How does over population affects the ecosystem?
Study and analyze the over population situation of the picture below.
Main message of the picture above : Our population is fast growing, but our natural resources
in our ecosystems such as forests and seas do not expand. This shows the bigger the population,
the greater is the demand for consumption that put our ecosystems and natural resources in great
danger.
Why do you think this is happening in this area?
What do you think will happen to the total environment or ecosystems of the community if this
situation occurs?
Can you describe the relationship between the activities in the upland that also affect the
lowland and coastal areas?
What do you think are the effects or linkage of family planning in our natural resources or
environment?
Benefits provided by ecosystems to people are recognized as multifarious : they include
provisioning (food, water, fiber, genetic resources, fuel), regulating (climate, air quality, soil and
water control, disease), cultural formation (spiritual enrichment, aesthetic experience, recreation,
cognitive development or education) and supportive services (primary production, generation of
oxygen, soil formation). People have food to eat, water to drink, medicine to treat illness, oil to
have light or run machines. Having any of these defines roles and status in society – as trader,
buyer, leader, specialist, experts – sustained by cultural formation. We have clean air and good
harvest with good vegetative cover, nutrient cycles, irrigation, and soil control.
Biologically, the Philippines is considered a megadiversity country with impressive assemblages of
marine and terrestrial species in a broad range of ecosystems. Yet the archipelago’s unique flora
and fauna are threatened by increasing environmental degradation from habitat fragmentation,
pollution and over-harvesting of native species. These human-induced threats are compounded by
the increasing population growth which is expected to double in 2030 (to about 130 million, from
the current population of 85 million) using a population growth rate index of 2.36 percent. This
significant growth rate continues to increase the demand on natural resources for domestic,
agricultural and industrial consumption, thereby putting more intense pressure on the environment
or ecosystem.
The last 400 years have seen the transformation of the country from an expanse of lush and
contiguous rainforests to a patchwork of fragmented habitats. Today, only about 18 percent of the
natural forests remain, with only around three to six percent of primary forests or 800,000 hectares
intact (ESSC 1999). Populations of endemic and threatened species of flora and fauna are
declining, and many now face extinction as a result of habitat loss. Deforestation has been
attributed to commercial logging, fuel wood collection, slash-and-burn cultivation, human
settlement and pasture farming, among other things.
