Environment Today
20th century
Industrialization spread
Population increased
Resources become scarce

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

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”

Responsibility

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

Pope John Paul II says
Ecological crisis is the result of profound
DISRESPECT FOR LIFE
Without respect for human dignity and for
God’s creation, there is no way out of this
crisis.

LAND
Used to grow food
But now, subject to:

Waterlogging
Saturation of soil with water
![Page 19: The scope of environmental problem](https://reader034.fdocuments.us/reader034/viewer/2022042701/55a07cbf1a28abed578b466c/html5/thumbnails/19.jpg)
Salinization
a build up of salts in soil, eventually to
toxic levels for plants.
![Page 20: The scope of environmental problem](https://reader034.fdocuments.us/reader034/viewer/2022042701/55a07cbf1a28abed578b466c/html5/thumbnails/20.jpg)
Soil Erosion
a natural process but soon becomes a
problem when human activity causes it to
occur much faster than under natural
conditions.

Status today:
Farm land turned into desert, subdivisions
![Page 22: The scope of environmental problem](https://reader034.fdocuments.us/reader034/viewer/2022042701/55a07cbf1a28abed578b466c/html5/thumbnails/22.jpg)
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
![Page 23: The scope of environmental problem](https://reader034.fdocuments.us/reader034/viewer/2022042701/55a07cbf1a28abed578b466c/html5/thumbnails/23.jpg)
With the loss of
rainforests, many will
suffer.
Lives of everyone would
be endangered.

WATER
![Page 25: The scope of environmental problem](https://reader034.fdocuments.us/reader034/viewer/2022042701/55a07cbf1a28abed578b466c/html5/thumbnails/25.jpg)
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)
![Page 26: The scope of environmental problem](https://reader034.fdocuments.us/reader034/viewer/2022042701/55a07cbf1a28abed578b466c/html5/thumbnails/26.jpg)
Contamination of water
Industrial pollutants 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
![Page 27: The scope of environmental problem](https://reader034.fdocuments.us/reader034/viewer/2022042701/55a07cbf1a28abed578b466c/html5/thumbnails/27.jpg)
Contamination of water
Other sources of water pollution:
Excess organic matter
Thermal pollution
Infectious organisms

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

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
![Page 30: The scope of environmental problem](https://reader034.fdocuments.us/reader034/viewer/2022042701/55a07cbf1a28abed578b466c/html5/thumbnails/30.jpg)
God created the
