Two leading church-based aid organisations have called for action on climate change and a change in lifestyles to ensure that people do not go hungry.
The theme of the 40th anniversary ecumenical campaign by the Swiss Catholic Lenten Fund and the Protestant Bread for All, announced on Monday, is "a healthy climate to guarantee daily bread".
According to a Lenten Fund statement, around 925 million people suffer from hunger around the world, with climate change – in the form of floods, drought - increasingly having an impact on food supply.
The non-governmental organisations are calling on the Swiss government to increase its efforts in lowering global carbon dioxide emissions and to help developing countries. The population could reconsider its consumption and lifestyle needs, they added.
The two agencies are setting an example by offering a carbon dioxide calculator and guidelines for saving energy to parishes.
