A new way to restore Earth’s biodiversity—from the air

Every year, humans change 10 million hectares of land, and not for the better. Right now, there is 【小题1】 much damaged land around the world that we need to fix this fast. Fortunately, technology can help. Restoration is 【小题2】 enormous, complex challenge. It cannot be done by 【小题3】 ( simple ) planting trees. We need to bring native ecosystems back 【小题4】 life, which requires deep 【小题5】 ( ecology ) expertise. Until now, we have been limited to poor copies, like vast plantations of a single kind of tree.

But drones (无人机) change that by allowing us 【小题6】 ( gather ) data and plant the right mix of vegetation (植被) quickly. And the machine-learning 【小题7】 ( analyze ) enables us to monitor our restoration work. For example, in Australia, we’re using drone - based planting and ecology - trained AI to restore thousands of hectares of land mined for coal. Many native forests here in Australia 【小题8】 ( destroy ) by catastrophic bushfires over the last few years. This means reduced food sources and safe habitats for koalas. A new project will accelerate the restoration of thousands of hectares of koala forests.

With these technologies 【小题9】 ( combine ), we’re able to expand restoration from a small island to an entire continent. We can return forests to land 【小题10】 a mine used to be, or recreate ecosystems like the one we’re hoping to restore on Lord Howe Island.

This year, August 15th marked China’s first National Ecology Day, 【小题1】 aims were to raise awareness of environmental protection and address unlawful activities and safeguard the development of forestry and grassland resource by law.

The establishment of National Ecology Day will enhance ecological understanding among the public and help the nation 【小题2】(well) participate in global environment and climate governance.

The move 【小题3】(see) as part of China’s efforts to build an ecological civilization, a concept that glorifies balanced and sustainable development and harmonious coexistence between 【小题4】(human) and nature 【小题5】 promotes the building of a community with a shared future for mankind.

China’s laws and administrative regulations 【小题6】(involve) the environment and ecology, 【小题7】(base) on what environmental difficulties villagers are eager to solve and what ecological measures should be taken urgently from their opinions, have laid a solid legislative (立法的) foundation 【小题8】 the ecological civilization.

【小题9】 makes Aug. 15 special is that on that day in 2005, the concept of “lucid waters and lush mountains” was first put forward, being 【小题10】(value) assets.
