This day CNN documentary films about the condition of the environment were showed and then current ecological problems were discussed at the English Speaking Club. Besides general questions, the participants discussed personal attitude to the present environmental conditions and what we can really change in it. Tomsk AC representatives told the audience about the history of the International Earth Day which appeared in 19th century at J. Sterling Morton’s initiative.

In 1970 this date was announced the International Earth Day when more than 20 million people in different countries took part in various ecological meetings and events. This year is the 40th anniversary of the Earth Day.
