In 2006, a study in Yulin calculated people's ecological impact and the environment's ability to handle it. Results showed each person needed 1.272 hectares of land but the region could only support 1.716 hectares per person. This means there was a deficit of 0.444 hectares for each person. The study revealed that Yulin's use of natural resources is growing, surpassing what the environment can provide. This mismatch is putting pressure on the ecosystem and making sustainable development difficult. In essence, Yulin is using more resources than its environment can handle, risking its ecological well-being.
