We should be grateful because we have home and place to live till now.

                   Earth is the only one that planet that contain air, water, and gravity that can make us 

                             survive.For instance,Earth is the third planet from the sun and the fifth

                   largest in the solar system.We as human should protect our earth,so that it can be used 

                             for a long term.Its for our future next generation and its important for us 

                   to care our earth.Nowadays,many pollution that can effects our earth like air pollution,

                            sound pollution,thermal pollution and water pollution.Its not good for

                   earth and you can see its effect in long term time.Dont you think that our earth  now is

                            get heated and its because of us.I suggest that we plant more tree,so that

                    we can keep our earth balance.
