How Many Humans Can The Solar System Support?

The solar system can potentially support 80 million-trillion humans if we build a Dyson sphere around the sun. A Dyson sphere is a spherical (and possibly habitable) structure built around a star to capture its energy. Were we to build a Dyson sphere — using the whole of Jupiter for materials — with a radius as large as the distance between the surface of the sun and the earth, we would be able to provide energy for the habitats of these 80 million-trillion people.

The Yorkshire man’s brain’s proteins were bunched up together, much like how dementia causes brain proteins to bunch up into plaques. This bunching up, or aggregation, could continue even after death, turning regions of the brain into hard masses. Read full article here

Some of these include using more energy-efficient equipment, reducing waste and water consumption, and developing more sustainable products. While these actions do help, they’re using them to hit corporate social responsibility goals, not genuinely in the interest of mitigating climate change on a larger scale. Read full article here
