·Water is the most important substance in our evolution and our daily lives. Without water, life as we know it would not have been possible. In typical usage, water refers only to its liquid form or state, but the substance also has a solid state, ice, and a gaseous state, water vapour.
·Clean, fresh water is essential to human and other life. However, in many parts of the world, it is in short supply. Consequently it is important save water because if you haven't got water you haven't got life.
2) Climate is changing, and we are the ones to blame. Global warning, violent weather, rising sea-levels, melting glaciers... they are all signs of this change. Besides, climate change is affecting our daily lives.
My life is not the same as it was five years ago. Now I'm conscious that I have to change my lifestyle if I want to protect our planet. That's why I always turn off my home appliances, I don't waste energy unnecessary and I try to save water. What's more, I decided use my bike to go to school, instead of the car.
To sum up, I believe that people must be concerned about climate change. It's time to modify our way of life and to try to undo the huge damage we have done to the environment.
Nowadays, many people have mobile phones. They are becoming a necessary and integral part of everyone's life, from housewives to businesspeople.
There are many advantages to having a mobile phone. As long as your phone is connected, anyone can reach you anywhere and at any time. In addition, mobile phones are quite handly in emergency situations such as when your car breaks down or you have to call the police in a hurry...
On the other hand, there are some disadvantages to mobile phones. Talking on the phone in cars can be very dangerous. Moreover, scientific studies have shown that excessive use of mobile phones can cause health problems...
I think that in the long run, the disadvantages of mobile phones are more convincing than advantages, since they can cause health problems and over-dependence on devices. That's why we should think twice before we buy a mobile phone.
