Explanation:

The greenhouse effect traps heat in Earth's atmosphere. Without it, Earth's surface - average temperature would be much lower, around -18°C instead of the current 15°C. This would make it too cold to support our current ecosystem. While it would be inhospitable, it doesn't mean it would be completely barren of all life.

Answer:

A. too cold to support our current ecosystem
