MADURAI: In India, 20 acres of forest cover is reduced every minute. By 2010, most forests might not exist, leading to acid rains and other environmental disasters, R. Vasudevan, Dean, Thiagarajar College of Engineering (TCE), said here on Tuesday.

Industrialisation, deforestation and improper waste disposal were some of the major causes for climatic changes, he said while addressing a seminar on ‘Global warming and renewable energy sources’ organised by TCE and Tamil Nadu Energy Development Agency.

About 60 students from seven educational institutions participated.

“India has 30 per cent of the world’s organic waste, which can replace an equal amount of fossil fuels.

“The latter does not pollute the atmosphere,” he said.

R.V. Jebarajasekar, Scientific Officer, Madurai Kamaraj University, said that solar thermal energy was most user-friendly, eco-friendly and performed satisfactorily.

New Delhi, Mumbai and Kolkata were among the most polluted cities in the world, he said.

P. Ravikumar, Dean, Periyar Maniammai College of Technology for Women, Thanjavur, delivered a lecture on biomass gasification.

K. Srithar, A. Valan Arasu and V. Saravanan, all professors of TCE, spoke.
