A

Organic food is very popular. It is also expensive. Some organic food costs twice as much as non­organic food. Some parents and pet owners pay up to 200 percent more for organic food while some people think organic food is a waste of money.

There is one main difference between organic and non­organic food. Organic farms do not use agricultural chemicals, such as pesticides (杀虫剂). This guarantees that the products are natural.

Some people think “organic” means “locally grown”. Originally this was true. Over time organic farming became more difficult. The demand for organic food grew larger than the supply. Small companies had to sell out to large companies. There weren't enough organic materials. This made it difficult for many organic companies to stay in business. Today, many large companies have an organic line of products.

Is organic food more nutritious (有营养的)? This is part of the debate. Many farmers and consumers (消费者) believe it is. They think agricultural chemicals cause health problems, such as cancer. Many health professionals disagree. Few studies prove that organic food prevents health problems. Health specialists worry more about bacteria. These can come into contact with organic and non­organic food. Doctors recommend washing produce very carefully.

Most people agree that naturally­grown food tastes better. Is tastier food worth the extra money? This is a matter of opinion. Whether it is healthier or not may require more research. However, organic consumers argue it is better to be safe than sorry.
