Peak oil affects the lifestyle of organisms to a major extent. It is directly to the overproduction of higher levels of toxic compounds when ingested by organisms through air leads to problems like respiratory damage, cancer risk, liver damage, reproductive threat, etc.

Peak oil may be defined as the speculative point in time when the global production of oil acquires its maximum rate.

The steps that should be taken to avoid energy shortages in a post-peak -oil future are as follows:

Increase the dependency on solar energy.
Limit the use of non-renewable sources of energy.
Save major aspects of energy for the future.
Conserve and plant more trees.
Individuals need to make good habits of the utilization of energy-saving components and appliances that consume very less energy.
