Critical Thinking

Chapter 3:

Do you weigh things before taking action?
What are your contributions in maintaining a healthy and green environment?
How can a critical thinker like you help in sustaining a better world?

HOW DOES IT
HAPPEN?

Humans can live and survive on
Earth because of the heat that we
receive from the Sun. Some of the
radiation coming from the Sun
bounces back to space but a small
portion is trapped by gases that
make up our atmosphere.

CLIMATE
CHANGE

Climate change refers to a
long-term switch in
temperatures and weather.

Mankind has been the main
source of climate change,
primarily due to the
burning of fossil fuels,
which can produce heat-
trapping gases.

WHAT DOES
CLIMATE
CHANGE DO?

The effects of climate change can
range from drought, storms, heat
waves, rising sea levels, melting
glaciers and warming oceans to
direct harm to animals.

WEATHER VS
CLIMATE

Weather refers to
conditions
like rain, temperature and

Hydrofluorocarbon (HFCs) is an organic compound composed of three (3) elements: hydrogen, fluorine, and carbon. Used most commonly in refrigeration and air conditioning.

Carbon

A chemical element with the symbol C. This can be found in the Sun and other stars. The material is built up by a nuclear fusion in bigger star.

Nitrous

Is a chemical of which contains nitrogen.

Methane

(CH₄) is a type of gas that is colorless, odorless and flammable.

Greenhouse

Is a glass building in which plants are protected from cold weather. Works by converting light energy into heat energy. Light rays from the sun enter the greenhouse, where they are absorbed by plants and objects and converted to heat.

Energy

Energy is the ability or capability of being active.

Environment

VOLUNTEER

Take initiative by joining programs such as environmental clean ups.

EDUCATE

Be open minded when teaching other people about how to help save Mother Earth.

Andrew Mills from Reuters (October 28, 2020) Qatar is the world's largest producer of liquified natural gas and aims to expand LNG production to 127 million ton annually by 2027. It says its gas production helps combat climate change globally because it can help the world shift from high-polluting fuels like oil and coal to renewable energies.

ORGANIZATIONS INVOLVED:

Qatar Green
Building Council

The Qatar Green Building Council (QGBC) is a membership-driven non-profit organization that provides leadership and encourages collaboration in ecologically friendly green building design and development in Qatar. The Qatar Green Building Council also aspires to assist the overall health and sustainability of the environment, the people, and Qatar's economic security for future generations.

Friends of the Environment Centre

Friends of the Environment Centre (FEC) is an environmental organization with the goal of promoting environmental awareness and developing conservation initiatives

Ministry of Education and Higher Education

The eco-school program is the largest global sustainable schools program stipulated by the Foundation for Environmental Education (FEE). A two-year commitment program that inspires individuals to care for their surroundings by allowing them to actively protect it. It improves the environment for the better in which can result in cost savings for schools in terms of electricity expenses, water use, waste collection, and other areas. Reducing waste and collecting recyclable materials will have a significant influence on both the school and the environment.
