With this baby, we can drive on sand, gravel, mud, and even snow.

Jae：有了这个孩子，我们可以在沙地、砾石、泥地甚至雪地上行驶。

Sand, gravel and rock crushed together are melted down to make the glass used in every window, computer screen and smart phone.

一起粉碎的沙子、砾石和岩石被熔化， 制成用于每扇窗户、电脑屏幕和智能手机的玻璃。

So I think less than three percent of  the sand, gravel and resources we need is being transported over long, longer  distances.

因此，我认为我们需要的沙子、砾石和资源中只有不到 3% 被长途运输。
