Step Ⅲ 迁移创新
活动五：想象与创造
Ask students to search for information about Ant Forest and discuss it.
Related information:
Alibaba’s Alipay announced that 100 million trees had been planted in the country’s deserts as the number of its Ant Forest users reached 500 million.
The nearly 1.4 million mu (about 93, 300 hectares) of forests had been planted as part of a non-profit project to combat desertification and promote a low-carbon lifestyle started by Ant Financial，See Foundation and China Green Foundation in August 2016.
Alipay users who engage in low-carbon acts like renting a bike，taking the bus，or simply walking are rewarded with “green energy” that is used to “water” virtual trees in their mobile phones. And when a virtual tree grows up, a real tree will be planted by Ant Forest. This function is embedded in the Alipay app.
This way of planting trees was recognized on October 23, 2018 by the National Afforestation Committee as a means for citizens to fulfill their obligations of planting trees.
In February 2019, Hema Fresh, Alibaba’s new retail-based supermarket chain, also joined in the Ant Forest scheme, allowing its customers to gain “green energy” if they choose not to use plastic bags while shopping.
The Chinese government attaches great importance to the protection and restoration of ecosystems and afforestation projects have been implemented for decades. China aims to increase the forest cover to 23 percent by 2020, and to 26 percent by 2035.
A new study using data from NASA satellites shows that the Earth becomes greener as a result of ambitious tree-planting programmes in China and India.
【设计意图】通过谈论日常生活中每天都能接触的“蚂蚁森林”，反思个人与环境的关系，谈论个人在环境保护中起的作用，从而鼓励学生加入环境保护中来。
