Consumismo dar uma idea básica de querer uma coisa exageradamente , e sem querer saber se isso pode ser prejudicial ao ambiente em que vivemos ou até mesmo prejudicial a nossa saúde !
Vi num site que ocorrem várias discursões e palestras sobre esse assunto em todo mundo , quer dizer qui isso não é apenas um problema em nosso país e sim ocorre em todo mundo , oque mais influência a isso : um exemplo , propagandas de televisão que nos induz a querer um objeto mais e mais , nos induz a um consumo desnecessário , provocando um aumento no fênomeno capitalista da nossa sociedade .
Existe o consumo e o consumismo , a diferença de um para o outro é que : no consumo as pessoas adiquirem só aquilo qui é necessário para se viver , no consumismo as pessoas querem ter mais do que pode , até se individam para ter aquilo qui lhe é desejado .
Vários casos o consumismo vira o mesmo qui uma doença , e a pessoa deve se tratar , pode trazer maiores danos a pessoa no futuro !

Paper, Plastic, or Something Better?

The next time the clerk at your favorite grocery store asks whether you prefer “paper or plastic” for your purchases, consider giving the truly eco-friendly response and saying, “neither.”
Plastic bags end up as litter that fouls the landscape, and kill thousands of marine mammals every year that mistake the floating bags for food. Plastic bags that get buried in landfills may take up to 1,000 years to break down, and in the process they separate into smaller and smaller toxic particles that contaminate soil and water. Furthermore, the production of plastic bags consume millions of gallons of oil that could be used for fuel and heating.
Is Paper Better Than Plastic?
Paper bags, which many people consider a better alternative to plastic bags, carry their own set of environmental problems. For example, according to the American Forest and Paper Association, in 1999 the U.S. alone used 10 billion paper grocery bags, which adds up to a lot of trees.
Reusable Bags Are a Better Option
But if you decline both paper and plastic bags, then how do you get your groceries home? The answer, according to many environmentalists, is high-quality reusable shopping bags made of materials that don’t harm the environment during production and don’t need to be discarded after each use. [You can find a good selection of high-quality reusable bags online at In addition, many organic grocery stores and consumer co-operatives carry reusable shopping bags.]
Experts estimate that 500 billion to 1 trillion plastic bags are consumed and discarded annually worldwide—more than a million per minute.
Here are a few facts about plastic bags to help demonstrate the value of reusable bags—to consumers and the environment:
• Plastic bags aren’t biodegradable. They actually go through a process called photodegradation—breaking down into smaller and smaller toxic particles that contaminate both soil and water, and end up entering the food chain when animals accidentally ingest them.
• According to the Environmental Protection Agency, more than 380 billion plastic bags are used in the United States every year. Of those, approximately 100 billion are plastic shopping bags, which cost retailers about $4 billion annually.
• According to various estimates, Taiwan consumes 20 billion plastic bags annually (900 per person), Japan consumes 300 billion bags each year (300 per person), and Australia consumes 6.9 billion plastic bags annually (326 per person).
• Hundreds of thousands of whales, dolphins, sea turtles and other marine mammals die every year after eating discarded plastic bags they mistake for food.
• Discarded plastic bags have become so common in Africa they have spawned a cottage industry. People there collect the bags and use them to weave hats, bags and other goods. According to the BBC, one such group routinely collects 30,000 bags every month.
• Plastic bags as litter have even become commonplace in Antarctica and other remote areas. According to David Barnes, a marine scientist with the British Antarctic Survey, plastic bags have gone from being rare in the late 1980s and early 1990s to being almost everywhere in Antarctica.
Some governments have recognized the severity of the problem and are taking action to help combat it.
Strategic Taxes Can Cut Plastic Bag Use
In 2001, for example, Ireland was using 1.2 billion plastic bags annually, about 316 per person. In 2002, the Irish government imposed a plastic bag consumption tax (called a PlasTax), which has reduced consumption by 90 percent. The tax of $.15 per bag is paid by consumers when they check out at the store. Besides cutting back on litter, Ireland’s tax has saved approximately 18 million liters of oil. Several other governments around the world are now considering a similar tax on plastic bags.
Governments Use the Law to Limit Plastic Bags
More recently, Japan passed a law that empowers the government to issue warnings to merchants that overuse plastic bags and don’t do enough to “reduce, reuse or recycle.” In Japanese culture, it is common for stores to wrap each item in its own bag, which the Japanese consider a matter of both good hygiene and respect or politeness.
Companies Making Tough Choices
Meanwhile, some eco-friendly companies—such as Toronto’s Mountain Equipment Co-op—are voluntarily exploring ethical alternatives to plastic bags, turning to biodegradable bags made from corn. The corn-based bags cost several times more than plastic bags, but are produced using much less energy and will break down in landfills or composters in four to 12 weeks.


