永续美国农业

和七十年前相比，美国拥有更为广袤的森林。事实上，美国每年种植超过十亿棵的树苗，相当于每天270万棵树。现代森林管理不仅仅确保树木要复种，而且每年在美国森林里成长的树木要多于被砍伐的树木。当减碳应对气候变化日益重要时，木材对环境的裨益不可否认。

• 木材是唯一可再生及消耗太阳能生成的主流建筑材料
  

• 与其它建筑材料相比，树木的砍伐及变成产品的过程需要较少的能源（指较少的碳排放）
  

• 木材可重复使用、可循环利用，能用作生物质燃料并且可以生物降解。

U.S. Agriculture is Sustainable

The United States has more trees today than 70 years ago. In fact, over 1 billion seedlings are planted in the United States every year – the equivalent of 2.7 million trees every single day of the year. Modern forest management ensures not only that trees are replaced, but that every year more wood is grown in U.S. forests than is harvested.  As carbon reduction becomes increasingly important in efforts to address climate change, the compelling environmental benefits of wood are undeniable. 

• It is the only mainstream construction material that is renewable and produced using solar energy.

• Trees require less energy (meaning less CO2 emissions) to harvest and convert into finished products than any other construction material.

• Wood is reusable, recyclable, can be used as biomass fuel and is biodegradable.
