Ecologically sustainable development focuses on A

B
eliminating the national debt by maximizing the flow of matter and energy resources.

C
minimizing pollution costs.

D
controlling human population size and resource use in order to control carrying capacity.

What are the options?

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
