I read in a respectable scientific journal that global warming is already happening. Satellite images have shown that climate change is even reducing the legendary snow on the top of Mount Kilimanjaro. Since 2000, observations of the significant effect of rising temperatures have started to mount up. Even the American business community has stopped trying to give a false impression that everything it’s all right.

Speaking: Exercise 9 page 19
Discuss changes in your environment. Use the present perfect simple and continuous.
The first warning about global warming was in 1950. Since then, change climate has been evoluating dramatically faster then that scientists predicted. Many species risk loosing their habitat (eg : polar bears) and the people had realised that the future of our planet is compromised.
In the south east of Romania were I have been living, people complain about the seasons’ characteristics changing. The summer become hut and droughty and that had a significant bad effect on agriculture. Our grandparents told that in winter the layer of snow was huge. Today is rarely snowing in winter. Latest years, our region has received more and more alarms. The unexpected hard rain has drowned farmlands and inhabitants' houses. All these changes have been decreasing people’s standards life, because of their indirect effects. The drought affects the agriculture, so less foods for domestic animals and for inhabitants who become more susceptible to disease.
About the global environmental problems like climate change, pollution, forest fires, oil spills, hole in the ozone layer, each of us has already heard from the media. But people are continuing to destroy their own house, their planet. The only hope is that “every single one of us makes a difference every day” (Jane Goodall). The difference is to make a choice, to adopt the behaviour and to act in a way that does not harm our planet.
