It is beyond argument that organical food is beneficial to our health. However, our present food system is too chemical, but less organic! Here are some tips to make our food system more organic and less chemical.
First and foremost, our government shoud carry out some policies to support organic farming. For instance, farmers, who use organic farming, will be rewarded with certain money. Additionally, scientists should try their best to improve the strains of organic crops, which will help farmers improve the quantity and quality of organic crops. Meanwhile, farmers are required to be responsible for the food they grow. More importantly, we students should buy more organic food to encourage farmers to grow more.
Only when we manage to support organic farming can we lead a healthier life!
