The document presents information on the environment of Bangladesh. It discusses key aspects of Bangladesh's physical environment including seasons, agriculture, forests, and rivers. It notes that agriculture is the most important sector of Bangladesh's economy and heavily depends on weather conditions. Rice is the staple food and jute is the main cash crop. The country has six seasons - summer, rainy season, autumn, late autumn, winter, and spring. Urban and rural environments are also compared, noting factors like population density, lifestyle, occupation, and connection to nature. The impacts of unplanned urbanization on the environment are then outlined, such as loss of ecosystems, pollution, waste, and carbon emissions.

3. What is
Environment ?
The environment is defined as the whole
physical and biological system surrounding
man and other organisms along with various
factors influencing them. The factors are
soil, air, water, light, land, animals, plants,
temperature etc.

4. Components of Environment
 Physical Atmosphere
Hydrosphere
Lithosphere
 Biological Abiotic
Biotic
 Cultural Society
Economy
Politices

7. Six Seasons of Bangladesh
There are six seasons in bangladesh.They
are summer,rainy-seasion,autumn,late-
autumn,winter and spring. Tow months
make a seasion. Each seasion has it's own
features.
Description of the seasons:
☞Summer
☞The rainy-season
☞The autumn
☞Late-autumn
☞Winter
☞Spring

8. Does Bangladesh really have six Seasons?

10. Agriculture
1. Contributes 16.3% in the national GDP
2. Empowers 63% of the population
3. 70.3% of Agricultural land
Agriculture depends on environment for its existence
Rivers
1. Commercial Centre's
2. Travel routes
3. Alluvial soil
Rivers plays important part in water cycle
Forests
1. Works as shield for us
2. Protects us from natural calamities
3. Protects soil from erosion

12. Definition of Urban
The term urban simply refers to the region or area
which is densely populated and possess the
characteristics of the man-made surroundings. The
people residing in such area, are engaged in trade,
commerce or services. In this settlement, there is
high scale industrialization that results in better
employment opportunities.

13. Definition of Rural
We define the term ‘rural’ as a region located on the
outskirts. It refers to a small settlement, which is outside
the boundaries of a city, commercial or industrial area. It
may include, countryside areas, villages or hamlets, where
there are natural vegetation and open spaces. There is a
low density of population in such area. The primary source
of income of the residents is agriculture and animal
husbandry.

14. Differences Between Rural and Urban
Environment
 Nature conversation
 Six seasons
 Pollution
 Diseases
 Dependency
 Toxic Chemical
 Solid waste disposal (appliances, bottles, cans and
plastic etc).

15. Key Differences Between Urban and Rural
 The life in urban areas is fast and complicated, whereas rural life is simple and relaxed.
 The Urban settlement includes cities and towns. On the other hand, the rural settlement
includes villages and hamlets.
 There is greater isolation from nature in urban areas, due to the existence of the built
environment. Conversely, rural areas are in direct contact with nature, as natural elements
influence them.
 Urban people are engaged in non-agricultural work, i.e. trade, commerce or service
industry. In contrast, the primary occupation of rural people is agriculture and animal
husbandry.
 Population wise, urban areas are densely populated, which is based on the urbanization,
i.e. the higher the urbanization, the higher is the population. On the contrary, the rural
population is sparse, which has an inverse relationship with agricultures.
 Urban areas are developed in a planned and systematic way, according to the process of
urbanization and industrialization. Development in rural areas is seldom, based on the
availability of natural vegetation and fauna in the region.

16. Impacts of Unplanned Urbanization on Environment
What is Urbanization?
Urbanization describes both growing cities and population shifts away from rural
living. Urbanization is the movement of people from the country to towns and
cities. The term also refers to the expansion of cities, i.e., growth of urban areas.
Urbanization has occurred many times in the past in different civilizations.
However, the current migration is occurring on a global scale. Today’s shift from
urban areas to cities and towns started in the industrial revolution.
Urbanization and Environment
Urban populations interact with their environment. Urban people change their
environment through their consumption of food, energy, water, and land. And in
turn, the polluted urban environment affects the health and quality of life of the
urban population.

17. Environmental Problems of Urbanization
 The loss of natural ecosystems
 Waste
 Urban runoff
 Isolation of wildlife and plant populations
 An increase in human-wildlife conflicts
 Loss of connectedness to nature
 Migration and Population growth

18. Continued…..
 Carbon emission
 Deforestation

19. Pollution
