The environment is a whole, it is an eco system, made up of many individual parts. Each of those parts are dependent on the other for survival, for reproduction, for growth etc. The eco system as a whole has balances and checks.
If one part of the system is taken away then it may be very damaging for other parts of the system even within the same species or variety of species. So, for example, looking at pulp trees which are grown as a crop, versus a mixed natural woodland with a variety of trees of different ages. These pulp trees are grown as a cash crop. They are all planted in bare land, all at the same time, so they can be harvested at the same time. So pulp trees do not have the benefit of mature trees giving them aeorsol, beneficial root associates, acting as a wind break, acting as shade, storing water and releasing it as needed.
Pulp trees are over illuminated, so they have over exposure to sunlight, which results in open textured, inferior, soft timber. There is lots of new evidence about the beneficial effects of microrhiza ectomycellium and endomycellium in soils. We, mankind, are only just learning about these, this ignorance is the real danger with mankind messing about in natural eco systems. Parts are interdependent, if we eliminate one part through ignorance of it's existence the whole system can be put at risk.

Because everything in the environment depends on at least SOME other things in the environment. People depend on plants for food for example.
