Patna, March 15: Students used their brush and canvas to express concern over the changing condition of the climate at a poster exhibition on “biodiversity conservation”.

The exhibition was organised by AN College department of environmental science, in collaboration with the department of chemistry and National Service Scheme Unit on the college premises today.

“We cannot command nature. We have to obey her,” said Pintu Kumar Singh, a first year postgraduate student of the environmental science department. Singh had taken part in the two-day-long awareness programme at the college, sponsored by the National Environment Awareness Campaign of the Union ministry of environment.

Singh’s poster depicted a mother pigeon protecting her young ones by sheltering them under her wings. The caption read: “Don’t kill us. Our conservation is your protection.”

“Birds and other creatures are getting extinct because of climatic changes that are triggered by human beings. In my poster, I have captured the same. I have shown poisonous exhaust fumes of factories and how a pigeon is trying to protect her young ones from these fumes,” said Singh, explaining his poster.

His friend Ranjit Kumar Singh helped him conceptualise his poster, he added.

Environmental science student Sapna Singh used basic pencil sketching to depict a terrified tiger. Her caption: “I am terrified, please save me.” Sapna added the only way to protect the environment was to reuse and recycle for the present and save for the future.

Her classmate Ranjeet, who also took part in the exhibition, said: “We should not be wild to our wildlife.” Their classmate, Afsana Mumtaz also depicted endangered species — pandas and butterflies — in her poster. The panda in the poster has been depicted holding a placard that read: “There are too many people but too few human beings.”

AN College biotechnology department head Chandravati, one of the judges today, said: “The poster reflect the seriousness of the subject. The students have been able to depict the problems and suggest proper solutions for them. What took me by surprise was how imaginative the students are in depicting their thoughts.

“Colours are very important in posters. Students have used it to the best of their ability,” added Chandravati.

As a part of the programme, 50 medicinal saplings were also planted in the garden of the college. Principal Haridwar Singh, environmental science head Bihari Singh and teacher Purnima Shekhar Singh oversaw the planting of the saplings.

A theme-based quiz competition was also held, in which 55 students took part.
