A lot of the food you buy is shipped halfway around the world, and yet transportation still only accounts for around 3% of the total emissions from the product. It’s less for items that doesn’t need cooling, so it is thoughtful, but not relevant to take into consideration.
My organization recently funded a project, that clearly showed that hemp was the most sustainable choice, based on both emissions, pesticide, energy and water use etc.
Going to Everest Base Camp in about a year and do a bit of winter stuff up here in Scotland. Grappling with choosing a sleeping bag that's comfortable to -13 or so. Seems that nothing synthetic matches down in terms of weight/warmth/pack size... although they do have the waterproofiness advantage.
Any one have any suggestions for something non-down? I might try to get a second-hand down one otherwise.
Edit: how ethical is ethical down? Am I better with natural/biodegradable down than synthetic stuff produced from oil? Apparently down has a lower carbon footprint? And so on... Just looking for random opinions basically.
