Forestry increases the CO2 levels in the atmosphere . Because of this greenhouse gases are trapped in the atmosphere . Because of this the temperature is increased and the ice caps melt on the south and north pole . Short term Canada will benefit because of the increase of tempreture alot of people will be willing to move to the North because the Cold was always a push factor when it came to the North . But in the long term some parts of Canada will be under water which means people will loose their homes . By reducing tree cutting and managing it better we can reduce the CO2 submissions into the atmosphere reducing the effects . Personally I think we need to use wood appropriately . And if we don't we will become a planet like Venus . What do you think the world will look like in 1000 years ?
