CBSE Class 10 IT – Unit 5 Green Skills II Notes for 2024-25
The environment around us affects all aspects of our life; and all our day to day activities also affect the environment.
Sustainable Development
Sustainable development is the development that satisfies the needs of the present without compromising the capacity of future generations, guaranteeing the balance between economic growth, care for the environment and social well-being.
- Needs of Present
- Needs of Future
Importance of Sustainable Development
With increasing population & income, the consumption of goods is increasing day by day. This has led to increase in production & utilization of natural resources, which are required for producing goods.
Since most of the natural resources are scarce, therefore, careful utilization of resource is necessary.
- Population
- Environment Issues
Problems related to Sustainable Development
There major problems related to sustainable development are :
- Food
- The amount of rich, fertile land needed to grow crops, such as wheat, rice, etc., it becoming less as we are using up more and more land for other purposes. Soil nutrients are also getting depleted and lots of chemicals are spoiling the soil due to use of chemical fertilizers.
- Water
- We use fresh water from rivers and ponds for drinking & cleaning but dump garbage into them. The rivers and ponds are getting polluted. This way after several years, we will have no clean water for our use.
- Fuel
- We are using a lot of wood from trees as fuel and for construction of homes and furniture. As more and more trees are being cut, it is affecting the climate of the place. Extreme weather conditions, such as floods, extreme cold or heat, are seen in many places, which affect the people living there.
Solar Power
An environmental friendly way for production of power is using solar energy or energy from the sun which is unlimited. – Gujarat Solar Park
Sustainable development include :
- Reducing excessive use of resources.
- Recycling and reuse of waste materials.
- Planting more trees.
- Using more environment friendly material or biodegradable material.
Sustainable Development Goals
The sustainable development goals (SDGs) are a universal call of action to end poverty, protect the planet & ensure that all people enjoy peace & prosperity.
The SDGs were launched at the United Nations Sustainable Development Summit in New York in September 2015.
- End Poverty
- Protect Planet
- Peace
Sustainable Development Initiatives
When plastics were banned by the municipal corporation of Mangalore, Mr Ashwath Hegde found eco-friendly alternative. He made a 100% bio-degradable bag which can dissolve in hot water & decompose in natural environment. This is now being used in many countries and is going to help the environment.
Another innovative idea was to stop the use of plastic spoons, forks, etc. Narayana Peesapaty made edible cutlery made out of a grain these spoons can be eaten and even if they are not eaten they will easily decompose in the soil enriching it.
Sustainable Processes
Sustainable Processes are being used to help preserve the environment.
- Organic Farming :
- Organic farming is where farmers do not use chemical pesticides & fertilizers to increase their production.
- They use organic and natural fertilizers, such as cow dung to help in growing crops.
- Vermi Composting :
- Vermi – Composting is a natural process that employs specific species of worms to decompose organic matter like food waster and yard trimmings, transferring it into a nutrient-rich fertilizer called Vermi-compost, which enhances soil quality and support plant growth.
- Rain Water Harvesting :
- Rainwater Harvesting involves collecting water from rooftops and other surfaces and storing it in tanks or containers for future use, reducing reliance on traditional water sources and promoting sustainability.
