text: "The planet (venus) has a surface of rocky sediment and includes familiar future". This is a intesting fact, my question to the auther would be , "Doesnt Mars have rocks and mountens? So, can mars be a sister planet to Earth as well or am I wrong?"I don't think community service is needed or required especial for school because that should be able to choose if you want to do that our not. It is help for to the world and if every one does it and can help earth but a lot of people don't have the time to do that some people have work or outside school activities and that can get in the way of doing community service. also the little free time that some people have they want to spend it on there self. Not on doing some thing that requires more work because than that person can get stressed out.