Global warming on plastic bottles
Global warming on plastic bottles is a real concern. The number of plastic bottles that we use in the United States each year is amazing. Considering the cost of bottles of water compared to the cost of tap water, we spend 10,000 times the amount on water bottles than we would if we just used tap water. Tap water is just as safe as bottled water and many times bottled water is also tap water. In the United States, the quality of tap water surpasses that which is required for bottled water. Essentially tap water is cleaner and safer than bottled water at least in the United States.
Reducing Global Warming
To reduce global warming on plastic bottles it is suggested to use tap water at home and to bottle your own water. You can take your tap water with you when you are on the goy using a reusable water container you can reduce the number of water bottles that end up in landfills. There are 60 million water bottles thrown away each day and only 10 percent of those bottles end up being recycled. That means that 90 percent of those 60 million bottles end up in landfills taking more than 1,000 years to breakdown and decompose. This is one of the largest problems with global warming on plastic bottles. With than many plastic bottles just ending up in a dump instead of being recycled and used in other products we are polluting our land and water supplies with this kind of waste. Even if every single bottle was recycled this is not the only problem with global warming on plastic bottles.
Oil Consumption and Plastic Bottles
You also so should consider the amount of oil that it takes to produce these plastic bottles. Plastic bottles are created from oil. To make the 50 billion plastic PET bottles each year it takes 1 and a half million bottles of oil. That is enough oil to fuel 1 million cars for an entire year. That is only the oil that goes into the bottles. It does not account for the energy it takes to run the manufacturing plants and the bottling company or to clean and prepare the water for bottling or for the shipping of the water once it is bottled.
Global warming on plastic bottles should also account for the amount of Carbon Dioxide that is released into the atmosphere. In fact, for every of PET plastic bottles three tons of carbon dioxide is created. This is 0.1 percent of greenhouse gas emissions each year or 2.5 million tons of carbon dioxide.
To reduce the effects of global warming on plastic bottles than we should consider using reusable bottles either from plastic or stainless steel canteens. The quality of water in the United States is high but if you are traveling outside of the United States than you should consider using plastic water bottles. By using reusable plastic bottles or stainless steel bottles, we can reduce the number of plastic bottles in the landfills. We can also reduce the amount of oil we use and the carbon dioxide released into the atmosphere. We will be saving ourselves money while saving the planet.

Reciclagem e coleta seletiva

Reciclagem é um conjunto que aproveita os detritos e reutilizam no ciclo de produção que saíram. Isto é bom porque, ainda reaproveitam os lixos e reciclam, e ainda não jogam fora.
Para reciclar é muito fácil, ainda mais com a ajuda das populações que podem contribuir jogando os lixos nas lixeiras de acordo com a divisão de todos os recursos.
Coleta seletiva é um sistema que recolhe os materiais recicláveis,como papeis, plásticos,vidros, metais e orgânicos, separados na fonte geradora.

Embaixo, são os tempos de decomposição do lixo na natureza:

Ato publico ( Coleta Seletiva )

Texto sobre o ato publico (coleta seletiva) debatido no Colégio intelecto.

O Colégio intelecto fez uma passeata pelas ruas do centro da cidade de Feira, sobre o ato publico – a coleta seletiva.
Em Feira de Santana, existem poucas coletas seletivas, isto é ruim para o meio ambiente, pois as populações não vão poder onde jogar os lixos, e com isso faz com que algumas pessoas joguem os lixos nas ruas, ou seja, aquelas pessoas que não tem noção do mal que estão fazendo com isso.
E na verdade em que consiste a coleta seletiva?
Coleta seletiva é o termo utilizado para recolher materiais que são possíveis para serem reciclados, previamente separados na fonte geradora. Os materiais recicláveis, os diversos tipos de papéis, plásticos, metais e vidros.

A separação dos lixos evita a contaminação dos materiais reaproveitáveis, aumentando o valor agregado destes e diminuindo os custos de reciclagem.

Os maiores beneficiados por esse sistema são o meio ambiente e a saúde da população.
A reciclagem de papéis, vidros, plásticos e metais, que representam 40% do lixo domestico, pois reduz a utilização dos aterros sanitários, prolongando sua vida útil.

Os apectos da Globalização .

Com o avanço da tecnologia , o mundo se tornou mais globalizado , ou seja , o mundo de novos avanços . Com isso o mundo está se acabando , pois , os automóveis poluem muito o ambiente , não só o automóvel como industrias , entre mais .
Creio qui venha ocorrendo até os tempos de hoje , a tal da Globalização . Com a queda dos transportes maritímos e as relações políticas européias . Um período de grande aumento no fluxo de trabalho entre países e continentes resultou no aumento do capital .
A Globalização afetou todas as partes da sociedade ,mexe com os setores da economia , cultura , política principalmente a de comunicação , qui acaba sendo impulsionadanos países de todo o Mundo no final do século XX e início no século XXI
Mas , qual o significado de Globalização ?
Globalização , é um fenômeno capitalista qui começou a partir da Revolução Industrial , mas foi passado despercebido até a 2° Guerra Mundial .

A Globalização, por ser um fenómeno espontáneo decorrente da evolução do mercado.É dos processos que integra a cultura , política ,econômia , social. A 'aldeia global' que permite maiores mercados para países ditos desenvolvidos .
A globalização atinge nos setores de comunicação, a qualidade de vida , efeitos nas indústrias e serviços .
Seus efeitos na globalização , vai provocando os maléficios apesar das promesas cada vez aumenta mais , o almento acelerado do desemprego , a criminalidade pela atividade humana, principalmente em países humildes .
