#BeatPlasticPollution and #WorldEnvironmentDay
June 5th, 2023, will mark the 50th anniversary of World Environment Day, which was established by the United Nations Environment Programme (UNEP) in 1973. This year, the event is anticipated to attract tens of millions of participants both online and through in-person activities, embodying the spirit of environmental advocacy.
Addressing plastic pollution
This year’s theme is focused on finding solutions to plastic pollution. The occasion underscores the consequences of actions and inaction taken by individuals, businesses, and governments in response to plastic pollution. It also highlights the pressing need to amplify these efforts and transition towards a circular economy. To assist in these efforts, a Beat Plastic Pollution Practical Guide is available, outlining steps to halt and reverse the detrimental effects of plastic pollution.
An urgent need
Our planet is in crisis, besieged by the overwhelming weight of plastic waste. Despite its numerous applications, plastic has become detrimental due to our dependence on single-use plastic products, which cause significant environmental and health issues.
As per the UN, globally, one million plastic bottles are bought every minute, up to five trillion plastic bags are used each year, and 400 million tonnes of plastic waste are produced annually. Approximately 36% of all plastic is used for packaging, including single-use items for food and beverage containers. Sadly, around 85% of these items end up in landfills or as unregulated waste. Less than 10% of the seven billion tonnes of plastic waste generated worldwide has been recycled. The most prevalent types of plastic waste found in the environment include cigarette butts, food wrappers, plastic bottles and caps, grocery bags, straws, and stirrers.
Environmental harm
Plastic waste can persist in the environment for centuries due to its durability and resistance to degradation. Nearly all single-use plastic products are manufactured from fossil fuels, contributing to the escalation of greenhouse gas emissions. Most plastic items merely break down into smaller microplastics, which can infiltrate the human body and accumulate in various organs. The impact of this phenomenon on human health remains largely unknown. Microplastics are now ubiquitous and are a part of the Earth’s fossil record. They have even led to the creation of a new marine microbial habitat, known as the “plastisphere.”
How you can help
Urge your local and national leaders to take decisive action by eliminating problematic plastic packaging, redesigning products for sustainability, and promoting transparency in sustainability information. Additionally, you can participate in beach or river clean-ups, shop sustainably, adopt a zero-waste lifestyle, advocate for change, choose sustainable fashion, and opt for plastic-free personal care products.

“As the world looks to the ongoing U.N. Biodiversity Conference to set the course for nature recovery, we simply cannot afford to fail,” said the head of the International Union for Conservation of Nature.
During the United Nations biodiversity summit in Montreal, an international conversation group on Friday highlighted how humanity is dangerously failing marine life with illegal and unsustainable fishing, pollution from agricultural and industrial runoff, and activities that drive up global temperatures.
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species now features 150,388 species, 42,108 of which face possible extinction. Of the 17,903 marine animals and plants on the list, more than 1,550 are at risk.
“Today’s IUCN Red List update reveals a perfect storm of unsustainable human activity decimating marine life around the globe. As the world looks to the ongoing U.N. Biodiversity Conference to set the course for nature recovery, we simply cannot afford to fail,” Bruno Oberle, the group’s director general, warned Friday. “We urgently need to address the linked climate and biodiversity crises, with profound changes to our economic systems, or we risk losing the crucial benefits the oceans provide us with.”
The primary aim of the 15th Conference of the Parties (COP15) of the Convention on Biological Diversity (CBD)—which is hosted by China but kicked off earlier in Canada this week due to Covid-19 restrictions—is the development of post-2020 global biodiversity framework (GBF).

A top priority for many parties to the treaty—along with the United States, which has failed to ratify the CBD over the past three decades but is still participating in the summit—is to protect 30% of lands and waters by 2030. However, as activists and Indigenous leaders from around the world have noted, there are serious human rights concerns regarding implementation of the 30×30 goal.
COP15 comes after the fifth round of discussions about establishing a U.N. treaty for the high seas, or the two-thirds of oceans outside territorial waters. Those August talks failed to produce an agreement—which, as Laura Meller of Greenpeace’s Protect the Oceans campaign warned at the time, “jeopardizes the livelihoods and food security of billions of people around the world.”
“While progress has been made, particularly on ocean sanctuaries, members of the High Ambition Coalition and countries like the USA have moved too slowly to find compromises, despite their commitments,” Meller continued. “Time has run out. Further delay means ocean destruction. We are sad and disappointed. While countries continue to talk, the oceans and all those who rely on them will suffer.”
Similarly, urgent warnings came with the update Friday. Ashleigh McGovern, vice president of the Center for Oceans at Conservation International, said that “with this devastating IUCN Red List update on the status of marine species, it is clear that business as usual is no longer an option.”
“Human activity has had devastating effects on marine ecosystems and biodiversity, but it can also be harnessed to drive action as a matter of survival, equity, and climate justice,” she added. “If we are to secure a new future for the world’s oceans and the essential biodiversity they harbor, we must act now.”

