Effects Of Pollution

The effects in living organisms may range from mild discomfort to serious diseases such as cancer to physical deformities; ex., extra or missing limbs in frogs.

Experts admit that pollution effects are quite often underestimated and that more research is needed to understand the connections between pollution and its effects on all life forms.


How Can Organisms Adapt?

Fish are known to exhibit biochemical responses to PCB concentrations in their tissues, but the ecological consequences of this contamination are unclear.

An example of a structural adaptation is the way some plants have adapted to life in the desert. Deserts are dry, hot places. Plants called succulents have adapted to thisclimate by storing water in their thick stems and leaves.
