Nowadays, one of the biggest problems human are facing with is water pollution. Water pollution is defined as the presence in groundwater of toxic chemicals and biological agents that exceed what is naturally found in the water and may pose a threat to human health and/or the environment. A lot of causes are responsible for this issue. And they lead to extremely bad consequences. I’d like to explain more in the following paragraphs.

Some typical causes of water pollution are Industrial waste, Sewage and waste water, Mining activities, Accidental Oil leakage, Burning of fossil fuels, Chemical fertilizers and pesticides, … These agents contribiute to water pollution.

And the consequences? Of course, it is human health! Human are likely to get into trouble with some diseases such as hepatitis by eating seafood that has been poisoned. Water pollution also brings about the death of aquatic (water) animals, Disruption of food-chains, Destruction of ecosystems.

In conclusion, water pollution is a alarming problem that needs to be solved as soon as possible. The sooner we solve it, the more healthy we are.

There is a tradition in Japan that people perform the Obon dance during the Obon festival. The orginal meaning of this festival is to honour their ancestors. The festival is celebrated in mid-August in many regions of Japan and mid-July in other regions. There are many different forms of Obon dance in different regions. The most typical form is circle dance. In order to perform it, people make a circle around a yagura, a high wooden stage; some dancers move clockwise, and some counter-clockwise. Obon dance is a beautiful tradition that needs to be preserved because it is one of the most important traditions. Lots of people come back to reunite with their families during the Obon festival. I really like this dance.
