Introduction
The role that the environment plays in supporting various
life forms cannot be overstated. The natural resources that are
provided by the environment have supported human and other
organisms in a number of ways. Forest for example are the acting
as air purifiers. They are sources of medicine, they create micro-
climate as they contribute to the atmospheric moisture recharge
also regulate infiltration rate. Water on the other hand is also
considered the second most important resource after oxygen. It
is known that all living organisms rely on it for their survival.
Therefore, any that disrupts its sully and distribution, tends
to disrupt the very survival of humanity and other organisms.
Environment that comprises various ecosystem play a very
important role in waste assimilation. Nevertheless, sustainable
management and utilization of the natural resources has not
been achieved [1]. Some of the factors that have this achievement
a nightmare is increased human population.
Results
The consequences of increase in human population on the
environment are diverse. Some of these consequences have
been associated with land fragmentation, soil degradation, air
pollution, pressure on water resources, and alteration of earth’s
climate among others. Harte (2007) recorded that environmental
degradation grows in proportion to population size, assuming
fixed per capita consumption and fixed modes of production, is
shown to be overly optimistic. It has been noted that increase
in human population impacts negatively on the environment.
Harte asserted that the impacts of human population increase
on the environment can be reached using the equation such as:
Environmental Impact = (Population size) X (per-capita
affluence level) X (Impact from the Technologies used to achieve
that level of per-capita affluence) This implies that apart from
impacts that result from direct human activities, the technology
adopted in achieving the per-capita affluence also impacts the
environment. For instance, the fishing methodology like use of
chemicals targeting fish impacts on other aquatic organisms. The
fish might also die indiscriminately as a result of the chemical
sprayed on water. Similarly, water quality is also degraded
by such technology. Human population continues to increase
annually and the challenges it poses on the environment will be

Abstract
Environmental management has been a global concern for various reasons. Environment has been perceived to provide support not only to
human but to other organisms as well. It forms habitat for various organisms and through support of vegetation growth ecological functions such
as recharge of atmospheric moisture is realized. The ecosystems such as forests, wetlands and water play a vital role in waste assimilation. Forests
act as carbon sinks and also contribute to air purification. They are also habitat for wild organisms like birds, snakes and other animals. On the
other hand, wetland ecosystem offer protection services for instance the buffer zone between open water and land that regulates and protects
the water from being contaminated hence pollution abatement. They also moderate climate as they contribute to the atmospheric moisture
recharge. Other services offered by the wetland ecosystems include storm water abatement, provides habitats and refugia for animal and plant
communities flood control, improve water quality, nutrient retention and /or recycling. Increased human population has greatly affected the
environment and especially these natural resources which support both human and other life forms. Rapid population growth especially in a
developing country like Kenya has put pressure on the available resources like water, forests and land in general. Increased population translates
to increased demand for food and space for settlement. As a result, people engage in intensive agriculture with application of inorganic fertilizers
that affect the environment negatively. They also encroach the protected areas like the Mau forest in Kenya that consequently lead to resource use
conflict between the communities and the government. Population growth also lead to over exploitation of resources like forests, fish, minerals
and even water. This study sought to review the impacts of population growth and the dilemma it causes on natural resources.
