  • Buildings are being destroyed,

  • animals are dying,

  • and trees are not able to grow.

  • All because of rain?

  • Wait, I thought we needed this stuff?

  • Well, it's not just any kind of rain.

  • This is acid rain.

  • If a superacid like carborane,

  • that can disintegrate things instantly,

  • came raining down from the sky,

  • it would destroy everything in its path:

  • entire buildings,

  • cars and,

  • even you.

  • But luckily we won't be dealing with that.

  • Instead, we'll have something known as

  • acid rain falling from the sky.

  • Although its effects won't work like carborane,

  • the end result of acid rain will be much,

  • much worse for everything it touches.

  • Unlike normal rain, that is slightly acidic,

  • acid rain contains high levels of nitric and sulfuric acids.

  • This makes its acidity level a pH of around four,

  • which is similar to tomato juice.

  • Acid rain doesn't occur naturally.

  • It comes from humans polluting.

  • Chemicals and pollutants that are caused from

  • buring fossil fuels enter our atmosphere.

  • There, they mix with water and oxygen

  • to become acidic rain.

  • Luckily, a little bit of acid rain doesn't cause much damage.

  • We've already had instances like this before.

  • But what would happen if rain was always too acidic?

  • Although this situation isn't ideal,

  • you can at least be happy with the fact that

  • acid rain won't affect you directly.

  • Meaning, if acid rain touches your skin, it won't burn you.

  • But there are still many ways you can be

  • indirectly affected by the rain.

  • The main thing that will suffer is the environment.

  • Acid rain can severely weaken and eventually kill trees.

  • It penetrates the ground, draining valuable nutrients from the soil.

  • Some trees will have the waxy coating on their leaves stripped away,

  • leaving the tree unable to create energy through photosynthesis.

  • What else will be hurt besides the environment?

  • Buildings, roads and

  • other materials will slowly degrade due to the rain.

  • With acid rain, these things will erode much faster than they do now.

  • Entire cities will crumble over time due to the acid rain.

  • After acid rain hits the ground,

  • it will eventually end up in our lakes, rivers, and oceans.

  • All this acidity in the water will gravely harm the fish that live in it.

  • Some fish will be able to survive better than others,

  • but some, such as shrimp and mussels,

  • won't last long.

  • And if any fish are born when the water is too acidic,

  • they'll have a good chance of being born with deformities.

  • And if just one species of fish dies,

  • it can destroy an entire ecosystem,

  • due to that fish missing from the food chain.

  • Over time, all fish will die

  • due to their environment completely changing.

  • They won't be able to adapt quickly enough.

  • Water sources all around the world

  • will become completely devoid of life.

  • Now, I don't need to tell you that

  • this will seriously affect our food supply.

  • Fish are a major part of over one billion people's diets.

  • You'll have to say goodbye to sushi,

  • and fish & chips.

  • And how will acid rain affect you?

  • Did you seriously think that

  • you were going to get out of a WHAT IF scenario

  • completely unscathed?

  • All the increased sulfur dioxide that will be in the air

  • will cause you some severe lung problems,

  • like asthma and bronchitis.

  • With our trees slowly withering away,

  • our infrastructure being destroyed,

  • and huge parts of our food supply disappearing,

  • the Earth will become uninhabitable.

  • One way we could stop this would be to geo-engineer the weather

  • to act the way we'd like it to.

  • Or y'know,

  • maybe we could just stop polluting,

  • and the issue would resolve itself.

  • That's how we got into this situation in the first place.

  • Maybe, we could charge companies to pollute.

  • But we'll leave that story, for another WHAT IF.

Buildings are being destroyed,
