Ocean exploration VS. exploration Exploring new areas is always important.Space provides both medicinal and technological advancements, yet the ocean not only brings those about, but also has more benefits including jobs.For those who dream of exploring outer space, the development of high-tech spacecraft is essential.Fish is an important source of protein for poor people on Earth, but NASA will not feed the world with whatever it finds or plans to grow on Mars, Jupiter, or any other place.The ocean covers more than 70% of the Earth, yet we've explored only around 5% of it. This means there is so much more to explore in the ocean.On the other hand, Space has also provided many new human experiences, such as zero gravity training.This training has showed various effects on the human body, helping scientist to better analyze the human body.But just one spaceship costs billions of dollars.
