SCIENCE PROJECT Travelling enhances your horizon but our dependence on non renewable resources for our comfort is having an adverse effect on the mother Earth. It’s high time that the development in the field of tourism needs rethinking and our design of hotels needs to be sustainable and environment friendly. As a nature lover, you care for the Earth and there are many travelers like you who would love to join hands with you. Design a hotel for likeminded travelers and advertise it. Mode of advertisement: A brochure Few ideas to be incorporated: Greenery, managing kitchen and garden waste, sewage and pool water, judicious use of non renewable resources and etc. SCIENCE Section -A (Physics) Q.1.
