Problem 1
Why is it useful to know about the species of plants and animals that live in some defined area, such as a park, county, or province? Is it useful to know about the ecological communities? How does this kind of information assist in planning for conservation and sustainable development?
Problem 2
Ecologists usually consider native species to have greater "value" than non- native ones. Why do they think this way? Is the rationalization only scientific, or does it include an element of non-objectivity?
