Q1.
Write your observations on how the life around a coastal region differs from the life in a desert.
Answer

The two places are almost opposite. The coast has plenty of water; the desert has very little.

CategoryCoastal region (Puri, Odisha)Desert (Rajasthan)
WaterThe sea is right there, and it rains a lotVery little rainfall; water is stored in tankas
LandFlat sandy shore beside the seaDry sand dunes stretching far away
TreesCoconut and other palms, tall and greenCactus, khejri and babool, short and thorny
AnimalsSea turtles, crabs, dolphins, starfish, fishCamels, lizards, wild cats, pythons, eagles
WorkMany people depend on fishingRearing camels and goats, craft work, farming where water reaches
HousesSloping thatched or tiled roofs to throw off rainMud walls and thatched roofs, with a tanka for water
FoodDalma, pakhala, chhena poda, rasagolaDal-bati-churma, ker sangri
TravelBoats on the water, roads on landCamels and camel carts over the sand
Why they differ: water decides almost everything. Where there is plenty of water, people fish, tall trees grow and roofs must throw off rain. Where water is scarce, people store it, plants stay small and animals must manage with very little.
Q2.
Why is it important to keep our beaches clean?
Answer

A clean beach keeps sea creatures, people and work safe.

  • Animals stay safe. Turtles, dolphins and fish swallow plastic bags by mistake and fall ill or die.
  • People stay healthy. Rubbish and broken glass on the sand can cut feet and spread illness.
  • The sea stays clean. Waste on the sand is carried into the water by the waves.
  • Work goes on. Fishermen get more fish from clean water, and visitors keep coming, so shopkeepers and artists earn.
  • Play and art need clean sand. Sand castles, sand art and shell collecting are only possible on a clean beach.
Why it is our job: the sea cannot clean itself of plastic. Whatever we leave on the beach stays there or goes into the water, so the only way to keep it clean is to carry our waste back with us.
