1. Write about a type of pollution in your area số 1

Nowadays, pollution is a popular term with everyone in the world and air pollution is one type of pollution. The definition of air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. There are some main reasons which cause air contamination such as burning of fossil fuels, agricultural activities, exhaust from factories and industries, mining operations, and indoor air pollution. Air pollution always has bad effects on our life. Harmful gases, dust, and smoke enter into the atmosphere and make it difficult for plants, animals and humans to survive. We also can see some examples of the result of air contamination which occurs around us as global warming, acid rain, and depletion of ozone layer. The effects of air pollution are alarming, so governments over the world should have suitable policies of protecting the environment, especially air quality to create a clean world for our generation in the future.

Hello everyone, today I'd like to tell you some information about types and sources of energy. Energy is classified into two main groups: renewable and non-renewable.

The energy generated from natural sources such as the sun, wind, rain, and tides is called renewable energy. They are plentiful and can be generated again and again. They also have low carbon emissions so they are considered green and environment-friendly. Moreover, using renewable energy can reduce your electricity bills. Unfortunately, solar energy can be only used during the daytime but not during night or the rainy season. Geothermal energy also can bring toxic chemicals beneath the earth's surface to the top and can create environmental changes.

Non-renewable energy is the energy taken from other sources that are available on earth.They are limited and will run out in the future. They can't be re-generated in a short time.Fossil fuels - natural gas, oil and coal - are examples of them. They are cheap and easy to use. However, when burnt, they release toxic gases in the air so they cause serious environmental changes such as global warming. And the important thing is that non-renewable sources will expire someday. 2. 1. Use public mode of transportation

Encourage people to use more and more public modes of transportation to reduce pollution. Also, try to make use of carpooling. If you and your colleagues come from the same locality and have same timings you can explore this option to save energy and money.

2. Conserve energy

Switch off fans and lights when you are going out. A large number of fossil fuels are burnt to produce electricity. You can save the environment from degradation by reducing the number of fossil fuels to be burned.

3. Understand the concept of Reduce, Reuse and Recycle

Do not throw away items that are of no use to you. In-fact reuse them for some other purpose. For e.g. you can use old jars to store cereals or pulses.

4. Emphasis on clean energy resources

Clean energy technologies like solar, wind and geothermal are on high these days. Governments of various countries have been providing grants to consumers who are interested in installing solar panels for their home. This will go a long way to curb air pollution.

5. Use energy efficient devices

CFL lights consume less electricity as against their counterparts. They live longer, consume less electricity, lower electricity bills and also help you to reduce pollution by consuming less energy.

Several attempts are being made worldwide on a personal, industrial and governmental levels to curb the intensity at which air pollution is rising and regain a balance as far as the proportions of the foundation gases are concerned. This is a direct attempt at slacking Global warming. We are seeing a series of innovations and experiments aimed at alternate and unconventional options to reduce pollutants. Air pollution is one of the larger mirrors of man’s follies, and a challenge we need to overcome to see a tomorrow.

TYPE OF NATURAL DISATER: Flood

WAYS TO PREPARE:

• – Check for local flood warnings if your area is at risk: look online or call Floodline.
• – Tune in to the local radio or television news for updates. Alert your neighbours, particularly elderly or vulnerable people.
• – Prepare an emergency kit, including emergency numbers, insurance policy, first aid kit, torch and water.
• – Use our home emergency contacts sheet so you have the numbers you need to hand, even if you lose power.
• – Have a list of irreplaceable items to keep safe and put important personal documents into a sealed bag.
• – Pack essential items you will need if evacuated – medication, clothing, toiletries and items for children.
• – Purchase unfilled sandbags and sand from builders’ merchants. Remember that, if there is a flood, demand may exceed supply – as people will rush to buy them.
• – Empty freezers and refrigerators, leaving doors open.
• – If you can, move any vehicles to higher levels.
• – If you have time, take photographs before you leave. This may help later with insurance claims.
• – Turn off the mains power and water, and take mobile phones and chargers with you. Put sandbags in toilet bowls to prevent sewage back-flow.
• – Shut windows, lock doors – and don’t forget to take your pets.
