Q1: What is the most pressing environmental issue today?

I think climate change is the frame around everything else — biodiversity loss, ocean acidification, extreme weather — they're all connected. The frustrating thing is that we've known the problem for decades, and the solutions aren't particularly mysterious. What's missing is collective will. We continue to treat the climate as an externality rather than a foundation. That said, there are reasons for cautious optimism: renewable energy costs have fallen faster than even experts predicted.

Q2: Is it the responsibility of individuals or governments to solve environmental problems?

Both, but governments have to lead. Individual choices matter — what we buy, how we travel, what we eat — but the system is stacked against sustainable choices in so many ways. Public transport, building codes, carbon pricing: those are structural changes only governments can make. Relying on individual consumer choices lets governments off the hook. That said, public pressure is what forces governments to act, so individual action and collective action aren't separate.

Q3: Do developed countries have a greater responsibility for the environment?

Absolutely, and this is where international negotiations often break down. The developed world industrialised over two centuries by burning fossil fuels — that accumulated carbon is the main driver of current warming. Developing countries argue, fairly, that it's unfair to ask them to forgo the growth path that rich countries took. The honest answer is that developed nations owe both emissions reductions and climate finance to the Global South. This isn't charity; it's debt.

Q4: Can economic growth and environmental protection coexist?

They can, but it requires redefining what we mean by growth. The old model — GDP as the only metric — is fundamentally incompatible with planetary boundaries. But there's nothing inevitable about endless material throughput. Growth in services, in wellbeing, in efficiency — those don't require consuming more. The challenge is political: the industries that profit from the old model still have enormous lobbying power. The transition is possible; it just isn't automatic.
