2. Natural Disasters
Natural disasters are extreme, sudden events caused by environmental
factors that injure people and damage property. Earthquakes,
windstorms, floods, and disease all strike anywhere on earth, often
without warning. As examples, we've chosen disasters that have occurred
around the world throughout history.

7. Locust Pestilence in Israel
By Dave Copeland, Cameraman, NBC News
 Huge swarms of the newly hatched critters have
begun marching across the sand, devouring
everything in their path.
Israel’s Agriculture Ministry has deployed pickup
trucks, planes and helicopters to spray pesticides on
the locusts before they can inflict more damage.
Experts estimate that a swarm of 30 million locusts
will cause severe crop damage.

8. Locust Pestilence in Israel
Teams of exterminators are working from sunrise to
sunset, spraying the millions of young locusts as they
move across the ground.

10. Insect Infestation threatens coconut
Industry in Isabela City, Basilan
By Rene V. Carbayas
Tuesday 13th of August 2013
Scale insect (Aspidiotus Destructor Signoret), a soft-bodied
5mm long fluid-feeding insect is invading the coconut plants
and other palm and fruit with 15 barangays affected by the
pests.
Hardest hit was Barangay Lanote with 2,519 coconut trees
affected, followed by Maligue, Cabunbata, and Lumbang.

11. Insect Infestation threatens coconut
Industry in Isabela City, Basilan
there are many reasons why an outbreak of coconut scale
insect occurred, and one of them is bad agricultural practices
such as overuse or misuse of pesticides, particularly on the
vegetables and fruit trees planted under coconut plants.
“Pesticides also kill natural enemies and without them, insect
pests are free to multiply without control,” he said.

13. Examples of Pestilence

14. Pestilence in Bicol prompts P1 reward
for every dead rat's tail
January 24, 2009
Rat pestilence in the rice fields in Albay in the
Bicol Region has prompted local authorities to
offer reward of P1 for every tail that comes from a
dead rat
The project, launched by the town government, is
called "Bawat Buntot Piso Project" (A Peso for
Every Tail Projects).

15. Effects of Pestilence
Wandering
the innate survival instincts of
pests/ animals cause them to
wander into unnatural places in
search of food.
The outcome is, animals are
killed because of property
damage and human injury.

16. Effects of Pestilence
Damaged Ecosystems
animals can wreck the ecosystem and surrounding landscape.
The overpopulation of deer throughout areas of the United States is
destroying the forest and hindering the diversity of tree species

17. Effects of Pestilence
Lack of Food
Pestilence damages
crops and properties
farmers cannot produce
sufficient foods and other
resources

18. Effects of Pestilence
Disease Outbreak
Pests can be a vector of bacteria, fungi
and viruses that can cause diseases
Uncontrollable spread of disease can
cause the epidemics to humans
Bubonic Plague

19. Pestilence Control
provide a list of experts available for advice, including
regional experts
lists of insecticides and rodenticides that are readily available
in appropriate formulations
Using bait and fumigation
Community Extermination Projects

20. Conclusion
Pestilence is considered one of the natural disasters
which cannot be prevent. Examples are locust, bees,
dragonflies and other insects infestation; overpopulation of
wild animals and plague of rodents. This phenomenon
damages properties and crops which may cause lack of food
and resources. It can also bring epidemics in humans.
Pestilence control such as extermination projects, fumigation
and bait must be done once occurred to avoid further spread.
