大家一起来植树！我们的参与是改变未来的开始。
树非常重要，他们每天会为我们输送新鲜的氧气，帮助我们消除环境中的有害废气。世界地球日主委会的目标是在2020年之前，全人类可以为自己种下78亿棵树，这意味着每一个生存在这个地球上的人将拥有一颗属于自己的绿色。
我们要采取行动，积极参与到植树的活动中，保护现有的森林资源，守护山林、增加城市绿地。这样我们在未来会拥有一片更干净、更健康、更舒适的生存空间。
为地球种下一棵树，为子孙留下生命的希望！
Trees help combat climate change.
They absorb excess and harmful CO2 from our atmosphere. In fact, in a single year, an acre of mature trees absorbs the same amount of CO2 produced by driving the average car 26,000 miles.
Trees help us breathe clean air.
Trees absorb odors and pollutant gases (nitrogen oxides, ammonia, sulfur dioxide and ozone) and filter particulates out of the air by trapping them on their leaves and bark.
Trees help communities.
Trees help communities achieve long-term economic and environmental sustainability and provide food, energy and income.
