The fact that organisms are adapted to survive in particular environments to explain why a. captive-breeding programs are often ineffective.
b. non-native plant species never flourish in new areas.
c. habitat destruction accounts for most extinctions
d. compromise is impossible on environmental issues.

The answer is C

Explanation:

Habitat destruction is the most cause of extinctions. As deforestation continues in tropical forests, it causes mass extinctions among organisms.

All species have specific food and habitat needs. The more specific these needs and the more localized the habitat, the greater the vulnerability of species to loss of habitat to agricultural land, livestock, roads and cities.  This is because the organisms are already adapted to the environment and any changes can prove disastrous for them.

In the future, the only species that survive are likely to be those whose habitats are highly protected, or whose habitat corresponds to the degraded state associated with human activity.
