Well, even without industrial pollution, atmospheric carbon dioxide dissolved into clouds makes rainwater at least slightly acidic. Oh!
嗯，即使没有工业污染，大气中的二氧化碳被云层吸收后也会导致雨水呈弱酸性。噢!
But here in Indiana, a rain is almost ten times more acidic than natural rainwater.
但是，印第安纳州这里的雨水酸性比天然雨水高出几乎十倍!
Why? Well, a lot of power plants and other factories that burn coal to make energy.
为什么啊？是这样，这座中西部州有很多发电厂和其他工厂，它们都是靠燃煤来生产能源的。
Burning coal releases sulfur and nitrogen oxides into the atmosphere, which make rain more acidic.
煤燃烧后会将硫和氧化氮释放到大气中，导致雨水呈较强酸性。
That does sound good! What would happen if you drink our rainwater?
听起来很有道理！如果饮用这些酸性雨水会怎么样？
Nothing! The acid content isn't high enough to harm humans, and it doesn't affect the taste of the water, either.
无碍。雨水的酸含量不高，不会对人体造成伤害，也不会影响水的口感。
But acid rain can damage lakes, streams, and harm trees at high elevations.
但是，酸雨会破坏湖泊，溪流，以及高海拔地区的植被。
Also, acid rain accelerates the decay of buildings, statues, and sculptures.
而且，酸雨还会加快腐蚀建筑物，雕像，雕塑等。
