The guide advises consumers to avoid purchasing items made from endangered species, such as beluga caviar, ivory, rhino horn, shahtoosh, pangolin and sea turtle leather, big cat furs, and tortoiseshell. It highlights the illegal nature of these trades and the ecological threats they pose, including the extinction of the Caspian Sea beluga sturgeon and the poaching of over 1 million pangolins over a decade. For certain items like exotic pets, coral, crocodile leather, and rare succulents, the guide recommends extreme caution, urging buyers to verify legality, permits, and sustainable sourcing to avoid supporting illegal wild-harvesting in regions such as Mexico and South Africa.

The document defines tipping points as critical thresholds where accumulated changes push a system into a new, often irreversible state. It highlights negative tipping points, such as the collapse of coral reefs, the shutdown of North Atlantic ocean mixing, and the die-back of the Amazon rainforest, noting that these can trigger a domino effect. Conversely, it describes positive tipping points as thresholds that accelerate beneficial changes, such as the growth of renewable energy and electric vehicles. WWF's approach involves protecting ecosystems, addressing drivers of environmental change, and ensuring equity in conservation efforts to prevent negative tipping points and foster positive ones.

The document describes the increasing scale and intensity of wildfires, driven by climate change and historical fire suppression practices, particularly in the United States. It highlights how fires release significant carbon stores, including 'legacy carbon', and disproportionately affect marginalized communities. To mitigate these risks, the author advocates for a combination of 100% clean energy transition, prescribed burns, fire-resistant construction, and equitable community engagement in land-use planning.

The document argues that food waste reduction is an accessible and cost-effective opportunity for schools and communities. It highlights that up to 40% of food produced globally is wasted, contributing roughly 10% of global greenhouse gas emissions. Through examples from the US, such as the Olympia School District and Montgomery County, it demonstrates that simple interventions like bulk milk dispensers and share-tables can reduce waste and save money. The text promotes a hierarchy of food waste solutions, prioritizing source prevention and human consumption over composting.

Groundwater constitutes nearly all of the world's liquid freshwater and is essential for drinking water, agriculture, and maintaining river flows. In the Rio Grande/Rio Bravo basin, groundwater is critically overdrawn and endangered by climate change and population growth, leading to initiatives like WWF-Mexico's nature-based aquifer recharge projects.

Bridget Berg, a former teacher at Palouse Prairie Charter School in Moscow, Idaho, implemented a semester-long expedition titled "The 6th Mass Extinction" for 5th grade students. The project integrated standards-based learning with real-world environmental threats, leading students to research biomes and threatened species. The expedition culminated in a public performance at The Kenworthy theater, featuring voiced poems and watercolor art created from the perspective of endangered species to combat student apathy and foster leadership in conservation.

Annette Maier, a teacher at Jefferson Middle School in San Gabriel, California, integrates WWF and Wild Classroom materials into her curriculum to educate students on biodiversity. Her approach includes symbolic animal adoptions, an endangered species project, and a 'Biodiversity Escape Room' activity. Students also participated in a live interaction with a WWF scientist and Mike Mitchell, the director of Kung Fu Panda 4, to learn about the connection between biodiversity, teamwork, and environmental protection.

The guide highlights that approximately 63 million tons of food are wasted annually in the United States, primarily in supermarkets, restaurants, and home kitchens. It advocates for three main actions to reduce environmental impact: shopping prudently through menu planning and freezing leftovers, increasing the consumption of fruits and vegetables to lower greenhouse gas emissions and resource use, and composting food scraps to avoid the emission of methane in landfills, which traps 24 times more heat than carbon dioxide.

The document outlines various household changes to reduce climate impact, highlighting that washing clothes in cold water uses about one-tenth of the energy of hot water and that LEDs use up to 90% less energy than incandescent bulbs. It notes that heating typically makes up 29% of utility bills and that reducing global food waste could lower human-caused greenhouse gas emissions by 6%-8%. Additionally, it provides statistics on water waste, such as a leaky faucet wasting over 3,000 gallons annually, and plastic waste in the US, where only 8.7% of over 42 million metric tons is recycled.

The Arctic region, covering parts of eight countries and including the 5.4 million square mile Arctic Ocean, is facing severe threats from industrial development and climate change. Warming in the Arctic is occurring up to four times faster than the global average, leading to shrinking sea ice that endangers ice-dependent species like polar bears and threatens to disrupt global ocean currents through glacier melt.

