Answers
Answer:
Green skills are those skills needed to adapt processes, services and products to climate change and the environmental regulations and requirements related to it. They include the knowledge, abilities, values and attitudes needed to live in, develop and support a sustainable and resource-efficient society. These skills are required in areas such as Renewable energy, climate change readiness, Wastewater treatment, Climate-resilient cities, Green construction, Solid waste management etc.
The 4R means Reduce, Reuse, Recycle and Restore.
(i) Reduce: We should reduce the use of non-biodegradable compounds that are harmful to us.
Example: Instead of using polythene bags we should give preference to paper bags.
(ii) Reuse: We should reuse the materials instead of dumping.
Example: Plastic bags can be reused to make decorative things.
(iii) Recycle: Non-biodegradable materials should be subjected to the recycling process.
Example: Plastic materials.
(iv) Recovery: If the waste remains after it is been reused and recycled, we can use it to generate energy at our waste-energy (EfW) plant. This is known as Recovery.
