盲目推进三北防护林工程导致地下水流失

树木生长需要大量的水,在本来干旱的地区盲目种树,而不是先改善植被,确实短见。

If the trees succeed in taking root, they could soak up large amounts of
groundwater, which would be extremely problematic for arid regions like
northern China.[9] For example, in Minqin, an area in north-western China,
studies showed that groundwater levels have dropped by 12–19 metres since
the advent of the project.

盲目种树还导致了生态多样性被破坏,本来宜居的动物被迫迁走,生态环境进一步恶化。

Furthermore, planting blocks of fast-growing trees reduces the biodiversity of forested areas, creating areas that are not suitable to plants and
animals normally found in forests. "China plants more trees than the rest of the world combined", says John McKinnon, the head of the EU-China
Biodiversity Programme. "But the trouble is they tend to be monoculture
plantations. They are not places where birds want to live."

中国已经开始在三北地区大量伐树,试图纠正错误

是在沙漠边缘或者外面,防沙尘,而不是在沙漠里面。

你有脑子的话麻烦用一下。要是那些地方原来就有树,还需要种树?

这是扯淡,中国的西北华北植被比以前好多了。