Jon Paul Rodríguez, chair of the IUCN Species Survival Commission (SSC), pointed out that “most of the Earth’s biosphere, 99% of all livable space on our planet, is underwater.”
“Humanity acts as if oceans were inexhaustible, capable of sustaining infinite harvest of algae, animals, and plants for food and other products, able to transform vast quantities of sewage and other pollutants that we pour in coastal areas, and absorb the CO2 generated by land-use change and burning fossil fuel,” he said. “This Red List update brings to light new evidence of the multiple interacting threats to declining life in the sea.”
According to the IUCN Red List, 20 of the 54 abalone species—some of the world’s most expensive seafood—are threatened with extinction.
“Abalones reflect humanity’s disastrous guardianship of our oceans in microcosm: overfishing, pollution, disease, habitat loss, algal blooms, warming, and acidification, to name but a few threats. They really are the canary in the coal mine,” said Howard Peters, a member of the IUCN SSC Mollusc Specialist Group and research associate at the U.K.’s University of York who led the abalone assessment.
“The most immediate action people can take is to eat only farmed or sustainably sourced abalones. Enforcing fishery quotas and anti-poaching measures is also critical,” Peters noted. “However, we need to halt the changes to ocean chemistry and temperature to preserve marine life including abalone species over the long term.”

The update also raised the alarm about dugongs, particularly in East Africa and New Caledonia. Populations of the large herbivorous marine mammals are threatened by fishing gear, oil and gas exploration and production, chemical pollution, and the destruction of seagrasses they rely on for food.
“Strengthening community-led fisheries governance and expanding work opportunities beyond fishing are key in East Africa, where marine ecosystems are fundamental to people’s food security and livelihoods,” said Evan Trotzuk, who led the region’s assessment.
Another focus of the list is the pillar coral in the Caribbean, given that its population has shrunk by more than 80% across most of its range over the past three decades.
Noting that it is just one of 26 corals now listed as critically endangered in the Atlantic Ocean, Arizona State University associate professor Beth Polidoro, Red List coordinator for the IUCN SSC Coral Specialist Group, said that “these alarming results emphasize the urgency of global cooperation and action to address climate change impacts on ocean ecosystems.”
Amanda Vincent, chair of the IUCN SSC Marine Conservation Committee, declared that “the awful status of these species should shock us and engage us for urgent action.”
“These magical marine species are treasured wildlife, from the wonderful abalone to the charismatic dugong and the glorious pillar coral, and we should safeguard them accordingly,” she added. “It is vital that we manage fisheries properly, constrain climate change, and reverse habitat degradation.”
Nodding to the conference, Jane Smart, director of IUCN’s Science and Data Center, said the update reinforces her group’s “urgent call for a post-2020 global biodiversity framework that will be ambitious enough to cease destruction of our life support system and catalyze the necessary action and change to secure life on this planet.”

Wetlands are areas of land that are covered by water, or have flooded or waterlogged soils. They can have water on them either permanently or for just part of the year.
Whether it’s year-round or seasonal, this period of water saturation produces hydric soils, which contain little or no oxygen. But this doesn’t mean that they are lifeless: Wetlands are full of unique water-loving plants and wildlife that have adapted to wet environments.
Wetlands can take many different forms, depending on the local climate, water conditions and land forms and features. For example, swamps are dominated by woody trees or shrubs. Marshes often have more grasslike plants, such as cattails and bulrushes. Bogs and fens are areas that accumulate peat – deposits of dead and partly decomposed plant materials that form organic-rich soil.
Trillions of dollars in ecological benefits
Wetlands are important environments for many reasons. They provide ecological services whose value has been estimated to be worth more than US$47 trillion per year.
For example, wetlands support very high levels of biodiversity. Scientists estimate that 40% of all species on Earth live or breed in wetlands.
Wetlands are critical homes or stopovers for many species of migratory birds. In the central U.S. and Canada, for example, wetlands in the so-called prairie pothole region on the Great Plains support up to three-quarters of North America’s breeding ducks.
The hunting and conservation group Ducks Unlimited works to conserve prairie pothole wetlands on North America’s Great Plains.
Along with providing important habitat for everything from microbes to frogs to waterfowl, wetlands also work to improve water quality. They can capture surface runoff from cities and farmlands and work as natural water filters, trapping excess nutrients that otherwise might create dead zones in lakes and bays. Wetlands can also help remove other pollutants and trap suspended sediments that cloud water bodies, which can kill aquatic plants and animals.
Because wetlands are often in low-lying areas of the landscape, they can store and slowly release surface water. Wetlands can be extremely important for reducing the impacts of flooding. In some places, water entering wetlands can also recharge groundwater aquifers that are important for irrigation and drinking water.
Wetlands also act as important carbon sinks. As wetland plants grow, they remove carbon dioxide from the atmosphere. They they die, sink to the bottom of the wetland and decompose very slowly.
Over time, the carbon they contain accumulates in wetland soils, where it can be stored for hundreds of years. Conserving and restoring wetlands is an important strategy for regulating greenhouse gases and mitigating the impacts of climate change.
Resources at risk
Despite the many valuable services they provide, wetlands are constantly being destroyed by draining them or filling them in, mainly for farming and development. Since 1970, the planet has lost 35% of its wetlands, a rate three times faster than the loss of forests.
Destruction and degradation of wetlands has led to the loss of many organisms that rely on wetland habitat, including birds, amphibians, fish, mammals and many insects. As one example, many dragonfly and damselfly species are declining worldwide as the freshwater wetlands where they breed are drained and filled in. A marsh or bog may not look like a productive place, but wetlands teem with life and are critically important parts of our environment.
