To avoid catastrophic global warming, people need to cut way down on their meat and dairy consumption, a new report on climate change says. Four modest servings of meat and about a quart of milk a week are all we should be consuming, the Guardian reports. And the report urges government programs to limit emissions, because consumers won’t make these changes voluntarily.
Food production is responsible for almost one-fifth of carbon emissions in Britain, the report by UK-based Food Climate Research Network found, with meat and dairy accounting for half of that. But meat and dairy aren't the only guilty foods
—we should also downgrade our consumption of unnecessary treats like chocolate and beer.
