同学你好~
“To strengthen the conservation of biodiversity and promote harmonious coexistence between human and nature have been an important content among international dialogue and communication.” 这句话存在语法错误，主语是不定式短语 “To strengthen...and promote...”，属于单数概念，谓语动词应该用 “has” 而不是 “have”，正确的表达是 “To strengthen the conservation of biodiversity and promote harmonious coexistence between human and nature has been an important content among international dialogue and communication.”
“fulfill the obligation to The International Biodiversity Convention” 中 “to” 的用法不太准确，此处表示 “…… 的义务”，常用搭配是 “fulfill the obligation of...”，所以这里改为 “fulfill the obligation of The International Biodiversity Convention” 会更合适。
“playing a greater role for...” 表述不太地道，常用搭配是 “play a greater role in...”，表示 “在…… 中发挥更大作用”，应将 “for” 改为 “in”。
希望对同学有帮助~
