As transportation grew more advance, we started moving efficiently yet more distant from earth. From land vehicles that put ease to our daily lives to aircrafts that send us high in the sky, we move one step every so often at the expense of our environment. Inventions improved our lives but it costs us greatly. We once walked the land with ease and we can still raise a foot to fight global warming. Walking improves our health and so as reduce our carbon footprint. As our planet needed us, we, as a planet of our own, should extend help to ourselves. We might only have our feet to walk with, but collectively, we can step up the cause.
