This document contains an environmental science lesson that discusses sustainability and different types of resources. It defines sustainability as "meeting the needs of the present without compromising the ability of future generations to meet their own needs." The document categorizes resources as perpetual renewable resources, intermediate renewable resources, and non-renewable resources. It provides examples for each category such as solar, wind, and geothermal energy for perpetual renewable resources. The document also discusses how resources like fresh water, soil, crops and trees can be overused if regeneration rates are exceeded, making them intermediate renewable resources. Non-renewable resources like fossil fuels are finite and include oil, natural gas, coal, and nuclear energy.

13. Perpetual Renewable
Resources
From: EconomicPoint.com:Perpetual
resources are renewable resources that
cannot be exhausted, regardless of their
rate of use. Perpetual resources are natural
resources, because they are provided by
nature without human intervention.

15. Solar Energy
SOLAR ENERGY COMES FROM
THE SUN.
IT DOESN’T DECREASE WHEN
USED.
SOLAR ENERGY CAN BE
CONVERTED INTO ELECTRIC
POWER OR CAN BE USED AS
THERMAL ENERGY.
16. THERE ARE 2 WAYS OF
PRODUCING ELECTRICITY
FROM SOLAR POWER:
17. Solar thermal
electricity
A high temperature collector
concentrates sunlight (using
mirrors or lenses) onto a small
area. The heat generated is used
to drive a heat engine (like a
steam turbine) that generates.
19. Wind
The wind exists because the sun’s
energy heats different regions in
different ways. It doesn’t decrease
when used. With the use of wind
turbines, the wind can be used to
produce electricity.
20. Geothermal Energy
Geothermal energy is another form of
perpetual resource. It is derived from
the natural heat of the earth. In certain
spots, hot water or streams are near the
surface and can be piped for it’s direct
use (heat generation) or the steam can
be used to power turbines and
generate electricity.
21. Wave
Waves are generated mainly by
wind energy, which is in turn a
perpetual resource. Waves
contain mechanical energy that
can be used to produce
electrical energy.
22. Tidal Energy
Tides are the rise and fall of sea levels
caused by the gravitational attraction of the
moon and the sun on the ocean.
Tides are more predictable than wind, but
the high cost of investment and the limited
availability of site with high tidal ranges of
flow velocity, has limited the investment in
this source of perpetual resource.
23. Ocean Energy
There are other forms of perpetual resources that the ocean
could provide, for example marine currents, temperature
gradients and salinity gradients. The harnessing of this forms
of perpetual resources is still uneconomical and
under development.
25. Intermediate Renewable
Resources
If we didn’t use them, they would be perpetually renewable, but
because they require time (on human time-scales) to regenerate
or grow, we can overuse them until they are no longer available.
31. Non-renewable
resources
• Refers to a natural substance
that is not replenished with the
speed at which it is consumed.
• A finite resource.
• Nonrenewable resources are
extracted directly from the Earth.
34. Oil
Crude oil is a liquid fuel fossil fuel that
is used mostly to
produce gasoline and diesel fuel for
vehicles, and for the manufacturing of
plastics. It is found in rocks below
Earth’s surface and is pumped out
through wells.
36. Natural Gas
Natural gas is widely used for cooking and for heating homes. It
consists mostly of methane and is found near oil deposits below
Earth’s surface. Natural gas can be pumped out through the
same wells used for extracting crude oil.
38. Coal
Coal is a solid fossil fuel that is used for heating homes and
generating power plants. It is found in fossilized swamps that
have been buried beneath layers of sediment. Since coal is
solid, it cannot be extracted in the same manner as crude oil or
natural gas; it must be dug up from the ground.
39. Fossil fuel
Fossil fuels are made from
decomposing plants and
animals. These fuels are
found in Earth's crust and
contain carbon and
hydrogen, which can be
burned for energy.
40. Pressure and heat worked
together to transform the
plant and animal remains
into crude oil (also known
as petroleum), coal, and
natural gas.
Why? Because no matter how big you will do to spread awareness, to advocate for the environment, to create a community of eco warriors. The effort will only create a small and almost unnoticeable result. You said that through our small action, then collectively we can make change. But what you know what is the flaw in that statement? There can be small action but no collective effort. Humans won’t do things that is way beyond convenience. Only when it is absolutely necessary when we decide to fix the problem.
However, I make this statement today. Tomorrow is another mystery, the possibilities is endless. Yet, I do believe that all of this is our natural destiny and can quite be prophetical. Because, if we consult the bible, what is happening now! Is simply going according to the grand plan of the creator.
The reason why this resources can be perpetual because of their life cycle.
