Answer:
Claim: Yes, it is true that human self-interest is the driving force behind all environmental problems.
Evidence: The Increasing rate of global warming is the best evidence for the claim.
Reasoning: This is so because of human self-interest such as buying a car, burning of fossil fuels in industries, use of plastic, cutting trees, and hunting or poaching result into all environmental problems such as air pollution, deforestation, and endangered wildlife which leads to global warming.
