So what can China learn from other countries? The Finnish capital, Helsinki launched an organic food eating campaign last September, raising public awareness that eating organic food is not only good for health, but also the environment.
Just a few blocks from Helsinki city center, clusters of green vegetables.
These vegetables have been planted in large plastic bags filled with organic fertilizer.
This government project shows residents how to grow organic vegetables.
The city’s government also transformed a discarded slaughterhouse into an organic food center, which hosts food exhibitions and a restaurant.
All the dishes are made with organic vegetables, and the cooking procedures are simple.
"It’s more pure, it’s more natural product. And also it’s a better option for the environment. Because we know that our food choices also affect the environment. Organic is one of the best options," Helsinki Food Expert Ville Relander said.
According to some European food research organizations, although many countries have increased the yield and appearance of farm produce, fruit and vegetables have fewer vitamins and minerals.
Harmful substances like pesticides in food are one of the causes of diseases such as cancer and diabetes.
Consumers who care about their health, are willing to pay more for organic food.
Now, more and more organic food stores are opening in Helsinki, normally selling vegetables from small farms.
"Buying more organic food and to that we hope that it will slowly affect the way the farming is happening in Finland and also the pricing of organic food. Because so far the quantities have been quite small and the prices have been relatively high in Finland. But by the strategy, we hope we will affect the way the farmers are farming their food," Helsinki Food Expert Ville Relander said.
With customers’ support of organic food and government’s advocacy of organic agriculture and livestock, more and more farmers have turned to producing organic vegetables and food.
The Finnish government says in the next seven years, it will work to increase the country’s organic farmland acreage from the current 9 percent to 20 percent.
