It has to be a 10-15 minutes long and 3-5 pages. We have to find a way to improve it without damaging its commercial cost. We have to find a way to make it better economically as well as to everyone else. We also have to say how it has impacted the environment. We were thinking about hydrogen peroxide but its just too confusing to do and we can't really find information over it that much....so we're having second thoughts your advice will be very useful and be taken into consideration!!
