There are many disadvantages to hard engineering that can effect not only the environment but people. The main disadvantages to hard engineering are that for one they are very aesthetically displeasing to some people and can take up a vast amount of room. Two, they are incredibly expensive for the amount that is usually used. Another problem is that if a sea wall breaks during a storm then the effects of that storm will seem a lot worse just like in river’s where if a levee breaks during a flood the effects are a lot worse. Another thing with hard engineering, going back to the costs is that not all of the countries in the world can afford to have hard engineering management strategies.
And although they offer financial and technical support, there are still problems on the Northern Beaches coastline. The erosion on Collaroy Beach is one of the worst cases in NSW, and without efficient action the problem will only get worse. In 2002 the Warringah council proposed to build a seawall on the beach. This was met with much criticism from the community, mainly due to the fact that a seawall would destroy the beaches natural beauty, something that no one wants to see. The designs for the sea wall cost roughly $100,000, and to build the wall would cost upwards of $11,000,000, of which 40% would be paid by the homeowners of Collaroy.
One con is that there will be many jobs at the mine, but just not nearly as many jobs that Bristol Bay employs in the salmon industry. Another, and possibly the biggest, disadvantage of building the Pebble Mine is the negative effect on the environment in Bristol Bay. Although the company managing this says that there will be a bad affect on the environment, history tells us otherwise. We can look at the Mount Polley gold mine disaster. In this environmental disaster, 10 cubic meters of water and 4.5 million cubic meters of potentially toxic slurry were spilled into virtually untouched forest, lakes and rivers.
During this time public law enforcement officials were having a great deal of trouble maintaining a secure-safe level of order and peace throughout most of the communities because of the increasing crime rates. Public law enforcements inability to protect and serve brought a great deal of negative attention and scrutiny upon most police departments. In return, this labeled law enforcement as an ineffective-inadequate means of protection. The failure of the police was the leading factor that gave Pinkerton the ideology to establish a private security business that would be capable of handling certain situations the public law enforcement previously had failed. In 1850, Pinkerton founded the Pinkerton National Detective Agency and contracted with a variety of businesses and employed a group of individuals who were assigned to work the night shift as night watchmen to protect these businesses.
The mountain pine beetle epidemic is causing environmental and social impacts to much of British Columbia. Our forests are very important and will no longer be able to maintain their role if changes are not made. The devastation has had a sweeping impact on B.C.’s ecological, and economical well-being. Additionally, recent studies are drawing attention to the carbon-emitting properties of the dead forests, which is a global concern. A popular misconception developed that the current provincial mountain pine beetle epidemic began in Tweedsmuir Provincial Park.
Nicholas Bloom, Author of Public Housing that Worked, acknowledges the skepticism of most Americans in saying,“Across the country public housing projects are being demolished at a record pace largely because most Americans believe that public housing has no chance of succeeding.” So why is public housing failing? And what will be done before thousands more Americans are left homeless. Public housing has created reliance on the government, unsafe living conditions, and large concentrations of poverty. Everyday events and common occurrences inside public housing would shock many, due to the high volume of violence. Also shocking is the high prevalence of health issues.
The streets were over populated and that is not good for the environment. Industrial agriculture was the reason why people in the movie didn’t have any running water. Also due to industrial agriculture it was hard to keep electric, Sol had to peddle the bike to keep the electric going (Solvent). In Solvent Green the people had hot temperatures and humidity caused by industrial agriculture. The whole environment changes all because of one simple thing that gets out of hand: industrial agriculture.
Fracking is inherently risky, there is extensive evidence to suggest that fracking can contaminate groundwater and that it causes significant air pollution. For the first time in history, smog has become a major issue in many rural communities in the US, with some villages in Wyoming experiencing worse smog than downtown Los Angeles and an increase in lung cancer cases of over 500%. Since 2005, 1.2 trillion litres has been wasted in the fracking process creating toxic waste which cannot be recycled and must be disposed of very carefully to avoid danger to humans and the environment. In addition, one in six deep injection wells examined have an integrity violation leading to the leaking of toxic waste into the environment – more than 17,000 violations in the US alone. Such is the desperation for energy in the US, fracking has had to be made exempt from parts of at least seven major national statutes, including the Clean Air Act, Clean Water Act and Safe Drinking Water Act in order for it to be made legal.
However, time has taken its toll on these aging technologies, and along with the roads they are falling apart. Our power plants are old, un-efficient, and in many cases, toxic. The power plants however, are not the only problem in the electrical crisis. The power polls are aging, and so are the transformers. With deforestation forcing many insects and animals out of their natural habitat, these rouge, unprotected wooden polls are a convenient new home.
Environment problem is a biggest problem that exist all countries around the world. Many countries, the environment are being polluted. Some countries haven’t found the solution to solve the environment problem yet. Like in Cambodia, the environment is being made worse day by day. Deforestation is the one of environment problems in Cambodia.
