people should stop eating junk food in order to be safe.
Now days people think it's better to eat junk food cause it's faster and you don't need to make it by yourself you just eat it. Specially people who work for long hours and they don't have time to cook so they just eat fast food but 40000 human dies every year from junk food and people try to avoid it but some of them can't.
In Egypt fast food is more dangerous because they use the spices that Europe through in the sea and this is so bad for Egyptians health but it seems that we have an iron stomach .and I think we should stop eating junk food for our health to decrease the number of people who die because of junk food.
To conclude I would like to say that if people didn't stop eating junk food after 100 years people won't eat healthy food anymore and they will live less than we live now days maybe only 40 years and maybe only 30 and if we didn't stop now we will never stop thus we have dug our grave with our hands.
