Glossary: ET

The ET, or external tank, is the large orange tank mounted on the belly of the space shuttle's orbiter. It is filled with liquid hydrogen fuel and liquid oxygen oxidizer ahead of launch, and feeds both substances to the space shuttle's main engines during launch.

    The environment is a big thing here in where I live. I don't know about you but every liltte thing is a big difference. Oceans that make up deserts, deserts that make up woodlands, woodlands that make up the tropics, and so on. Imagine the animals or insects or even plants that live in one of these biomes.. One wrong move like cutting down trees can affect the ones living in the habitat. That is why I think I, nickyninja, is telling all reader to become eco-friendly. Everything living in habitats are just like us who live in towns, Africa, Brazil, Mexico. So, we should treat species the way us humans would want to be treated. Think about this, your favorite animal is a giraffe (wink,wink) and your best friend said their dad's friend's brother's mom's friend's husband kills giraffes. What would you say, how would you react? I know that's a liltte off topic, but I needed to prove a point some how. Think about being a friend to mother nature and we can make 2010 the best.
