Vital services including internet access, weather forecasts and navigation could be put at risk by increasing greenhouse gas emissions, as well as growing space debris, a report has found.

Australian aerospace experts warned the problem could hit households in rural and remote areas of the nation hardest, and called for worldwide regulations to prevent the cutbacks.
