NGOs say the lack of world leaders at COP15 risks dampening momentum at the talks.
High-stakes biodiversity talks opened in Montreal Wednesday, amid calls for a "peace pact with nature" to save the planet's species and ecosystems from irreversible human destruction.
Delegates from across the world gathered for the December 7-19 meeting to try to hammer out a new deal for nature: a 10-year framework aimed at saving Earth's forests, oceans and species before it's too late.
"It's time for the world to adopt an ambitious biodiversity framework — a true peace pact with nature — to deliver a green, healthy future for all," UN chief Antonio Guterres told reporters.
Inger Andersen, head of the UN Environment Programme (UNEP), urged negotiators to land a strong framework for nature. "Nature and biodiversity are dying the death of a billion cuts and humanity is paying the price for betraying our closest friend," she said.
The Ukraine conflict cast a shadow over early exchanges.
Representatives from the European Union and New Zealand, also speaking on behalf of other countries including the United States, slammed Russia for the environmental destruction brought about by its invasion.
Ukraine has said tens of thousands of dead dolphins have washed up on the Black Sea, blaming military sonar used by Russian warships for the disaster.
Russia's representative fired back that the meeting was an inappropriate forum and accused its critics of hypocrisy for not raising previous conflicts — such as Iraq and Afghanistan — in the context of talks on nature.
Outside the downtown convention centre where the talks were hosted, some 150 activists dressed in black demonstrated against what they called the hypocrisy of the summit, as riot police watched on.
Draft targets for the 10-year framework include a cornerstone pledge to protect 30 percent of the world's land and seas by 2030, eliminating harmful fishing and agriculture subsidies and tackling invasive species and reducing pesticides.
Finance is among the most divisive issues, as developing nations are demanding increased funding for conservation.
Earlier this year, a coalition of nations called for wealthy countries to provide at least $100 billion annually — rising to $700 billion a year by 2030 — for biodiversity.
Guterres told AFP: "It must be recognised that without a significant mobilization of funding, of various origins but with a substantial volume, developing countries will not be able to meet the requirements of biodiversity conservation.
"It should not be forgotten that most of the world's biodiversity wealth exists in developing countries."
The sticky issue of biopiracy is also causing roadblocks, as many mainly African countries demand that wealthy nations share the benefits of ingredients and formulas used in cosmetics and medicines derived from the Global South.
Implementation has emerged as another sticking point in recent days, with disagreements over how to ensure any final deal is put into practice — unlike its predecessor agreed in 2010.
The meeting, delayed two years because of the Covid-19 pandemic, follows crucial climate change talks in Egypt last month that ended with little headway on reducing emissions and scaling down the use of planet-warming fossil fuels.
China is chair, though it is being hosted in Canada because of Beijing's long-standing zero-Covid policy.
NGOs say the lack of world leaders at COP15 risks dampening momentum at the talks and could scupper an ambitious settlement.
Some 30 NGO observers marched in the corridors of the convention centre, waving placards that read "Stop the collapse" and " Act now for a positive world."
Patricia Zurita, CEO of BirdLife International, told AFP "the conversation is not addressing the urgency, not pushing for the ambition that we really need to have to make sure that our planet is going to be a place where we can survive."
The talks come amid dire warnings from scientists that the world is facing its biggest mass extinction event since the dinosaur age, with more than one million species at risk.
Human activity has decimated forests, wetlands, waterways and the millions of plants, animals and insects that live in them, with half of global GDP in some way dependent on nature.
