Wednesday marks the 40th Earth Day. China celebrated the day with the theme of "Understanding the Earth, Sustainable Development".
People across China held various campaigns to raise awareness.
In Zhejiang Province in East China, volunteers promoted energy saving and an environmentally friendly lifestyle.
Children in Jingdezhen City, Jiangxi Province, took part in a painting contest.
To keep the blue part of the earth clean, the army organized a beach clean-up along the coast of Shandong Province.
Troops in the northeastern province of Jilin went to schools and led activities for pupils.
Further environmental education came from the Ministry of Land and Resources. Its report says China is rich in natural resources, but the country's per capita average of those resources is low. Fertile land is scarce, with limited land available for sustainable development.
