Earth is made up of….

+ = environment

All living thing depend on each other and on non living things for survival
![Page 5: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/5.jpg)
Humans often disturb the balance of nature by their own irresponsible actions
Human made disasters
![Page 6: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/6.jpg)
pollution
![Page 7: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/7.jpg)
Air pollution
Smoke from vehicles and factories
Use of pesticide spray
![Page 8: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/8.jpg)
The effects of air pollution
![Page 9: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/9.jpg)
1.Health problems
Harms our lungs and cause breathlessness
Causes redness in eyes
![Page 10: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/10.jpg)
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
![Page 11: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/11.jpg)
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
![Page 12: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/12.jpg)
4. Global warming
![Page 13: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/13.jpg)
The heat from sun warms the earth
![Page 14: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/14.jpg)
They are some gases in earths atmosphere called green house gases
![Page 15: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/15.jpg)
These green house gases reflect some of the heat of sun back to the surface of the earth which
helps to keep it warm
![Page 16: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/16.jpg)
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
![Page 17: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/17.jpg)
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
![Page 18: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/18.jpg)

resources
Resources should be used carefully
![Page 54: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/54.jpg)
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
![Page 55: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/55.jpg)
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
![Page 56: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/56.jpg)
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
![Page 57: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/57.jpg)
How can we save our planet
![Page 58: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/58.jpg)
1.Reduce use of fossil fuels such as petroleum, while using natural gas so that
less smoke and particulate matter emits from vehicles
![Page 59: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/59.jpg)
2.Planting more trees and putting a ban on random cutting of trees and forests
![Page 60: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/60.jpg)
3. Building more national parks and reserved forests to protect the animals
and plants
![Page 61: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/61.jpg)
4. Developing other source of energy use like wind, water, solar etc
![Page 62: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/62.jpg)
Building of engine that use fuel more efficiently
![Page 63: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/63.jpg)
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
![Page 64: Saving our planet /ICSE 5th class syllabus](https://reader034.fdocuments.in/reader034/viewer/2022051404/58efc9681a28ab5e528b45a3/html5/thumbnails/64.jpg)
