How Did Yuan Longping Revolutionize China’s Rice Production?

①Yuan Longping was born in 1930 in Hubei. As a child, he was very interested in plants and other living things. He grew up to be a curious and hard-working plant scientist. Yuan wanted to solve the problem of food shortages, so he began conducting experiments to improve rice yields per hectare (10,000 m²).

②Plants come in many different varieties; for example, some types of rice have long grains, while others have short grains. For centuries, people have been crossing different plant varieties to create hybrids. Such plants proved to have desirable qualities from both parents. Yuan believed that it was possible to do the same with rice. He tried different ways of creating rice hybrids, only to discover that his attempts were unsuccessful.

③Even though it often seemed too difficult to complete this task, Yuan didn’t give up. After many years of hard work, his experiments finally bore fruit. This was a major discovery since no one had previously been able to cross two different kinds of rice. It had a huge impact: the first hybrid rice variety increased China’s rice production by 100 million tonnes in little over a decade.

④Yuan didn’t stop there — instead, he continued experimenting and created super hybrid rice with yields over 15 tonnes of rice per hectare. Thanks to Yuan’s work, China became self-sufficient in rice. Our country continued to increase its rice yields to become one of the biggest food donors in the world. In 2019, he received the Medal of the Republic for his outstanding contributions. At the age of 90, Yuan Longping still hasn’t retired. With a growing global population, the world needs to produce enough food to feed everyone, and Yuan is working to make this happen.

3 . The Last Straw?

Every second, the world uses 160,000 plastic bags — that is a total of over five trillion per year. Up to 99 percent of these plastic bags hang around for at least 1,000 years and pollute Earth. And yet, plastic bags are hardly a necessity in our lives. Of all the changes we could make to create a more sustainable lifestyle, a total ban on plastic bags should be simple.

At the beginning of 2021, Shanghai put in effect a ban on all plastic bags in shopping malls and supermarkets, as well as a ban on non-degradable plastics in many other areas. Over the years, individuals and companies have worked to replace plastic items, such as cups and straws, with paper ones.     1    .

Customers complain that paper straws often become soft and break before they can finish their hot drinks. Experts, however, have repeatedly stressed plastic substitutes (替代品) are not the ultimate solution, and that our consumption habits need a bigger change.

In college, one of my environmental science professors promoted a type of waste-free living. She carried around a small glass jar with her, and in it was all her trash she collected for the entire year. She was able to do this by bringing her own cup to Starbucks, her own bags to the shops, and never buying anything that came wrapped in plastic. Her food waste also became compost.     2    .

Plastic bags are incredibly easy to forget about when they become increasingly common.     3    . Once they are in the trash, we take it for granted that they are someone else’s problem. The sad fact is that plastic bags break down into microplastics which then get mixed into the air, soil and water, and eventually end up in plants, animals, and our very own human bodies. So what are you going to do about them?
