I have wrote about exploring space but our planet has also not been fully explored. Some historical sites are not allowed to be excavated due to current governments but with a world government, we can fully learn about our past that may help us in the present. We can study the arctic more and the earth all around the planet. We need to develop better technology to explore the ocean. Many medicinal ingredients come from plants and animals. Finding out all the flora and fauna around the earth would be very beneficial to humanity.
