The document discusses several environmental problems caused by human activity, including pollution, depletion of natural resources, and climate change. It notes how industrialization led to increased pollution from smokestacks and waste. A lack of attention to the impacts on the full ecosystem has led to issues like global warming, water contamination, soil erosion, and loss of biodiversity as rainforests disappear. The document warns that without respect for life and creation, there is no solution to the current ecological crisis affecting land, water, and other natural systems.

2. Environment Today

3. Environment Today
 19th century
 American immigrants sent a picture of their
new hometown which looks like this.

4. Environment Today
 These
smokestacks were a point of pride
because it implies that cities was
prospering economically.
“It was a small price to pay
for economic progress…..”

5. Environment Today
 20th century
 Industrialization spread
 Population increased
 Resources become scarce

6. Environment Today
 Because of INDUSTRIALIZATION

7. What is earth?
A single ecosystem, consisting of a
community of
animals, plants, microorganisms, and the
like.

8. Pope John Paul II
“We cannot interfere in one area of the
ecosystem without paying due attention
both to the consequences of such
interference in other areas and to the well-
being of future generations”
-The Ecological Crisis: A Common
Responsibility

9. Lack of attention….

10. Lack of attention…
 Leads to…..

11. Greenhouse effect
a process by which thermal radiation from
a planetary surface is absorbed by
atmospheric greenhouse gases, and is re-
radiated in all directions.
 Depletes the ozone layer leading to
GLOBAL WARMING

12. GLOBAL WARMING

13. Pope John Paul II says
 Ecological crisis is the result of profound
DISRESPECT FOR LIFE
 Withoutrespect for human dignity and for
God’s creation, there is no way out of this
crisis.

14. American bishops say
“A society that will easily dispose of
God’s good earth will also find
disposing of people easy as well.”

16. Ecological Crisis

17. LAND
 Used to grow food
 But now, subject to:

18. Waterlogging
 Saturation of soil with water

19. Salinization
a build up of salts in soil, eventually to
toxic levels for plants.

20. Soil Erosion
a natural process but soon becomes a
problem when human activity causes it to
occur much faster than under natural
conditions.

21. Status today:
 Farm land turned into desert, subdivisions

22. Use of rainforest
 Serve as home for plant and animal
species
 Medicines to be derived from tropical
species
 Helps in absorption and neutralization of
greenhouse gases
 Helps in the improvement of nutrients of
vegetation

23. With the loss of
rainforests, many will
suffer.
Lives of everyone would
be endangered.

24. WATER

25. Facts on water
consumption today
 Over 1 billion people lack access to
clean water in developing countries.
 Use of unsafe water lead to over 80%
diseases which kills more than 25,000
people everyday ( UN & WHO)

26. Contamination of water
 Industrialpollutants are major factor of
the contamination of world’s water supply
 Underground tanks’ leak and seep into
ground water
 Pesticides seep into ground, run off with
rain then contaminates groundwater and
nearby streams and rivers

27. Contamination of water
 Other sources of water pollution:
 Excess organic matter
 Thermal pollution
 Infectious organisms

28. Facts on water pollution:
 Oceans provide habitat for aquatic
creatures, food and drinkable water for
humans.
 But oceans are not immune from
pollution…..

29. Facts on water pollution
 10% of world’s coral reefs have been
completely destroyed; Philippines has only 5%
remaining coral reefs which are in good
condition.
 Cruise ships generates water pollution for
producing a big number of waste
 Every summer, nutrient pollution creates a
dead zone
 Every year, over 300,000
dolphins, porpoises, and whales die because
of entanglement in fishing nets

30. God created the
earth to nurture
not to destroy.