Schools in the US waste approximately 530,000 tons of solid food and 45 million gallons of milk annually, resulting in an estimated $1.7 billion in lost value. This waste generates CO2 emissions equivalent to over 400,000 cars driven for a year and wastes 20.9 billion gallons of water. To combat this, the WWF's Food Waste Warriors program provides educational resources and tools for food audits, while practical measures such as share tables and composting can reduce school food waste by up to 70%.

The document describes five animals that change their appearance: the Arctic fox and stoat change coat color based on weather and environment; the mimic octopus alters shape and color to resemble other marine animals; the American goldfinch changes feather color seasonally; and the monarch butterfly undergoes metamorphosis from larva to adult.

Blue whales are the largest animals to have ever lived, reaching lengths of 100 feet and weights of 200 tons. They are the loudest animals on Earth, using low-frequency calls reaching 188 decibels for communication and navigation. As filter-feeders, they consume up to 8,000 pounds of krill daily. While genetically distinct from fin whales, hybrid blue-fin whales exist. Populations remain depleted from 19th-century commercial whaling and currently face threats from ship strikes, pollution, and climate change, leading WWF to initiate the safeguarding of "blue corridors" for their migration.

WWF has created a Deforestation and Conversion Free (DCF) Implementation Toolkit to assist companies in moving from commitments to action, specifically for beef, soy, and leather sourced from the Amazon, Cerrado, and Gran Chaco. The toolkit aligns with the Accountability Framework and provides a three-step process: assessing current practices, planning milestones, and executing actions using a technical reference catalog. It is designed for various value chain actors, including brands, financial institutions, and traders, and has been utilized by BRF S.A. for its soy supply chain.

WWF analyzed 25 frameworks across the marine renewables, shipping, tourism, and coastal development sectors, finding that most address ocean health only tangentially or lack sectoral granularity. The report argues for a holistic approach to science-based targets based on three pillars: capabilities, collaboration, and communication, emphasizing the need to move beyond 'do no harm' toward restoration and regeneration.

The document describes El Niño as a natural Pacific Ocean cycle that is being strengthened and made more frequent by climate change. It highlights the resulting increase in coral bleaching, particularly around the Galápagos Islands, and the broader global risks including severe droughts in India and the Horn of Africa, and heavier rains in the United States. The text notes that the 2026 El Niño event is breaking temperature records, with NOAA predicting it will reach "very strong" levels. WWF is responding by using its Oceans Futures platform to mitigate fisheries conflict and restoring mangroves in countries such as Mexico, Colombia, and Ecuador to improve coastal resilience.

The document outlines a comprehensive approach to responsible travel, emphasizing the reduction of greenhouse gas emissions, the protection of biodiversity, and the support of local economies. It provides specific criteria for selecting sustainable destinations and travel companies, such as GSTC accreditation and Science Based Net-Zero targets, while offering practical advice on reducing plastic waste and respecting local cultures.

The Coca-Cola Company and WWF have partnered since 2007 to improve water stewardship, reduce greenhouse gas emissions, and transition to a circular economy for plastics. Key achievements include the restoration of over 5,462 hectares of wetlands along the Danube River, the protection of 200,000 hectares of wetlands in the Yangtze River basin, and the implementation of rainwater harvesting systems in Mexico. The partnership has also supported Coca-Cola in setting a science-based target to reduce absolute GHG emissions by 25% by 2030 from a 2015 baseline. In agriculture, 56% of priority ingredient volumes were sustainably sourced as of 2020, supported by certifications like Bonsucro for sugarcane. The partnership was renewed in August 2021 for three years to further build natural capital and climate resilience.

In the Northwest Pre-Caspian Region of Russia, rising temperatures and declining precipitation have dried up natural water sources, threatening the endangered saiga antelope, particularly during the calving period. To address this, a WWF-funded pilot project restored three abandoned Soviet-era artesian wells in the Stepnoi Wildlife Refuge in late 2018. The restoration doubled the water flow at these sites, which are now used by saiga, foxes, and wolves. The project aims to improve calf survival, reduce competition with livestock, and decrease poaching by keeping the antelope within the protected area. The saiga population in the area is estimated to have grown from 5,000 to 7,000 individuals, though further adaptation measures are required.

The guide outlines three primary actions to support bee populations: planting native wildflowers to provide a balanced diet, maintaining 'messy' areas of land to provide nesting habitats for solitary bees, and eliminating the use of systemic pesticides like neonicotinoids. It highlights that while honey bees are well-known, there are over 20,000 bee species globally, many of which are threatened by habitat loss, climate change, and agricultural chemicals.
