SAVING OUR PLANET
By Sarala
For her daughter Joshitha Sai
Earth is made up of….
+ = environment
All living thing depend on each other and on non living things for survival
Humans often disturb the balance of nature by their own irresponsible actions
Human made disasters
pollution
Air pollution
Smoke from vehicles and factories
Use of pesticide spray
The effects of air pollution
1.Health problems
Harms our lungs and cause breathlessness
Causes redness in eyes
2. Acid rain
Rain water consists of acid
When rain water mixes with pollutants in the air it becomes more acidic and comes as acid rain
3. Ozone hole
Ozone layer is protective gases in earths atmosphere which acts against harmful effects of sunrays
Many of the chemicals that are released in atmosphere harm the layer
some of them are so powerful that they make holes in the layer as a result harmful effects of sun rays are felt on our planet
4. Global warming
The heat from sun warms the earth
They are some gases in earths atmosphere called green house gases
These green house gases reflect some of the heat of sun back to the surface of the earth which
helps to keep it warm
How ever it is believed that burning of fossil fuels more and more green gases are added to atmosphere.
So the earth is getting warmer and this is called global warming
Result of global warming
World climate will change, ice caps in the polar region will melt, the sea levels will rise and health problems will increase
Water pollution
Water is essential for life
Yet we use it carelessly and often waste it
Water in rivers and streams get polluted by domestic or industrial waste
Effects of water pollution
Drinking of polluted water many diseases such as diarrhea
Soil pollution
Reasons for soil pollution
Bio degradable waste
Domestic waste Agricultural waste
Bio degradable waste mix with soil to form manure
Non bio degradable waste
Domestic waste Industrial waste
Effects of soil pollution
Soil pollution breeds germs and bacteria and causes many diseases
Save plants
Plants are our friends and help us in many ways
1. Plants keep the air clean
2.Trees effect rainfall of the place
3. Trees provide shelter for birds and animals
4. Trees provide us shade
5.Trees give us food , fruits and flowers
6.Plants are used as medicines
7. Trees provide wood
8. Trees bind top soil with their roots and prevent soil erosion
9. Trees help to make soil fertile when dead leaves decay
Deforestation
Reasons for mowing down of forests:
To use the land for habitation
Forests are mowed down for agriculture
Forest are cut down for resources
Grazing by animals also causes deforestation
aforestation
Protect animals
In what way animals help us:Farm animals provide us with milk and food
Animals provide us with wool and leather
Animals are also used as means of transport
Birds help to scatter the seeds of different plants
Pets provide security and companion ship
Many animals are in danger due destruction of forests
Extinction of pandas due to extinction of bamboo
Cattle choke on plastic covers and die
Shrinking of grasslands cause undernourishment for animals
In order to preserve wild life, especially endangered species of animals and birds, wild life sanctuaries and national parks has been built to protect these animals from poachers
Kanha national park in Madhyapradesh
Tiger reserves to protect tigers
resources
Resources should be used carefully
wastes Another way by which we spoil
environment is by the production of wastes in our daily life
We produce lot of domestic and industrial waste especially in cities
They add to the environment and make it dirty
Waste management
Reduce waste by avoiding plastic bags , foils, glass and tins that can not be used more than once
Reuse waste by using something more than once for different purpose
Waste management
Recycle non bio degradable items like glass, aluminum and metals to make various articles. Recycled paper is used by many people now
Replace non bio degradable items such as plastic bags with environmental friendly material like paper, jute or cloth bag
How can we save our planet
1.Reduce use of fossil fuels such as petroleum, while using natural gas so that
less smoke and particulate matter emits from vehicles
2.Planting more trees and putting a ban on random cutting of trees and forests
3. Building more national parks and reserved forests to protect the animals
and plants
4. Developing other source of energy use like wind, water, solar etc
Building of engine that use fuel more efficiently
Treating sewage, hospital and factory waste and emissions from factories and power stations before they are dumped in the water bodies or in the atmosphere
