(iv) What is sustainable development?
Ans: Sustainable development is about using resources wisely. It means using what we need now, but also saving for the future. It is a balance between consumption and conservation. Simply put, it ensures that we meet our current needs without compromising the ability of future generations to meet their own needs.
Q2. Tick the correct answer.
(i) Which one of the following does not make a substance a resource?
(a) Utility
(b) Value
(c) Quantity
Ans: (c)
Quantity does not determine whether a substance is considered a resource or not. A resource is defined by its utility and value, which means it should be useful and have worth. However, the quantity of a substance does not determine its resource status. Even if a substance is abundant in quantity, it may not be considered a resource if it lacks utility or value.
(ii) Which one of the following is a human-made resource?
(a) Medicines to treat cancer
(b) Spring water
(c) Tropical forests
Ans: (a)
A human-made resource is something that is created or produced by human beings for a specific purpose. Medicines to treat cancer are developed through scientific research and manufacturing processes. They are intentionally produced to address the health issue of cancer. In contrast, spring water and tropical forests are natural resources, not created by human beings.
(iii) Complete the statement.
Non-renewable resources are
(a) those which have limited stock
(b) made by human beings
(c) derived from non-living things
Ans: (a)
Non-renewable resources are resources that cannot be replenished or renewed within a human timeframe once they are depleted. They have a limited stock or finite availability in nature. Examples of non-renewable resources include fossil fuels like coal, oil, and natural gas. These resources are formed over millions of years and cannot be replaced in a short span of time.
