I think the national forestry authorities should formulate a mechanism to mobilize the whole people to plant trees, set aside a certain number of shelter forest construction areas in Tianjin for the whole people to plant trees for adoption, arrange technicians to give on-site guidance in various planting areas all the year round, and encourage the residents of the whole city to carry out afforestation activities with various themes. For example, Tianjin Environmental Protection Bureau and Tianjin Greening Department can organize nationwide voluntary tree planting activities for couples' wedding anniversaries, children's birth anniversaries, children's birthday anniversaries, family members' death anniversaries and major legal holidays, so as to improve Tianjin's ecological environment, benefit the people and practice the concept of sustainable development. At present, individuals have the idea of investing in voluntary tree planting, but they can't know who can fulfill this wish from the media such as the Internet. I believe that everyone in Tianjin who loves his hometown has the same wish.

Desert sand control and vegetation restoration, water shortage and poor water retention capacity of desert soil make tree planting and sand control a big headache. Not long ago, when I was changing my son's diaper, I thought that we could add water-retaining substances in diapers to desert soil to improve the living environment of vegetation, promote its vigorous growth as soon as possible, and improve the ability of trees to resist drought and preserve moisture. It is hoped that the engineers and technicians of China Sand Control Station can test the theory and practice.
