This document discusses fundamental concepts of the environment from a lecture given by Wan Zuhairi Wan Yaacob at the National University of Malaysia. It covers four key topics: 1) population growth and its environmental impacts; 2) the concept of sustainability and balancing needs of current and future generations; 3) limitations of resources and debates around finite vs. renewable nature; and 4) hazardous earth processes and how to reduce risks from floods, earthquakes, volcanoes and other events. The document provides definitions, examples, and conclusions on each of these fundamental environmental issues.
Seas and oceans are very huge bodies of saline waters. Their distribution and dynamics are very influential in several ways. Understanding the properties of seawater is inevitable in oceanographic studies. Seawater is one of the most fascinating and plentiful substances on the planet. The basic properties of seawater and their distribution, the interchange of properties between sea and atmosphere or land, the transmission of energy within the sea, and the geochemical laws which are governing the composition of seawater and marine sediments, are the fundamental aspects studied in the subject oceanography.

Education is a process of development which includes the three major
activities, teaching, training and instruction. Teaching is social as well as
a professional activity. It is science as well as art. Modern education is not
in a sphere but it has a long and large area of study. Now a days most part
of the world population is facing different problems related with the nature
and they are studying the solutions to save the nature and global problems,
but on the second hand we even today do not try to understand our local
problems related to the nature. So for the awareness of the problems of
nature and pollution the higher education commission has suggested to
add the Environmental Science in the course of different levels.
Environmental Science is also well known as Environmental Studies in
the Indian Colleges and Universities. Before that it was the part of the
science but now a days it is a very common subject and higher education
commission has suggested including it as a general paper in all the courses.
The lithosphere is the solid shell of the planet Earth. That means the crust, plus the part of the upper mantle that behaves elastically on long timescales.
Environment literally means surrounding and everything that affect an organism during its lifetime is collectively known as its environment. In another words “Environment is sum total of water, air and land interrelationships among themselves and also with the human being, other living organisms and property”. It includes all the physical and biological surrounding and their interactions.
Environmental studies provide an approach towards understanding the environment of our planet and the impact of human life upon the environment.
Thus environment is actually global in nature, it is a multidisciplinary subject including physics, geology, geography, history, economics, physiology, biotechnology, remote sensing, geophysics, soil science and hydrology etc. Scope of Environmental Science Environmental science is a multidisciplinary science whose basic aspects have a direct relevance to every section of the society.
Its main aspects are:
• Conservation of nature and natural resources.
• Conservation of biological diversity.
• Control of environmental pollution.
• Stabilization of human population and environment.
• Social issues in relation to development and environment.
• Development of non-polluting renewable energy system and providing new dimension to nation’s security. Importance of Environmental Science Environment belongs to all the living beings and thus is, important for all.
Each and every body of whatever occupation he or she may have, is affected by environmental issues like global warming, depletion of ozone layer, dwindling forest, energy resources, loss of global biodiversity etc.
Environment study deals with the analysis of the processes in water, air, land, soil and organisms which leads to pollute or degrade environment. It helps us for establishing standard,Environment and Ecology for safe, clean and healthy natural ecosystem.
It also deals with important issues like safe and clean drinking water, hygienic living conditions and clean and fresh air, fertility of land, healthy food and development. Sustainable environmental law, business administration, environmental protection, management and environmental engineering are immerging as new career opportunities for environment protection and managements.
Need for Public Awareness With the ever increasing development by modern man, large scale degradation of natural resources have been occurred, the public has to be educated about the fact that if we are degrading our environment we are actually harming ourselves.
To encourage meaningful public participation and environment, it is necessary to create awareness about environment pollution and related adverse effects.

