Local and Global Environmental
Issues and Problems
A. Deforestation
EXTINCTION
is the displacement of the upper layer of
soil, it is one form of soil degradation.
This natural process is caused by the
dynamic activity of erosive agents, that
is, water, ice, snow, air, plants, animals,
and humans.
B. WILDLIFE DEPLETION
Extinct animals in the Philippines
Endangered animals in the Philippines
C. Water Pollution

D. Air Pollution
E. Destruction of Coastal Resources
F. Acid Precipitation
Activity
1. Is the contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and
groundwater).
2. A group of living organism of the same species living in a certain place.
3. A group of organism that have certain characteristics in common and are able to
interbreed.
4. Occurs when the last member of the species dies.
5. Variety of life in an area.
6. It is the displacement of the upper layer of soil, it is one form of soil degradation.
7. Removing or clearing of a forest that includes cutting of all trees.
8. Tiny particles of soot, dust and smoke.
9. Occurs when the population has become so low that it is possible of becoming
extinct.
10.Anything that limits the size of a population like certain environmental conditions
are called
1-6. Enumerate the different
Environmental Issues and
Problems
7-9. Causes of Deforestation
10-11. Example of Extinct Animals
12-15. Example of Endangered
Animals
1. Suppose 125 ants live in a 8 sq.m plot
of grass. What would be the population
density of the ants?
2. If 65 carabaos live in a 2.5 sq.m
area, what is their population
density?
