Vulnerability of food chains
Other Names: Fragile food webs
Vulnerability of food supply
Nature: Food chains are the networks of feeding relationships which interlink different species within a biological community. Particular links in such networks may be threatened or eliminated by the action of man-made products (such as pollutants), thus placing all the members of the biological community in danger, even though the others may not be directly affected.
Claim: Destruction of the ozone layer has potentially disastrous effects on single-cell organisms like plankton, at the base of the food chain.
