ANIMALS-BASE OF OUR LIFE
Our needs-taming the animals
  • Our ancestors lived in forests. At first, their primary food was animals and tubers.
  • Later they started growing crops and doing different kinds of work.
  • During the course of time, for food, security and transport man started taming the animals to fulfill their needs.
  • The present day animals are their successors.
  • Since generations man has been using animals to fulfill his needs. The milk of cow and buffalo is used as food.
  • Similarly,ox and bull are used in agriculture.
  • We use some other animals also for our needs.

Animals for our needs
  • Have you ever seen a camel?
  • They are found more in Rajasthan. It is a desert region.
  • It is very difficult to walk across the sand in desert.
  • The people living in deserts travel on camels.
  • Some people from Rajasthan bring camels to our state and use them as 'fun-ride' for children and earn money for their livelihood.

Camel
Sheep is my wealth
  • Shepherds have to rear sheep, at the uplands and hills.
  • They have to take the sheep to the uplands early in the morning.
  • They should protect the lamb by carrying them on his shoulders. We can graze sheeps not only on the hills but also in the fields.
  • In summer, when grass is not available, they have to migrates to different places along with the sheeps for months.
  • They take a donkey with them to carry their cooking utensils and other things.
  • They stay wherever they find grass. Usually, the grass is available near the banks of streams and canals. Some times cheetahs, jackals and hyenas attack the sheep. Dogs protect them to some extent. There is a fear of snakes during night times.
  • Some farmers ask the shepherds to leave their sheep in their fields during the night.
  • If the flock of sheep stay in the fields during nights, their excreta overtime will become a fertilizer and is useful for the crops. As the farmers are benefited they, in turn give rice and vegetables to the shepherds. In this way, they help each other.
  • They sell the adult sheep whenever they gets a good offer. They does not sell the lambs. They clears the debts with the money they get and save some money.
Lingaiah sold 22 of his sheep at Rs.5000/- each. He also got an income Rs.4000/- on selling the excreta of the sheep and Rs. 2500/- on selling wool. He spent Rs.68,000/- on the sheep for medicines, vaccination, fodder and transportation for the whole year. How much money is left with Lingaiah ?

Problems of sheep rearing
  • Sheep rearers face many problems in their lives. Venkataiah and Kishan of Mahaboobnagar also have taken up sheep rearing as means of livelihood. They face many problems during famines. Let us know what is published about them in news papers!

Friends of farmer
  • Do you know that some small creatures also help farmers a lot? How?

Earthworm
  • Earthworm eat the waste products from fields. Soil become fertile with earthworm excreta.
  • Earthworm loosen the soil so that the roots of the plants get enough air. By this the plants grow well and the yield of the crop increases.
  • But we are dying due to the usage of pesticides.
Earthworm

Spider
  • Spider uses his mouth for secretion and make a thread. It knit the web with this thread.
  • Have you ever seen spider web?
  • The insects and mosquitoes which harm the crops get stuck in spiders web.
  • Thus, spider protect the crops from harmful insects. We are dying due to the usage of pesticides.

Spider

Ant
  • Ant walk on the plants in the fields. It eats the smaller insects and their eggs lying on the plants.
  • In this way, ant helps the farmers to avoid the use of pesticides.

Ant

Snake
  • Snakes help the farmers by swallowing the rats that eat the grains and destroy the fields.
  • Most of us are afraid of snakes and kill them wherever we seen them.
  • In fact, the snakes like king cobra (Nagu Pamu) Viper, Sea snake, Russell's Viper are poisonous and the other snakes are not poisonous.
  • Snakes try to protect themselves from people who try to harm.

Snake

Tykrograma
  • The scientists from the Institution of crops & Agricultural Research(I.C.A.R.) created tykrograma.
  • Tykrograma life span is only one week. It destroy the eggs of the enemy insects that infect the crops.

The other uses of animals
  • As you know that we get milk, eggs, meat etc., from animals. We use animals for transport also.
  • Which animals are useful to us and how? Look at this fan.

  • Peacock feathers
  • Do you know as how it is made? The tribal people make the fans with the fallen feathers of peacock and sell them in the fairs.
  • There are some industries. Which make buttons with the horns of ox. They export these to other countries also.
  • We get many products from animals.

products from animals
Needs and difficulties of animals
  • We need air,water,food and shelter to live. Besides these,living together, love,affection,sympathy kindness etc., are also important to us.
  • Other animals also need all these things, like us. These are basic needs.
  • Think, wheather we support animals to get their basic needs.
  • Are we taking care of animals when they are subjected to pain or are wounded,hungry,thirsty or suffering from cold, heat and rain? How do we feel when we are subjected to pain like them?

  • difficulties of animals
  • People are killing the elephants for their tusks. Tigers and deers get killed for their hides. They are hunting, capturing and eating many other animals and birds.

Decreasing animal population
  • When there was no man on the earth,only one animal species per year could extinct. This is quite natural.
  • But nowadays, one species is disappearing every 20 minutes.
  • Tiger is our national animal. Royal Bengal tiger is seen more in India and Bangladesh.
  • Once, there were thousands of tigers in the forests.
  • At present their number has decreased considerably in our country. It is a worrying thing that the number of Battameka pakshi, Kalivi kodi and Punganuru cow is decreasing day by day.

Vulture
  • The bird in the picture is a vulture. It's 2 feet in height. It is not seen in our state for some years.
  • If you find this in your area, you are requested to inform the Bio-dirversity Society of Telangana immediately.
  • It is interesting to know that the informers will be paid 2 lakh rupees as a reward.
  • Bio-diversity
    • Whose earth is this? Is it only for humans beings? This earth is for different species like trees, animals, birds, fish etc.
    • The nature provides sufficient food and water to all living things. Animals take their daily food according to their requirement only. They don't grab and store from nature.
    • But the man rules the world by saying "everything is mine"! He is using more than his genuine requirements.
    • He wants to enjoy all the natural wealth now itself. This is greed.
    • Gautama Buddha said that "Wants and greed make our life sorrowful". All living creatures have equal right to enjoy the natural resources on the earth.
    • Man is the only reason and responsible for pollution. Due to the mixing of pesticides, waste products and chemicals from factories with water and rivers many creatures that live in water are dying.
    • Think...what problems the animals and birds are facing due to the plastics invented by the modern man.The Cattle are dying by eating the plastic covers thrown by us.

    Bio-diversity-things to be done
    • Trees should be grown in the backyards of houses, school premises,streets & vacant places.
    • Trees should not be cut down. Reforestation should be our goal.
    • Animals and birds in our surroundings should be looked after with care, affection and love. Food should be given to them.
    • Lakes, ponds, rivers which give shelter to many animals and fishes should not be polluted.
    • We should not destroy the water animals by throwing plastic bags and other waste materials into the water.
    • The fuels like petrol, coal etc; and the pesticides should not be used indiscriminately, as this pollutes the environment. Either we should walk or use cycles.
    • Any kind of action which harms living creatures should be avoided & discouraged.
    • The habitats of the animals should not be destroyed in the name of development. If possible, they should be helped to live.
    • Form an animal protection committee at your school. Take an oath to protect the environment and animals.
    • Hunting wild animals is prohibited by the law. Find out more about this act from your elders and teachers and inform the particulars to all the village members & friends.
    • Prepare a poster saying that all animals and birds should be shown love and affection. Provide them water and food. Paste the poster at prominent places like your school and the village.
