I have witnessed people's views of religious tolerance being transformed while standing in a mosque in Central Asia, where, in 1881, Mennonites were invited to worship. In the same location, 126 years later, we were again invited by a local imam to sing a hymn and to pray.Being stewards of God's creation, we should take seriously the environmental issues of travel. There are ways today to offset carbon emissions from travel, and to make as small an environmental footprint as possible. There are even "Mennonite options" for carbon offsets being developed by Mennonite Economic Development Associates.Although we do need to minimize our environmental footprint, it is wrong to focus only on the negatives of travel without promoting the positives. The discussions and questions on travel should centre on "how", not "if" we are going to travel.
