Final answer:
The cartoonist's perspective is that people's laziness is leading to the planet's destruction due to a lack of recycling efforts. The correct interpretation of the cartoon is 'a. that we are destroying our planet because we are lazy'.
Step-by-step explanation:
The cartoonist's perspective in the cartoon where a man is throwing a globe into a trash heap while commenting on recycling can be interpreted as a criticism of the lackadaisical attitude of individuals towards environmental conservation. The phrase 'Recycling? Bah! Too much work.' suggests that the cartoonist believes people are contributing to the destruction of the planet due to their laziness and unwillingness to undertake even small efforts like recycling that could have a significant positive impact. From this, we can infer that the correct answer to the student's question would be 'a. that we are destroying our planet because we are lazy'. The depiction of the man throwing the globe, which represents the Earth, into the trash implies a disregard for the planet and an indifference to the environmental harm caused by not recycling.
