bird watching is another activity initiated by the green earth, as a means of understanding the relationships between humankind and nature. professor zhao xinru of the biology department of beijing normal university has, since 1997, at the invitation of the bird watching group, given lectures and instruction to the group on birds and bird identification. after a period of study, group members can now distinguish almost 100 species of birds, including the whooper swan, the lapwing, and the heron. they have also twice participated in the hong kong international bird watching contest and achieved impressive results. according to wang yongchen, founder of the green earth and journalist at the central people's broadcasting station, the organization is currently engaged in the work of bird identification, with the aim of helping volunteers to gain a deeper understanding of birds and the relationships between birds and human beings. through her knowledge obtained from bird watching, zhong jia, a volunteer with the green earth, has found that excessive land reclamation has caused the bird habitat in beidaihe to shrink dramatically, hence the steady dwindling of their number. zhong jia made an appeal based on her findings to the relevant department, to protect this world-famous bird watching site. her action concurs exactly with the green earth's guideline, i.e. providing a scientific basis for the department concerned to stipulate policies on managing bird resources and their habitat. in , the green earth participated in work at the beidaihe bird identification station, thus becoming the first bird identification group mainly made up of volunteers.
unlike other environmental protection organizations, the global village of beijing (gvb) is particularly concerned with human beings and their community, rather than certain species of animals, plants or water resources. gvb mainly engages in publicizing the 5r (reduce, reevaluate, reuse, recycle, and rescue) green life style. liao xiaoyi, founder of the gvb, says that their main thrust is to help people make the decision voluntarily to choose a nature-friendly way of life, exercise their rights, and stand by their obligation to protect the environment. since the day the gvb was founded, liao and her colleagues have made investigations into garbage sorting in different communities, and helped neighborhood committees in beijing's xicheng district to establish pilot garbage sorting stations. the gvb has also cooperated with the environmental protection department to establish china's first pilot green community in the jiangongnanli community of beijing's xuanwu district. liao xiaoyi's dream is to make green communities into the most beautiful landscape in china in the 21st century.
