1. Air pollution
Air pollution is a most serious problem of the current time all over the world especially in the large cities because of the huge level of industrialization. The release of such air pollutants in heavy concentrations such as smog, particulates, solid materials, etc are getting settled over the city, causing air pollution and health hazards to the people. Lots of dirty wastes produced by people on daily basis especially in the big cities polluting the whole atmospheric air to a great extent.
The release of gaseous pollutants from burning fuel of motor vehicles, industrial processes, burning of garbage, etc are contributing to the air pollution. Some natural pollutants like pollen, dust, soil particles, natural gases, etc are also the source of air pollution.
2. Natural disaster
Today, I’d like to tell you about a flood which hit my province, Nghe An, when I was 14 years old.
The flood came after a violent rainstorm. It had been predicted as the biggest flood in history so people had prepared a lot before the flood struck.
You know, at that time, the weather in Nghe An was terrible. It had rained for almost a month.
People had folded and rolled up their furniture, and electrical appliances and other belongings to higher places.
We had also brought outside possessions indoors or tied them down.
Shops had been opened all day and all night for people to buy essential things such as noodles, water or medicine.
When water in rivers and lakes rose up above the normal level and flowed into the land, electricity was cut.
My family and I worked hard to find bricks, stones, and sand bags in order to dam the water that flooded our house.
During the entire week of that event, we were not able to go out of the house.
All the roads were cut off and we did not have running water or phones. Some people had to climb up the roofs as the water from the river flooded their houses very quickly.
They had to sit on the roofs with their families and some of the things that they had been able to bring along until a rescue party came to help them.
They had to use boats instead of cars or walking.
After the flood, there was mud everywhere and water was all polluted. People were sick.
Many houses were damaged, castles were swept away and the prices of essential goods were much higher because of increasing demand.
People cleared up the debris. Volunteers came to help build up houses and clean up furniture.
It was such a long nightmare.
3, A way of communication in the future
Have you ever asked yourself what ways of communication you will be using in the future?
I strongly believe there will be huge changes in the way we communicate.
When we want to ask our friends to get some drinks, we often contact them by phone or social media.
However, in 20 years, super-smart phones, which can read your thoughts and automatically transfer them into text or voice messages, will be replacing those methods.
That will certainly be very amazing!
