Swallowed fishing gear and plastic most likely cause of Hawaii whale’s death

Large volumes of traps, nets and marine debris in sperm whale’s intestinal tract highlight plastic pollution’s threat to wildlife

A sperm whale that washed ashore in Hawaii over the weekend probably died in part because it ate large volumes of fishing traps, fishing nets, plastic bags and other marine debris, scientists said on Thursday, highlighting the threat to wildlife from the millions of tons of plastic that ends up in oceans every year.

The body of the 56ft (17-meter) long, 120,000-pound (54,000kg) animal was first noticed on a reef off Kauai on Friday. High tide brought it ashore on Saturday.

M&S joins calls for EU to restrict harmful tuna fishing methods in Indian Ocean

Retailer and green groups warn of ‘high environmental cost’ of fish aggregating devices to tuna stocks and other endangered marine life

The EU is under pressure to significantly restrict its huge fleet of fishing vessels from using “fish aggregating devices” that make it easier to catch huge numbers of fish and contribute further to overfishing.

A letter signed by Marks & Spencer and more than 100 environmental groups, including the International Pole and Line Foundation, warns EU officials that the devices (FADs) are one of the main contributors to overfishing of yellowfin tuna in the Indian Ocean, because they catch high numbers of juveniles.

Somerset estate offers rare peek into life of beavers with launch of online tour

National Trust project shows family home of ‘nature’s engineers’ and how they have improved the environment for other wildlife

Farmers will be key to plan to restore England’s green spaces and wildlife

Environmental improvement plan includes many ambitious pledges but hard-pressed agricultural sector will need effective support

It has taken years of campaigns and mass trespasses for the government to put access to green space in England at the top of its agenda, as it has today in the environmental improvement plan.

During the pandemic, the importance of nature for our physical and mental wellbeing became ever more apparent – as did the inequality in access, with the poorest in society less able to access green space.

Every household in England ‘to be within 15 minutes of green space or water’

Major environmental plan includes tackling sewage spills and restoring wildlife habitats but critics question lack of funding

Every household will be within a 15-minute walk of a green space or water, under a major environmental improvement plan for England set out by the government on Tuesday.

Human activity and drought ‘degrading more than a third of Amazon rainforest’

Fires, land conversion, logging and water shortages have weakened resilience of 2.5m sq km of forest, says study

Human activity and drought may have degraded more than a third of the Amazon rainforest, double the previous estimate, according to a study that heightens concerns that the globally important ecosystem is slipping towards a point of no return.

Fires, land conversion, logging and water shortages, have weakened the resilience of up to 2.5m sq km of the forest, an area 10 times the size of the UK. This area is now drier, more flammable and more vulnerable than before, prompting the authors to warn of “megafires” in the future.

Food, feed and fuel: global seaweed industry could reduce land needed for farming by 110m hectares, study finds

Scientists identify parts of ocean suitable for seaweed cultivation and suggest it could constitute 10% of human diet to reduce impact of agriculture

An area of ocean almost the size of Australia could support commercial seaweed farming around the world, providing food for humans, feed supplements for cattle, and alternative fuels, according to new research.

Seaweed farming is a nascent industry globally but the research says if it could grow to constitute 10% of human diets by 2050 it could reduce the amount of land needed for food by 110m hectares (272m acres) – an area twice the size of France.

Unusual sightings of the Asian koel in Melbourne raise mysteries for migration researchers

Increase in reports of the koel and its loud mating call south of its usual territory may be attributable to climate change, scientists say

Climate change may be one reason why the so-called devil bird – known for its incessant late-night mating call – has become more common in Melbourne’s outer suburbs, according to researchers.

The koel, a migratory bird, usually arrives in Australia from Papua New Guinea and Indonesia to breed from late September to early October, when the male will sing his advertising call day and night to attract a female.

Encouraging sign for river that suffered as dumping ground for waste from nearby factories
