In my opinion, tap water is safer than bottled water. A non profit public health advocacy group based in Washington D.C., the environmental working group tested 10 brands of bottled water and found 38 pollutants in them. These included disinfection byproducts, arsenic, fertilizer residue, plasticizers and pharmaceuticals. Low levels of these may be found in tap water. But the scenarios are completely different because with tap water they have to tell you what in it and with bottled water they do not.("New Study Finds Fault With Some Bottled Waters; Tap Water a Better Bet.")

You should consume filtered tap water instead of bottled water. You are getting the same thing either way, water is water. Except that with tap water you know exactly what you are getting and with a bottle it is questionable.("New Study Finds Fault With Some Bottled Waters; Tap Water a Better Bet.") Bottled water also costs fifteen times more and the bottles are just piling up in land fills. In addition to that, bottled water consumes 17 million barrels of oil every year in order to produce the bottles. If we just eliminated bottled water then we wouldn't be so oil hungry. It takes three gallons of water to produce one gallon of bottled water.("What Is The Real Cost Of Bottled Water?" ) Tap water costs less than one cent per gallon. Gasoline costs two cents an ounce. Bottled water is five cents an ounce.(BaskindMon ) Somehow that just seems so wrong to me.

The Amazing Cockroach!

The American Cockroach is about one and a half inches. They are reddish brown. Roach mouths work vertically, not horizontally like ours. They have six hairy legs and eighteen knees. All American roaches, like most Americans, were immigrants. There is no where on the planet that doesn't have local roaches. In colder climates, however, they survive by shaking up with humans. Roaches can go for a month without eating. They identify other friend and family roaches by their distinctive odor.("Roach Facts.")

A cockroach can hold their breath for 40 minutes. They spend 75 percent of their time just resting. It is possible for a female roach to mate once and then spend the remainder of her life pregnant. Their hearts are nothing but a simple tube with valves that pumps blood forwards and backwards. If the heart stops moving it does not harm the creature. A cockroach can live one week without a head. Even then they only die from lack of water because they have no mouth. Not because they have no head. So it stands to reason that if they had an alternative way to drink water, they could go on forever without a head.("Yucky: Roach Facts.") I doubt that human's will affect the survival of the roach. They are real survivors. Some experts believe that they could survive the fallout of a nuclear war. They also reproduce quickly so I don't think a shoe is any threat to them in the long run.

Urban Sprawl

Urban sprawl is when a city continues to spread out beyond what it can support. It is the product of affordable land, cars, somewhat inexpensive gasoline, and absent minded urban planning. The lack of mass transportation forces people to drive everywhere, which causes them to emit even more greenhouse gasses than is necessary. Sprawl destroys cropland, wetlands, and forest. On the flip side of the discussion, it causes the economic deaths of many cities as well when people and businesses move further out. What is scariest of all is that while urban populations only occupy 2% of the earth's land area, they consume 75% of her resources.
Smart growth is an alternative method for dealing with urban sprawl in an environmentally sustainable way. It uses zoning laws and other tools to discourage sprawl, reduce traffic, protect important lands and waterways, and develop neighborhoods. A city that takes it one step further to become even more environmentally sustainable is known as an ecocity or a green city. They emphasize the three principles of sustainability which are solar energy, chemical cycling, and biodiversity.
What a city should do to correct this problem is to use these five environmentally-sustainable methods. The city would promote urban gardens and farmer's markets. It would make use of locally available renewable energy resources. They would redesign the city for people instead of cars. The city would have to prevent pollution and reduce waste. At least 60% of municipal solid waste would have to be recycled, reused, or composted.
