2. RIVERS

3. A river is a natural
flowing watercourse,
usually freshwater,
flowing towards an
ocean, sea, lake or
another river.
Rivers are very important natural
resources.Rivers carry water and nutrients to
areas all around the earth. Rivers drain
nearly 75% of the earth's land surface.

4. Humans use rivers for irrigation in agriculture, for drinking
water, for transportation, to produce electricity through
hydroelectric dams, etc. Each of these uses can affect the
health of a river and its surrounding ecosystems. Rivers also
play an important role in a variety of things, such as :_
A RIVER OTTER
Rivers provide excellent habitat
and food for many of the
earth's organisms. River deltas
have many different species of
wildlife. Insects, mammals and
birds use the delta for their
homes and for food.
RIVERS’ ROLE IN HABITAT

5. RIVERS’ ROLE IN FARMING
River valleys and plains provide
fertile soils. Farmers in dry
regions irrigate their cropland
using water carried by irrigation
ditches from nearby rivers.
RIVERS’ ROLE IN TRANSPORT
Rivers provide travel routes
for exploration, commerce
and recreation.

6. RIVERS’ ROLE IN ENERGY
GENERATION
River valleys and plains provide
fertile soils. Farmers in dry
regions irrigate their cropland
using water carried by irrigation
ditches from nearby rivers.
Rivers are very beautiful and wonderful resources. But,
Rivers are non-renewable resources. Non-renewable water
resources are groundwater bodies that have a negligible
rate of recharge on the human time-scale and thus can be
considered non-renewable.

7. Some major threats to rivers are:-
1.exploitation
2.fragmentation
3.habitat destruction
4.introduced species
5.climate vulnerability
We humans are polluting fresh
waters in rivers by throwing wastes
like wrappers, plastic bottles, cans
etc in the rivers. Besides this,
hazardous wastes from factories
are released into the rivers. Dirty
water containing chemicals is put
back in the river.

8. We can conserve rivers by practicing the following steps:-
*Turn off lights when not in use and unplug chargers.
Energy production requires water to cool thermal power
plants and for extraction, transport, and processing in
fuel production.
*Pick up trash and litter and toss it in the recycling or
garbage cans. Lots of trash is washed down storm
sewers and back to the rivers.
