Short answer: approaches have shifted from local, reactive fixes and resource-extraction attitudes to more preventive, science-based, systemic, and multi-level strategies that emphasize sustainability, market and policy instruments, international cooperation, social equity, and new technologies. Below is a concise timeline and the main ways approaches have changed.

1) Broad historical timeline
- Before industrialization: local resource-use norms, customary conservation (e.g., sacred groves, seasonal hunting); little scientific environmental management.
- 19th–early 20th century: conservation and preservation movements (national parks, species protection) in response to visible degradation from logging, hunting and early industry.
- 1960s–1970s: environmental movement and regulation—public awareness grows after events and books (Silent Spring, smog crises); modern environmental laws and institutions (e.g., Clean Air/Water Acts, EPA), focus on pollutants and end-of-pipe controls.
- 1980s–1990s: environmental economics, internationalization—market instruments (pollution permits, user fees), Rio Earth Summit (1992), beginnings of sustainable development framing and global treaties.
- 2000s–2010s: climate change becomes central; integrated approaches (ecosystem services, biodiversity mainstreaming); growth of green technology, corporate social responsibility and voluntary standards; Paris Agreement (2015).
- 2010s–present: emphasis on decarbonization, circular economy, nature-based solutions, resilience, environmental justice, and large-scale finance shifts (green bonds, ESG investing). Greater attention to adaptation, equity, and systemic drivers (consumption, supply chains).

2) Major shifts in approach (what changed)
- From reactive to preventive: moving upstream to prevent impacts (clean production, design for environment) rather than only treating waste.
- From single-issue to systems thinking: recognizing links among climate, biodiversity, land use, health, and economy; integrated policy-making.
- From national/local to global governance: treaties (Montreal, Kyoto, Paris), global targets (SDGs), cross-border finance and supply-chain rules.
- From command-and-control to mixed instruments: complementing regulation with market mechanisms (cap-and-trade, carbon pricing), subsidies for clean tech, information tools and nudges.
- From top-down expertise to multi-stakeholder governance: inclusion of NGOs, private sector, Indigenous peoples, local communities, and public participation.
- From technology-centric to combined tech + nature-based solutions: renewable energy and efficiency plus ecosystem restoration and conservation.
- From singular economic goals to sustainability and equity: embedding social justice and intergenerational equity into environmental policy (environmental justice, Just Transition).
- From sparse data to data-driven management: satellite monitoring, remote sensing, citizen science, big data and modelling make detection and enforcement better.
- From ad hoc voluntary measures to standardized reporting and accountability: mandatory emissions reporting, corporate sustainability disclosure, internationally recognized metrics.

3) Drivers of these changes
- Science (e.g., climate science, ecology) demonstrating global risks and tipping points.
- High-profile environmental crises and their societal impacts.
- Economic shifts: renewable costs falling, clean tech opportunities, and the recognized economic cost of inaction.
- Social movements and public opinion pushing governments and companies.
- Globalization: cross-border pollution, global supply chains, and international diplomacy.
- Technological advances enabling new solutions and monitoring.

4) Examples
- Montreal Protocol (1987): successful international regulation that phased out CFCs—shows effective treaty, science + policy.
- Clean Air Act (U.S.) and similar laws: reduced air pollution through regulation and technology standards.
- EU Emissions Trading System and other carbon markets: using market incentives to cut emissions.
- Paris Agreement (2015): nationally determined contributions and emphasis on long-term goals and finance.
- Corporate ESG reporting, green bonds and sustainable finance mobilizing private capital.
- Rewilding projects, mangrove restoration, urban green infrastructure as nature-based approaches.

5) Criticisms and continuing challenges
- Implementation gaps: policies exist but are underfunded or poorly enforced.
- Greenwashing: voluntary corporate claims not always matched by action.
- Equity and responsibility: uneven historical emissions and capacity; developing countries need finance and technology.
- Insufficient pace: current policies often fall short of what science says is needed to meet climate and biodiversity targets.

6) Emerging directions
- Deep decarbonization and net-zero targets with carbon removal.
- Circular economy and product stewardship to reduce material flows.
- Integration of Indigenous knowledge and rights in management.
- Climate adaptation mainstreamed into planning and infrastructure.
- More stringent corporate accountability, standardized sustainability reporting, and nature-related financial risk assessment.

Bottom line: environmental approaches have evolved from local, reactive conservation and pollution control toward holistic, preventive, and multi-level strategies that combine regulation, markets, technology, nature-based solutions, and social equity — but success depends on implementation speed, finance, and political will.
