Topic 2: Advantages of IC Card ( Smart Card)

Flexibility. They allow multiple applications to be stored in one card. There is no need, for example, to carry several cards. One card can simultaneously be an ID, a credit card, a stored-value cash card, and a repository of personal information such as telephone numbers or medical history. One card can access multiple transactions
Security.
Such a card can be easily replaced if lost. And, because a PIN number (or other form of security) must be used to access information, is totally useless to people other than its legal bearer. At the first attempt to use it illegally, the card would be deactivated by the card reader itself.
Smart cards can be electronic key rings, giving the bearer ability to access information and physical places without need for online connections.
Portability
Increasing data storage capacity: The amount of information can be stored in smart cards is much greater compared to magnetic stripe cards. Some of them can also be reprogrammed to add, delete or rearrange data.
Reliability that is virtually unaffected by electrical and magnetic fields.
Longer life: They are much more durable. They are reusable.

Topic 3: What can we do to protect the environment?

Don’t smoke. (reduce air pollution)
Car fumes produce carbon dioxide and nitrogen oxide - so try to cut down on car journeys if possible. Use a bike or walk - it's good exercise for you too!
Sort out your rubbish. Recycle as much of your waste as you can. Methane, the most effective 'greenhouse gas', is released into the air as the rubbish in landfill sites rots.Try to avoid buying plastic. It's hard to recycle. One way to cut down on plastic is to refuse to use carrier bags offered by supermarkets and use strong, long lasting shopping bags instead, or re-use plastic bags over and over again, until they wear out.
Try to buy 'environmentally-friendly' products.
Use recycled paper to help save trees.
Don't buy over-packed goods. Many things we buy have unnecessary amounts of plastic and paper around them.
Use mobile phones, computers, microwave stoves properly. ( reduce electromagnetic pollution )
Take your old clothes to charity shops. Some are sold, others are returned to textile mills for recycling.
Use less energy by switching off lights when rooms are not in use, not wasting hot water, not overheating rooms and not boiling more water than necessary when making a cup of tea!
If you spot pollution, such as oil on the beach, report it to the local council. If you suspect a stream is polluted, report it to the local Environmental Health Officer
If you use chlorine-based bleach or detergents containing phosphates you are contributing to water pollution.
Don't waste electricity. Electricity is produced by burning coal, oil and gas and this action gives off carbon dioxide.

Topic 4: Advantages and Disadvantages of Renewable Energy

Advantages

Renewable it is therefore sustainable and so will never run out.
Renewable energy facilities generally require less maintenance than traditional generators. Their fuel being derived from natural and available resources reduces the costs of operation.
Renewable energy produces little or no waste products such as carbon dioxide or other chemical pollutants, so has minimal impact on the environment.
Renewable energy projects can also bring economic benefits to many regional areas, as most projects are located away from large urban centres and suburbs of the capital cities. These economic benefits may be from the increased use of local services as well as tourism.

Disadvantages

1. It is difficult to generate the quantities of electricity that are as large as those produced by traditional fossil fuel generators. This may mean that we need to reduce the amount of energy we use or simply build more energy facilities. It also indicates that the best solution to our energy problems may be to have a balance of many different power sources.

2. The reliability of supply.

Renewable energy often relies on the weather for its source of power. Hydro generators need rain to fill dams to supply flowing water. Wind turbines need wind to turn the blades, and solar collectors need clear skies and sunshine to collect heat and make electricity. When these resources are unavailable so is the capacity to make energy from them. This can be unpredictable and inconsistent. The current cost of renewable energy technology is also far in excess of traditional fossil fuel generation. This is because it is a new technology and as such has extremely large capital cost.
