35.(6 points) Have you ever heard of the "green super rice" that "has no pesticides and is resistant to insects, eats less chemical fertilizers and grows strong, and lives only by rain"?

As a big country in rice production and consumption in the world, China is the country that uses the most pesticides and fertilizers in the world, and the water consumption for rice accounts for more than half of the total water consumption in China. Residual pesticides finally enter people's dining tables; Long-term use of chemical fertilizers makes the soil harden; The increasing water consumption has seriously damaged the farmland ecosystem.

Scientists in China started the "Global Rice Molecular Breeding Program" and established the largest rice gene database in the world. Scientists study the function of each gene and then cultivate "super rice" with high yield and disease resistance. In 2008, the water-saving and drought-resistant "green super rice" cultivated by Shanghai scientists has been popularized in some parts of the country.
