Resources are vital for human survival as well as for maintaining quality of life. It was believed that resources are free gifts of nature. As a result, human beings used them indiscriminately. This led to the following major problems:-
  1. Depletion of resources for the greed of few.
  2. Accumulation of resources in a few hands which in turn, divided the society into rich and poor.

Similar UPSC Doubts

Many farmers use synthetic pesticides to kill infesting insects. The consumption of pesticides in some of the developed countries is touching 3000 grams/hectare. Unfortunately, there are reports that these compounds possess inherent toxicities that endanger the health of the farm operators, consumers and the environment. Synthetic pesticides are generally persistent in environment. Entering in food chain they destroy the microbial diversity and cause ecological imbalance. Their indiscriminate use has resulted in development of resistance among insects to insecticides, upsetting of balance in nature and resurgence of treated populations. Natural pest control using the botanical pesticides is safer to the user and the environment because they break down into harmless compounds within hours or days in the presence of sunlight. Plants with pesticidal properties have been in nature for millions of years without any ill or adverse effects on the ecosystem. They are easily decomposed by many microbes common in most soil. They help in the maintenance of biological diversity, of predators and the reduction of environmental contamination and human health hazards. Botanical pesticides formulated from plants are biodegradable and their use in crop protection is a practical sustainable alternative.On the basis of the above passage, the following assumptions have been made.1. Synthetic pesticides should never be used in modem agriculture.2. One of the aims of sustainable agriculture is to ensure minimal ecological imbalance.3. Botanical pesticides are more effective as compared to synthetic pesticides.Q.Which of the assumptions given above is/are correct?
