Food waste is one of the leading causes of climate change. Farmers in Kenya are wasting up to 50% of their harvest when their crops are rejected for cosmetic reasons or dumped because of last minute order cancellations. Millions of tons of food waste ends up in landfills and the decomposition creates methane. Food waste generates as much green house gases as road transport and four times the level of aviation. Activists say this should not be happening in a country where many still suffer from hunger.
