Q.Which of the following statements about environment are correct ?

The World Social Forum emerged at the turn of the millennium as a direct counterpoint to the World Economic Forum held annually in Davos, Switzerland. While Davos brought together political leaders, corporate executives, and financial elites to discuss global economic integration, a coalition of civil society organizations, trade unions, and social movements felt the need for an alternative space—one that would center the voices and concerns of those often excluded from or harmed by neoliberal globalization.

Brazil became the natural home for this inaugural gathering. The country was experiencing a moment of political ferment, with the Workers' Party gaining strength and progressive movements mobilizing around issues of land reform, workers' rights, and economic justice. Porto Alegre, the capital of Rio Grande do Sul state, had already earned international recognition for pioneering participatory budgeting—a democratic experiment that allowed ordinary citizens to decide how public funds should be spent. The city's progressive municipal government and its tradition of grassroots democracy made it an ideal symbolic and practical venue.

In January 2001, thousands of activists, intellectuals, and representatives from non-governmental organizations converged on Porto Alegre for what would become an annual gathering. The forum's slogan—"Another World Is Possible"—captured its animating spirit: a rejection of the idea that corporate-led globalization was inevitable or desirable, and an affirmation that alternatives rooted in social justice, environmental sustainability, and democratic participation could be imagined and built. …

Environmental concerns have become an undeniable and central aspect of global politics. Issues like climate change, biodiversity loss, and transboundary pollution do not respect national borders, making international cooperation essential. This necessitates that nations engage in diplomacy, negotiate treaties, and form alliances to address these shared challenges, thereby integrating environmental matters deeply into the fabric of global political discourse and policy-making.

A landmark event in this integration was the United Nations Conference on Environment and Development (UNCED), popularly known as the Earth Summit. This pivotal conference was indeed held in Rio de Janeiro, Brazil, in June 1992. It brought together leaders from across the world to discuss pressing environmental issues and sustainable development strategies.

The Earth Summit was organised by the United Nations itself, underscoring the global body's recognition of the urgency and scale of environmental challenges. The conference resulted in key agreements such as Agenda 21, a comprehensive plan of action for sustainable development, and the Rio Declaration on Environment and Development, which outlined principles for nations to follow. …

The global commons — those parts of the planet that fall outside national jurisdiction, such as the high seas, the atmosphere, Antarctica, and outer space — belong to no single nation yet sustain all life. The Earth Summit of 1992 in Rio de Janeiro was a landmark moment when the world came together to address this shared inheritance. But beneath the lofty declarations lay a deep divide between the industrialised North and the developing South.

Northern countries, having already achieved high levels of industrialisation, began to worry about the environmental consequences of growth — climate change, ozone depletion, loss of biodiversity — from the 1970s onward. Their citizens, with basic needs largely met, could afford to prioritise "luxury" concerns like preserving rainforests or cutting carbon emissions. By the time of the Earth Summit, the North pushed hard for binding commitments on environmental protection, framing the global commons as a fragile trust that all nations must safeguard.

Southern countries, by contrast, saw the issue through a different lens. For them, the most pressing problem was poverty, not pollution. They argued that the North had grown rich by freely exploiting the global commons — burning fossil fuels, overfishing oceans, emitting greenhouse gases — and now, having prospered, wanted to pull up the ladder. The South feared that strict environmental rules would stifle their own development, keeping them poor forever. At the Earth Summit, developing nations insisted on "common but differentiated responsibilities" — a principle that acknowledged the North's historical role in degrading the commons and placed a heavier burden on it to act first. …

The notion that Northern countries care more about global commons than Southern countries misreads the history of environmental diplomacy. Global commons—the atmosphere, oceans, Antarctica, outer space—belong to no single nation, and their degradation affects everyone. Yet the politics of who should bear responsibility for protection has always been contentious, and Southern countries have consistently championed their preservation, albeit on terms that acknowledge historical inequities.

Northern industrialized nations did indeed raise the alarm on issues like ozone depletion and climate change, often framing environmental protection as a universal imperative. But Southern countries have never been passive or indifferent. Their concern has been equally strong, though expressed through a different lens: they argue that the North, having industrialized first and contributed disproportionately to environmental damage, cannot now impose equal burdens on countries still developing. This is not apathy; it is a demand for justice within the framework of protecting the commons.

A powerful example is the 1992 Earth Summit in Rio de Janeiro. Southern countries, led by India, China, and the G77 bloc, were instrumental in embedding the principle of common but differentiated responsibilities into the climate convention. They insisted that while all nations share the atmosphere, the obligation to cut emissions must reflect who polluted it historically. India's stance was unequivocal: protect the global commons, yes, but do so fairly. The South did not reject environmental action—it rejected an arrangement that would lock developing nations into poverty while the North retained its industrial advantage.

The Earth Summit, formally known as the United Nations Conference on Environment and Development (UNCED), was held in Rio de Janeiro, Brazil, in June 1992. It was a watershed moment in international relations because it brought together an unprecedented number of world leaders — over 100 heads of state — along with thousands of delegates from 178 countries. Before 1992, environmental concerns had certainly been discussed at various international forums, such as the 1972 Stockholm Conference on the Human Environment, but those earlier efforts were fragmented and lacked the political weight and binding commitments that the Earth Summit achieved.

What made the Earth Summit truly historic was its success in consolidating environmental issues into the mainstream of global politics. For the first time, the world's nations agreed that environmental degradation was not a separate, niche concern but was deeply intertwined with economic development, poverty, and international security. The summit produced several landmark outcomes that gave concrete form to this new consensus: the Rio Declaration on Environment and Development, which set out 27 principles guiding sustainable development; Agenda 21, a comprehensive global action plan for sustainable development into the 21st century; and the legally binding conventions on climate change and biodiversity.
