…-they can be replaced naturally and cannot be seriously depleted. This green energy also reduces the cost of operation. As a type of clean energy, they emit little or no harmful chemical pollutants into the air, so they have a minimal impact on the environment.

2. Use the ideas in the boxes to write an essay about the advantages and disadvantages of consuming organic food.
Nowadays, food safety issues are regarded as one of the most important problems people, especially those in developing countries, have to face. As a result, consumers tend to pay more and more attention to the organic food. Some think it should be widely promoted while others assume it has certain limitation when in use based on its advantages and disadvantages.
First of all, organic food is very clean and safe for people’s health because there are fewer chemicals or pesticide sprayed on it. Consequently, consumers will have more chances to use nutritional foods without any doubt. In addition, farmers use co-friendly methods to cultivate so they spend fewer expenses on farming and are able to make big profits from selling their products.
In contrast, organic food has its own limitations, particularly for people with certain financial and geographical conditions. Producing organic products takes a lot of time and efforts and depends on many farming conditions such as suitable lands, weather, and farming methods. Accordingly, the price of organic food is quite expensive and buyers have fewer choices in favorite foods.
