There are many ways to spend money on the Internet - music downloads, poker games, bidding on a zombie attack survival kit on eBay.
You can also help reforest the Battlefords River Valley by purchasing carbon credits online at www.carboncreditcanada.ca.
The province's first carbon offset program was launched in February by the Association of Saskatchewan Urban Parks and Conservation Agencies (ASUPCA), a non-profit organization comprising the City of North Battleford and six other cities, with each highlighting a local cause.
The website features a carbon calculator based on the estimate that eight trees or 34 native shrubs are needed to sequester one tonne of carbon, valued at $50, in order to put a dollar value on the carbon footprint caused by travel, leisure activities and running a household.
For example, driving an SUV from North Battleford to Saskatoon emits 0.0474 tonnes of carbon, which can be offset by a $2.37 donation. Flying from Edmonton to Honolulu and spending three nights in a hotel adds up to a donation of $32.84.
"I'm hoping everyone will appease their inner dirtbag," said Keith Anderson, acting director of Parks and Recreation for the City of North Battleford.
"If people go to Saskatoon or Regina, punch it in, make a donation. We get to plant trees with that and reduce the greenhouse effect."
Anderson is hoping donations from residents, tourists and governments will add up to an annual spring planting regime to reforest areas of the river valley where conservation was not always a priority - for example, areas used as borrow pits for making roads.
"Some of those areas have been denuded of their natural tree cover and canopy. We would plant those areas with native trees and shrubs," he said.
Tom Hawboldt, the main race organizer for the North West Mountain Bike Club uses the trails in the river valley two to three times a week. He was pleased to hear efforts are underway to reclaim the area.
"The river valley is an undiscovered paradise almost. Undiscovered at times means almost neglected as well. It would be wonderful to have more trees," he said.
