The document discusses environmental sustainability and the challenges posed by human activity. It defines sustainability as maintaining a balance between human use of natural resources and the ability of the environment to provide for current and future generations. Some threats to sustainability mentioned include pollution, climate change, loss of biodiversity, and depletion of natural resources due to population growth and consumption. The document advocates awareness, conservation efforts, and achieving smaller sustainability goals in areas like recycling, resources, water, energy, and waste management to help preserve the environment long-term.

2.  The study of the effects of natural and unnatural
processes, and of interactions of the physical
components of the planet on the environment.
 Continuous interaction between environment and
its other counterparts on the planet gives birth to
disharmony in the natural processes.

3.  Ability of systems and processes to flourish in a
natural conformity and at the same time remain
productive to mankind and other life forms.
 Maintaining this balance has become a challenge
due to advancement and progression of mankind.
 Awareness is the key to solving this problem.

4.  Sustainable environment is so vital because it will not
only affect us but our generations to come.
 In past human population was small and technology
and progression was also not so fast paced.
 Presently, our population growth rate is alarmingly
high .
 our avarice to make the most of what is available to
us is causing a major imbalance between provision
and consumption of resources.

5.  Defined as the natural assets of the earth such as
land, air, water, living organisms which provides the
basis of all human economic activity.
 Is responsible for supplying the raw materials to
mankind which enables them to survive and
improve their way of living.

6. Planet Earth is roughly dived into four main spheres.
 Lithosphere- crust and upper mantle
 Hydrosphere- all water sources
 Atmosphere- gaseous envelop
 Biosphere-all living matter

9.  Global Warming and Greenhouse Effect
 Depletion of Ozone Layer (cfcs)
 Pollution (air, water, land)
 Reduction In Biodiversity

11.  Main objective of sustainability is to conserve the
environment and its various features to facilitate
human beings of present and future.
 This objective can be achieved by attaining
smaller goals which will individually help in resolving
the core issue of environmental sustenance

12.  Recycling Sustainability
 Natural Resource Sustainability
 Water Sustainability
 Energy Sustainability
 Waste Management
