Vegetation is the basic instrument the creator uses to set all of nature in motion.
Approximately 80% of our air pollution stems from hydrocarbons released by vegetation, so let's not go overboard in setting and enforcing tough emission standards from man-made sources.
The only technology that can 'see' beneath the ground is radar imagery. But satellite imagery also allows scientists to map short- and long-term changes to the Earth's surface. Buried archaeological remains affect the overlying vegetation, soils and even water in different ways, depending on the landscapes you're examining.
One who neglects or disregards the existence of earth, air, fire, water and vegetation disregards his own existence which is entwined with them.
Wealth and vegetation go together, and that exacerbates environmental injustice. The poor bear the burden of degraded environments.