Until two decades ago the world looked at economic status alone as a measure of human development.
Thus countries that were economically well developed and where people were relatively richer were called advanced nations while the rest where poverty was widespread and was economically backwards were called developing countries.
Most countries of North America and Europe which had become industrialized at an earlier stage have become economically more advanced.
They not only exploited their own natural resources rapidly but also used the natural resources of developing countries to grow even larger economies.
Thus the way development progressed, the rich countries got richer while the poor nations got poorer.
poorer.
However, even the developed world has begun to realize that their lives were being seriously affected by the environmental consequences of development based on economic growth alone.
This form of development did not add to the quality of life as the environmental conditions had begun to deteriorate.
By the 1970s most development specialists began to appreciate the fact that economic growth alone could not bring about a better way of life for people unless environmental conditions were improved.
Development strategies in which only economic considerations were used, had begun to suffer from serious environmental problems due to air and water pollution, waste management, deforestation and a variety of other ill effects that seriously affected peoples’ well being and health.

Role of Academic Eco Clubs to Execution of National Policies on Environmental...Malhari Survase
The environmental awareness is the initial step ultimately leading to the ability to carry on responsible citizenship behavior. In view of this, the main aim is to assess the role of academic eco clubs to execution of national policies on environmental awareness among the college students. The required data and information is collected through various sources such as published books, journals, unpublished research thesis and online articles with the observations. The national policies and role of academic eco clubs in awareness and preservation of environment are objectively elaborated. With the consideration of the severity of the environment related problems the author tried to suggest the suitable remedies for the environmental awareness and sustainable development.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

• Garrett Hardin :
Total environmental impact of population = product of impact per person
x the population
• Population increases; impact
increases; more resources are
needed.
• Problems:• Pollution of ground and surface
waters;
• hazardous waste;
• exposure of people and human
structures to natural hazards.

• The present population is already over the
comfortable carrying capacity for the planet.
• The role of education is paramount; greatest hope for
population control.
• Pessimistic scientists:• Population growth will take care of itself thru disease and catastrophes
(famine lack of food) ; WAR
• Optimistic scientists:
• Hope we will find better ways to control the population of the
world within the limits of our available resources, space and other
environmental needs.

• The World Commission on Environment and Development defined
sustainable development in 1987:
“Sustainable Development is a form of
progress that ensures human development
and that ‘meets the needs of the present
without compromising the ability of future
generations to meet their own needs”

National University of
Malaysia
• Example 1
The office will provide employment and
so help in economic and social
sustainability. Building the offices will
use up natural resources but it does
contain recycled materials, have good
insulation and use solar power

• Example 2:
Organic farming does not use pesticides or chemical fertilizers.
Some people say that food produced organically tastes better
and is good for the environment. She produces less and so sells
her vegetable at a higher price compared to ones grown by
intensive farming. Not everyone can afford them. This could
affect their social and economic sustainability

18. 3. Limitation of resources
National University of
Malaysia
• Two fundamental truths
– 1. the earth is indeed the
only place to live that is now
accessible to us
– 2. Our resources are limited,
and while some resources are
renewable, many are not.

Two Major views on natural resources
– 1. Finding resources is not so much a problem as is
finding ways to use them (i.e. easy to find new
resources)
NO resource crisis
• Efficient and intelligent use of materials
– Use lightweight material to build a car
– New technology to save fuel
• We know more about extracting minerals than we did in the
past
– Find new resources faster
– Mining lower grade of minerals
• Recycling of resources can help us meet the needs of the
future.
28-Jan-14

20. National University of
Malaysia
– 2. A finite resources cannot support an
exponential growth of people forever. And we
are in a resource crisis due to:-• Improvements in medical technology contributing to
over population
• Ever increasing gross national product based on
obsolescence (design not to last long) and waste.
• The finite nature of the minerals

• Earth processes hazardous to people
– Flooding; earthquakes; volcanic; landslides; mudflows
• Must be recognized and avoided
• Reduce threat to human life and property
“Earthquakes do not kill, buildings do”
28-Jan-14

28. Hazardous earth processes
• Conflict between human vs nature
• Earth scientists / Engineers:
– identify potentially hazardous
processes
– make info available to
planners/decision makers
