Why doesn't Elon Musk invest more in improving Earth rather than attempting to establish a human civilization on Mars?

Elon Musk is one of the most innovative and forward-thinking entrepreneurs of our time. While he has been criticized for his focus on space exploration, he has repeatedly stated that his goal is to improve the long-term survival prospects of humanity.

One of the main reasons why Musk has turned his attention to Mars is that he believes that it is essential to establish a backup plan for humanity in case of catastrophic events on Earth. Musk has often talked about the possibility of a third world war, a super volcano eruption, or an asteroid impact, which could cause an extinction-level event. He believes that by establishing a self-sustaining human settlement on Mars, we can ensure the survival of our species in the event of such an event.

Musk has also talked about the need to reduce the cost of space exploration to make it more accessible to the general public. He believes that by developing reusable rockets and other technologies, we can significantly reduce the cost of space travel and make it more affordable for ordinary people. By making space travel more accessible, Musk hopes to inspire future generations to pursue space exploration and continue to improve our understanding of the universe.

Despite his focus on space exploration, Musk is also a strong advocate for improving life on Earth. He has invested heavily in renewable energy technologies such as solar power and electric vehicles. Musk believes that by transitioning to a sustainable energy system, we can reduce our dependence on fossil fuels and significantly reduce greenhouse gas emissions. He has also talked about the need to improve education and address income inequality, which he believes are essential for building a better future for everyone on Earth.
