C. requires the restoration of ecosystems better designed to serve the needs of humans

Explanation:

For a very long time, the survival of plants and animals has been dependent on each other. The plant depended on animals for oxygen and the animals depended on plants for carbon dị oxide.

In recent times, this balance has been altered as humans (higher animals) have started engaging in activities that hurt the ecosystem such as Bush burning, deforestation and other agricultural practices.

In view of this, there is an urgent need for the restoration of ecosystems that suit human needs. This can be done by planting of more trees, reduction in industrial activities that involves emission of harmful gases and wastes into the air, land and water.
