1. What is meant by environment?
Environment is defined as the total planetary inheritance and the totality of all resources. It encompasses all living and non-living things that exist naturally. The environment includes biotic elements like birds, animals, plants, forests, and fisheries, as well as abiotic elements such as air, water, land, rocks, and sunlight. These biotic and abiotic components influence each other, creating a complex web of interactions.
2. What happens when the rate of resource extraction exceeds that of their regeneration?
When the rate of resource extraction exceeds that of their regeneration, it leads to several negative consequences, resulting in an environmental crisis. The environment has a certain carrying capacity, which means it can perform its functions effectively as long as the demand on these functions is within its limits. This includes the balance between resource extraction and regeneration, as well as the generation and assimilation of wastes.
Here are the key points highlighting the consequences of exceeding the environment’s carrying capacity:
1.
Failure in Life Sustenance: The environment fails to perform its vital function of life sustenance. This is because the resources are being used up faster than they can regenerate, and the waste generated is more than what the environment can assimilate.
2.
Resource Extinction: Many resources become extinct due to overuse. This is particularly true for non-renewable resources, which once used up, cannot be replaced.
3.
Environmental Degradation: The wastes generated exceed the absorptive capacity of the environment, leading to pollution and degradation of natural habitats.
4.
Economic Consequences: The depletion of natural resources and the costs associated with environmental degradation lead to economic challenges. There is a need to spend significant amounts on technology and research to find new resources and ways to mitigate environmental damage.

SUGGESTED ADDITIONAL ACTIVITIES
1. Suppose 70 lakh cars are added every year to the roads of metropolitans. Which type of resources do you think are undergoing depletion? Discuss.
If 70 lakh cars are added every year to the roads of metropolitans, several types of resources are undergoing depletion:
1.
Fossil Fuels: Cars primarily run on fossil fuels such as petrol and diesel. With the addition of 70 lakh cars annually, the consumption of these fuels would significantly increase, leading to the rapid depletion of fossil fuel reserves. Fossil fuels are non-renewable resources, meaning they do not replenish at the same rate as they are consumed, and once depleted, they cannot be replaced.
2.
Air Quality: The burning of fossil fuels in cars releases various pollutants such as carbon monoxide, nitrogen oxides, and particulate matter into the atmosphere. With the increase in the number of cars, air pollution levels would rise, degrading air quality. Clean air is a vital natural resource, and its degradation affects human health, ecosystems, and the climate.
3.
Water Resources: The manufacturing process of cars requires a significant amount of water. Additionally, the maintenance of cars, such as washing, also consumes water. With the production and maintenance of 70 lakh additional cars each year, water consumption would increase, contributing to the depletion of freshwater resources.
4.
Raw Materials: Cars are made from various raw materials such as steel, aluminum, rubber, and plastics. The increased production of cars to meet the demand would lead to the depletion of these raw materials. Mining and extraction of metals and other materials also have environmental impacts, including habitat destruction and soil degradation.
5.
Land: The addition of a large number of cars requires expanded infrastructure such as roads, parking lots, and service centers. This leads to the conversion of natural habitats and agricultural land into urban and industrial areas, resulting in the depletion of land resources and loss of biodiversity.
In summary, the addition of 70 lakh cars annually to the roads of metropolitans would lead to the depletion of various resources including fossil fuels, air quality, water resources, raw materials, and land.
