The need to fight climate change on planet Earth due to global warning was underlined at a seminar held here to mark World Environment Day.

Renowned scientist Dr Raghunandan of the Delhi Science Forum cautioned that if the global warming was not controlled, it would destroy the planet Earth in next 100 years. It had already started showing its harmful effects on weather cycle, crops, vegetation and water resources and receding glaciers and rise in sea level were some of the indications that indicated towards the impending doom.

The director, CSSRI, Dr Gurbachan Singh, said increase in emission of greenhouse gases, depleting forests and over exploitation of natural resources was responsible for climate change and collective and concerted efforts were required to meet the challenge.

The seminar was organised by the Haryana Literacy Samiti and the Haryana Vigyan Samiti.

The National Dairy Research Institute (NDRI) observed the day by launching a campaign to plant “neem” saplings to preserve green cover.

Principal scientist and registrar Rameshwar Singh said the drive would continue for few weeks and 3,000 saplings would be planted.
