Density is also an advantage as it can generate a lot of energy.This is good for the microbeads as it will create a lot of product much quicker (Green garage,2015).As these advantages speed up the process of manufacturing microbeads,petroleum also causes many disadvantages, especially to the environment(Adams,2014).The disadvantages are the fact that petroleum contributes to environmental pollution as it needs to be transported over oceans,in which can cause an oil spill(Greengarage,2015). This causes damage to water ways,marine life and can cause financial problems to those companies who lose billions of dollars due to this transportation problem(Greengarage 2015).The production of petroleum leads into the manufacturing of toxic and harmful materials,just like polyethene(Thefactsabout.co.uk,2017).There are many natural alternatives for the use of microbeads in beauty products(Biome Team,2016).The alternatives include powders such as rice powder,argon shell,oatmeal and wheatgrass(Biome Team,2016).All these natural products exfoliate your skin just as the microbeads would.As these resources are natural they do not send off toxic chemicals into our waterways.They are also compressed powders which means they are biodegradable and will not leave a long-term effect on our environment (Biome Team,2016).Polyethene is a versatile synthetic,organic substance made from ethylene. Ethylene(C2H4)is a hydrocarbon which is produced by the cracking of ethane (Encyclopedia Britannica,2017).This is a major component of natural gas;in this case,it can be produced by petroleum(Encyclopedia Britannica, 2017).When heated,there is a catalyst that is present this forms a strong double bond between to carbon atoms(Science and Earth,2017)There is a strong bond which is very difficult for any natural resource to break this bond.As polyethene is a man-made product is it very hard for any natural resource to decompose of these materials when released out into the environment(Ms Simmons,2017).Polyethene microbeads are very small pieces of plastic which are released into our water ways once an individual uses a beauty product containing these small beads(Anon,2017).The main problem to using polyethene is that our marine life are mistaking microbeads for their food(The story of stuff project,2017).Unfortunately,this leaves the animal with circulatory and possible digestive blockages,leaving the animal very ill(Anon,2017).As we see on the news,a large number of turtles die or become very ill with malnutrition and starvation due to the littering and consumption of plastic bags(Beatthemicrobead.org,2017).In this case plastic bags are equivalent to the miniature microbeads,they leave fish and other marine life very ill(Beatthemicrobead.org,2017)This is a very d
