Students watched  videos related to  global climatic change.Thay discussed about the pros and cons of technology. 

Increasing temperatures caused by climate change will make the water of the oceans expand; ice melting in the Antarctic and Greenland will also contribute to the sea level. Sea levels could rise by as much as 25 to 50 cm, by 2100. Greater sea levels will threaten the low-lying coastal areas such as the Netherlands and Bangladesh, millions of areas of land will be at danger from flooding; causing people to leave their homes. Low lying areas in cities will be hugely affected by the rising sea.

Changes in weather will affect many crops grown around world. Crops such as wheat and rice grow well in high temperatures, while plants such as maize and sugarcane prefer cooler climates. Changes in rainfall patterns will also affect how well plants and crops grow. The effect of a change in the weather on plant growth may lead to some countries not having enough food.
