Shaped by natural processes and the increasing influence of human activities, biodiversity forms the web of life of which we fully depend upon for thousands of years. On October 11-15 this year, the UN Biodiversity Conference (COP15) is held in Kunming, China to convene governments from the world to agree on a new set of goals for nature over the next decade.

21 targets are proposed in the Post-2020 Global Biodiversity Framework, among which sustainable management of agriculture and forestry serves as the main measure. Agriculture might be generally neglected as a great constituent to maintain biodiversity. But as technology arises in rural areas, there have been more applications of tackling biodiversity loss in agriculture, from less use of chemicals to land restoration.

From fields to pastures, crossing rivers and forests, drones and robots are now the integral part of maintaining the balance of nature. They are acting as the new type of "painkiller" in natural habitat under potential threats to lift the pain of environment.
