A group of researchers is discussing the causes and effects of climate change during a conference. They aim to pinpoint the accurate relationship between a specific human activity and its consequent impact on the environment. Which scenario correctly identifies a human activity and its corresponding impact on the environment?
Q.2
Among the listed pollutants, which specific element poses the most significant risk to global water quality, often contributing to detrimental algal blooms?
Q.3
A country is considering expanding its nuclear energy capacity. Which of the following key environmental considerations they should address before making a decision?
1. Proper disposal of radioactive waste and ensuring plant safety 2. Promoting wildlife conservation in the vicinity of nuclear plants 3. Increasing water usage for cooling reactors
Q.4
A farmer observed that the soil in his fields was becoming increasingly dry, even after heavy rainfall. The farmer suspected that the dry soil was due to increased runoff, preventing water from infiltrating the ground. Which of the following practices could help the farmer improve soil moisture?
A. Tilling the soil to increase its water-holding capacity B. Planting cover crops to protect the soil from erosion C. Creating channels and other structures to slow down runoff
Q.5
