David Attenborough's A Life On Our Planet

#233
This week I watched David Attenborough's excellent documentary film A Life On Our Planet on Netflix. David himself describes the film as his witness statement of the destruction of the bio-sphere that he has witnessed in his lifetime. It is harrowing viewing but ends in an optimistic call to action about what needs to be done to stop ourselves from destroying the planet. It is mandatory viewing for everyone, especially for those with children or in positions of power or influence.

Bill Gates On Vehicles

#226
Bill Gates published a blog post about his thoughts on the future of transport, in particularly vehicle transport. Electric vehicles are great for short haul, provided the efficiency of battery weight to range is improved. He sees the future of long-haul transport in biofuels, that can take CO2 from the atmosphere and combine with water to create hydrogen without any waste. These biofuels power vehicles and extract CO2 from the air, a win win!

Rock Dust CO2 Absorption

#220
A nation by nation assessment published in Nature shows that adding crushed rock (finely crushed basalt) to farmland could absorb up to two billion tonnes of carbon dioxide from the air per year. The technique is called enhanced rock weathering and by-products of iron and stell manufacturing, and construction, could be processed to produce the rock dust needed.  (H/T to Jenn for sharing this.)
