The Story of Bottled Water, employs the Story of Stuff style to tell the story of manufactured demand—how you get Americans to buy more than half a billion bottles of water every week when it already flows from the tap. Over five minutes, the film explores the bottled water industrys attacks on tap water and its use of seductive, environmental-themed advertising to cover up the mountains of plastic waste it produces. The film concludes with a call to take back the tap, not only by making a personal commitment to avoid bottled water, but by supporting investments in clean, available tap water for all.

Why Corrosion Control of Reinforcement bars (Rebars) is necessary? Corrosion control of steel reinforcement is necessary to prevent damage and failure of concrete structures. Nearly 40% of failure of concrete structures is due to corrosion of embedded steel reinforcement There can be many causes for corrosion of reinforcement, but mostly it is related to the quality of concrete, environment, and quality of construction practices. So, the first step in corrosion control of rebar is to provide good quality of concrete through good construction practices. The quality of concrete materials, mixing, placing and compaction techniques and good workmanship can help control the rebar corrosion. Fig: Types of Cracks in Concrete due to Corrosion of Rebar Though quality control in concrete construction may reduce chances of corrosion, there are various methods by which the corrosion control of reinforcement bars can be achieved. Methods of Corrosion Control of Reinforcement in...
