<p>In order for humanity to progress and thrive, we must appreciate Earth as the spaceship it is. Our atmosphere, and the diverse ecosystems it sustains, are our vital life support system against an otherwise inhospitable space. Equipped with an astronaut mindset, we treat our natural resources as precious and human kindness as essential.</p>
<p>Arbor is developing a scalable and low-cost approach to reverse humanity&rsquo;s climate footprint, leveraging advanced rocket engine technology and Earth&rsquo;s own natural rhythms. We are designing, manufacturing, and operating systems that will restore balance to the planet and set the foundation for a global circular economy. Our technology converts waste into clean energy and fresh water, while permanently removing CO2 from the atmosphere. We're using the same technology developed to get humans off the Earth to now help us save it.</p>
