An Earthquake is a sudden tremor or movement of the earth's crust, which originates naturally at or below the surface. The word natural is important here, since it excludes shock waves caused by French nuclear tests, man made explosions and landslides caused by building work.
Vegans and people seeking milk alternatives have a number of options in addition to soy milk. Almond milk contains a significant amount of protein and flavor, or you can choose rice milk, oat milk or hazelnut milk. Coconut milk is another alternative, but this product has a richer, more intense flavor.
I love almond milk and have been gradually switching to the vegan lifestyle for just under a year now. I never liked drinking milk, so I use it primarily for cooking and baking, and the occasional bowl of granola. My husband is a big milk drinker though and he actually loves the taste of almond milk.
