types of
environmental
problems
• Climate Change
• Deforestation
• Water Pollution
• Air Pollution
• Loss of Biodiversity

3.

Climate
Change
There may be local drought and
floods, melting of Arctic ice and
retreat of glaciers, changes in the
distribution of climatic precipitation
and a decrease in the number of
days of comfortable weather

4.

Deforestation
This is a reduction in the
world's forest area.
This phenomenon is caused by
both natural and human
activity.
• Loss of biodiversity. Since
forests are the natural habitat
of many species, their
destruction affects the
survival of global biodiversity.
• Soil degradation. Forests
make soils richer in organic
matter and therefore more
resistant to weathering and
erosion.

5.

Water Pollution
• It is a process in which
harmful substances,
including chemicals
and microorganisms,
pollute a body of water
(for example, rivers,
lakes or oceans),
making it unsafe for
humans, animals and
plants.
• The main causes of
water pollution:
— industrial waste
— agricultural chemicals

6.

Air Pollution
this is the contamination of
the environment inside and
outside the premises with
any chemical, physical
substance or biological
agent that changes the
natural characteristics of
the atmosphere.

7.

Loss of Biodiversity
This is a gradual reduction in the diversity and richness of
species, ecosystems and living creatures
• Destruction of habitats. This is due to human activities
such as deforestation, urbanization, agricultural
development and infrastructure
• pollution of ecosystems. Industrial effluents, agricultural
effluents, plastic debris and air pollution harm
biodiversity by polluting reservoirs, soil and air

animal sanctuaries
are being built in the
world, nuclear energy
is being developed,
and hydro power
plants are being built
forests are being
restored and trees
are being planted
again

how we help protect the
environment: we clean up
garbage, help beavers
build a dam, sort
garbage,we recycle
garbage
