If the plastics industry is following the tobacco industryโs playbook, it may never admit to the failure of plastics recycling. Although we may not be able to stop them from trying to fool us, we can pass effective laws to make real progress. Single-use-plastic bans reduce waste, save taxpayer money spent on disposal and cleanup, and reduce plastic pollution in the environment.
Consumers can put pressure on companies to stop filling store shelves with single-use plastics by not buying them and instead choosing reusables and products in better packaging. And we should all keep recycling our paper, boxes, cans, and glass, because that actually works.

Deep-sea ecosystems are so vastly understudied, itโs unclear how human noise pollution might affect Challenger Deepโs inhabitants. But based on the effect it has had on other marine species, the impact is likely to be negative. That said, thanks to the data collected during this project, oceanographers now have a record of sounds that can double as a baseline for the health of this ecosystem. As future studies continue to eavesdrop on Challenger Deep, they can use this data to assess how the soundscape has changed over time, and more importantly, if this noise pollution problem is getting worse.
Rewilding has huge momentum right now. The idea, as most artfully expressed by entomologist Doug Tallamy, is that even in suburban and urban areas, we can make a huge difference in helping the environment by planting native plants and trees. โNativeโ refers to โpre-settlerโ and acknowledges the legacy of Indigenous land management for the good of the environment and human beings. Native plants have evolved over thousands of years to be the best hosts for the largest number of birds, butterflies, bees, and other organisms. Audubon suggests that yards be comprised of at least 70 percent native plants, bushes, and trees, or, for example, chickadees canโt find enough caterpillar food for their young.
- Become familiar with the wildflowers native to your area.
- Decide the scope of your ambition.
- Buy your wildflowers or seeds from the right sources.
- Be extra aware of how close planting can affect native plants.
- Avoid actively harmful plants.
- Mix in some useful non-native flowers to round out your selection.
- Consider scale and the effect of pruning on plant health.
- Think about the caterpillars.
This had me going to my local council and looking for resources. Also, the mention of the raccoon reminded me of the grapples faced with possems.
Possum Eating My Plants Update: the cat has finally started to be a proper guard-pet and alerts me to the intruder on our balcony. I go out and give the ringtail stern lectures every night.
Itโs not working. During todayโs telling-off, the possum came up and sniffed my phone. pic.twitter.com/YMRP1F88zu

Natural rubber is a uniquely tough, flexible and highly waterproof material. It puts tyres on our vehicles, soles on our shoes, it makes seals for engines and refrigerators, insulates wires and other electrical components. It is used in condoms and clothing, sports balls and the humble elastic bands. Over the past year it has played a pivotal role in the pandemic in personal protective equipment worn by doctors and nurses around the world.
In fact, rubber is deemed to be a commodity of such global importance that it is included on the EU’s list of critical raw materials.
Unfortunately, there are signs the world might be running out of natural rubber. Disease, climate change and plunging global prices have put the world’s rubber supplies into jeopardy. It has led scientists to search for a solution before it’s too late.
“We have enough dandelion seed to put in 40 hectares (0.15 sq miles) of vertical farm, and 3,000 hectares (11.6 sq miles) of guayule, but we need the funds to do it,” says Cornish. “We need some of those billionaires to get involved. I am determined to get this established before I die. We’ve got to get it to work. The consequences to the developed world if the crop fails are unthinkable.”
What are the practices which will leave the world better than it is now? What are the aspects of our environment that we wish to encourage, compared to those we want to avoid? How can we ensure that the things we like become the norm by the time our grandchildren arrive?
Don’t get firewood from the fruit-bearing trees. Strip the bark from the poisonous ones.
Mann suggests, the Europeans were wrong. They had quite literally failed to see the forest for the trees. The environment laden with fruit, vegetables and calories wasn’t something that happened to people: it was the result of people. The lush, dense rainforest, so alien to Europeans hacking through it with machetes, was not actually a tabula rasa, any more than the American northwest. It was, instead, the result of an independent invention of agriculture โ and an agriculture quite unlike any other in the world.
Interesting to consider alongside Beau Miles’ work and his appeal to radical change.
Human civilization has a waste problem, and itโs likely to get worse as population levels grow and a consumerist mentality becomes the global norm. But there are many clever, practical ways to deal with waste, including bioremediation – a nature-inspired approach.
I also enjoyed RN Future Tense’s exploration of the role played by trees in the fight against global warming.
When it comes to the transitions towards zero carbon, heating is a promising target. Cutting edge technology could make the ingoing energy more renewable and less wasteful. And more broadly, these designs are about tailoring heating systems to the environment around them, from pulling ambient heat from the sewers below, to taking note of the precise angle of the sun in the winter sky.
Rather than pitting our heating systems against the environment, they can be redesigned to make the most of it.
The idea of giving personhood to nature has been slowly gaining adherents. Environmentalists have prodded governments and courts to award rights to lakes, hills, rivers, and even individual species of plants. The New Zealand parliament has given legal rights to the Whanganui River, while Colombia has made the Pรกramo de Pisba region in the Andesโthreatened for years by miningโa โsubject of rights.โ About three dozen towns across the US are passing Toledo-style bills, and the Florida Democratic Party lists the rights of nature in its party platform.
The climate crisis is fully main stage, with California burning and Florida drowning. If we’re going to forestall worse to come, we need innovation not just in techโmore clean energy, resilient cities, genetically modified crops that need less fertilizerโbut in law, the rule sets that architect our behavior.
Plenty of clever techniques to demolish exist. Some start at the base and work up, others in reverse.
The 40-storey Akasaka Prince Hotel in Tokyo was slowly demolished in 2012-13 using a technique where a cap was built on top of the building.
It was stripped floor by floor as the cap was lowered, so all the dust, mess and debris was contained and removed with no effect on the environment.
Buildings are wrapped in scaffold and protective fabric then literally dismantled in the reverse order to which they were built. In the process building waste can be recycled and reused rather than dumped.
Reverse building involves removing the glass, then the frames, taking off the wall cladding, then scraping away at the concrete and steel frames bit by bit.
Concrete is removed to expose the steel reinforcing bars, which are then separately removed and recycled. In the process unwanted material can be uncovered, like asbestos, which needs particular care in handling.
The CSIRO (2016) outlined balloons as being in the top three most harmful pollutants threatening marine wildlife. Every day, balloons are released or accidentally escape from outdoor events where they almost definitely end up in waterways and oceans and can be mistaken by animals for food.
Awareness of the damage caused by our addiction to sand is growing. A number of scientists are working on ways to replace sand in concrete with other materials, including fly ash, the material left over by coal-fired power stations;ย shredded plastic; and even crushed oil palm shells andย rice husks. Others are developingย concrete that requires less sand, while researchers are alsoย looking at more effective ways to grind down and recycle concrete.
Vertical farming is a bit of a buzz term. Despite the hype, itโs an important part of a growing approach to food production known as Controlled Environmental Agriculture.
Controlled Environmental Agriculture promises to be cleaner and greener. Itโs focussed on technology and itโs essentially about bringing food production closer to the point of consumption.
We examine the potential and the pitfalls.

You sort your recycling, leave it to be collected โ and then what? From councils burning the lot to foreign landfill sites overflowing with British rubbish, Oliver Franklin-Wallis reports on a global waste crisis
Thinking about climate change is degraded by climate change itself, just as communications networks are undermined by the softening ground, just as our ability to debate and act on entangled environmental and technological change is diminished by our inability to conceptualise complex systems. And yet at the heart of our current crisis is the hyperobject of the network: the internet and the modes of life and ways of thinking it weaves together (Page 79)
The other problem is where the data gets manipulated to support vested interests.
