Without the right growing conditions, trees cannot get really big, and there is some evidence to suggest tree growth could slow in a warmer world, particularly in environments that are already warm.

没有合适的生长条件，树木就不能长得很高大。还有一些证据表明，在世界气候温暖的时候，尤其是在原本已经很温暖的环境里，树木的生长可能会放缓。

Without trees our entire world would be a much drier place.

没有了树木，我们整个世界都将会是一片非常干燥的大地。
