There are more than 8 million species of living things on Earth, but none of them — from 100-foot blue whales to microscopic bacteria — has an advantage over the others in the universal struggle for existence.

In a paper published Jan. 8 in the journal Nature Ecology & Evolution, a trio of scientists from universities in the United States and the United Kingdom describe the dynamic that began with the origin of life on Earth 4 billion years ago. They report that regardless of vastly different body size, location and life history, most plant, animal and microbial species are equally “fit” in the struggle for existence. This is because each transmits approximately the same amount of energy over its lifetime to produce the next generation of its species. Continue reading “What species is most fit for life?

PENANG, Malaysia, Jan 2 2018 (IPS) – Another new year has dawned, and on a world facing serious disruption on many fronts.  What are the trends and issues to watch out for in 2018?

One obvious answer is to anticipate how Donald Trump, the most unorthodox of American Presidents, will continue to upset the world order.  But more about that later.

Just as importantly as politics, we are now in the midst of several social and environmental trends that have important long-lasting effects.  Some are on the verge of reaching a tipping point, where a long-term trend produces critical and sometimes irreversible events. We may see some of that in 2018.

Top 10 HAPPY environmental stories of 2017

Mongabay.com

  • Throughout 2017, scientists discovered new populations of rare wildlife, and rediscovered some species that were previously thought to be extinct.
  • Some countries created large marine protected areas, while a few others granted land rights to indigenous communities.
  • In 2017, we also saw the ever-increasing potential of technology to improve conservation monitoring and efforts.

The past year may have seemed like doom and gloom for the environment, but there was plenty to be thankful for. So once again, we bring you some of the happier environmental stories of 2017 (in no particular order). These include rediscoveries of species that were once thought to be extinct, local communities being granted land rights, and the emergence of new technologies that are boosting conservation efforts.

1. New populations of rare wildlife were found

This year, conservationists discovered some new populations of threatened wildlife. Take, for example, the helmeted hornbill (Rhinoplax vigil). A research team recorded a new and “unexpectedly rich population” of this critically endangered bird in western Borneo. For a species that is now nearly extinct because of poaching, this discovery boosts hope for its future.

It was good news for the Grauer’s gorilla (Gorilla beringei graueri) as well. Surveys in the Democratic Republic of Congo’s Maiko National Park revealed several previously uncounted individuals of Grauer’s gorillas in just 1 percent of the park. The researchers think that there might be many more gorillas living inside the largely unexplored 10,885-square-kilometer (4,000-square-mile) park.

Plankton decline hits marine food chain

DW_Plankton is the basis for the entire marine food web – and it is under threat. From the Mediterranean to the Pacific, animals have been struggling to survive, due apparently to changes with plankton.

Food chains represent the greatest interdependency within the webs of life. The marine food chain, for instance, is essential for oceans – and depends on plankton. But environmental changes and human activities may be threatening plankton– and therefore all marine animals.

According to a recent study,the biomass of sardines and anchovies has been decreasing at alarming rates in the Mediterranean Sea. At the same time, sea lions are struggling to forage on the coasts of California. Both cases have shed light on how a single food chain element can affect all others.

While it is still unknown whether species will be able to adapt to new conditions, the marine food chain is already experiencing drastic changes – and plankton plays a crucial role across the board.

“If anything happens to the plankton, an immediate cascade effect will take place on the food chain,” Ivan Nagelkerken, a University of Adelaide’s biology professor, told DW.

Building blocks of life

Plankton are tiny aquatic organisms that drift through the sea, forming the basis of the marine food chain.

For plankton, both quantity and quality – in terms of nutrients – affect life up the food chain. Continue reading “Plankton decline hits marine food chain”

The world is facing a global sand crisis

September 7, 2017 9.22pm BST

theconversation_When people picture sand spread across idyllic beaches and endless deserts, they understandably think of it as an infinite resource. But as we discuss in a just-published perspective in the journal Science, over-exploitation of global supplies of sand is damaging the environment, endangering communities, causing shortages and promoting violent conflict.

Skyrocketing demand, combined with unfettered mining to meet it, is creating the perfect recipe for shortages. Plentiful evidence strongly suggests that sand is becoming increasingly scarce in many regions. For example, in Vietnam domestic demand for sand exceeds the country’s total reserves. If this mismatch continues, the country may run out of construction sand by 2020, according to recent statements from the country’s Ministry of Construction.

Beijing is building hydroelectric dams and dredging to allow bigger boats as worries of environmental devastation grow.
  • CATEGORIES: DISPATCH

BANGKOK — Thirty million people depend for a living on the Mekong, the great Asian river that runs through Southeast Asia from its origins in the snowfields of Tibet to its end in the delta region of Vietnam, where it fertilizes one of the world’s richest agricultural areas. It’s the greatest freshwater fishery on the planet, second only to the Amazon in its riparian biodiversity. If you control its waters, then you control much of the economy of Southeast Asia.

HANOI (Reuters) – Vietnamese authorities on Monday used water cannon and electric rods to end a five-month long protest by villagers blockading a textile plant that serves global fashion brands, an official and a villager said.

The blockade represents another challenge to the communist nation’s government over industrial pollution woes, at a time when Vietnam seeks more foreign investors to keep up one of the highest rates of growth in Southeast Asia.

Hundreds of people from the northern province of Hai Duong have maintained watch in shifts day and night since April to stop work at the Pacific Crystal Textiles mill, operated by Hong Kong-based Pacific Textiles.

House Construction with Plastic Bottles by Samarpan Foundation

http://www.samarpanfoundation.org — May 2011
Do you remember the last time you bought a drink in a plastic bottle? Chances are that you threw away the bottle, without a second thought, when you were done. That’s what most of us do. Plastic is one of the most disposable materials in the modern world. It makes up much of the street side litter in urban and rural areas. It is rapidly filling up landfills as well as choking water bodies. Plastic bottles make up approximately 11% of the content of landfills, causing serious environmental consequences.

For many days now, people living in My An and My Tho communes of Phu My District have been preventing Hoang Dat Co from exploiting the titanium in the region fearing water pollution.

Dang Ngoc Thai, head of Xuan Phuong village of My An Commune, said previously, a vast casuarina forest covered the region.

“However, since 2006, when the company was allowed to exploit titanium in the region, they have chopped down hectares of the forest. The trucks carrying titanium ores are a constant source of pollution,” he said.

Thai also added that the wells in the village had run dry, forcing residents to spend a hefty sum of money to dig new wells.

In the neighbouring village of Xuan Binh (My An Communme), the foul smell and muddy water are also suspected to be caused by the company’s mining activities.

“Now, if the authorities once again let them resume their mining, then we will suffer further; the environment is heavily polluted already. We demanded a halt on all the titanium mining activities here,” a resident said, expressing his anger. Continue reading “Locals protest against titanium mining in Binh Dinh”

Climate change is disrupting the birds and the bees

BBC_Our changing climate seems set to disrupt just about everything. From rising sea levels to ocean acidification, the list of negative consequences from climate change is endless. But one area that often goes unmentioned in the climate change discussion is sex.

Over the last two decades, scientists have found that warmer temperatures are quietly spoiling the mood, making it harder for plants and animals to reproduce.

Here are five ways that climate change is ruining sex lives.

It’s a numbers game

While humans and many other animals determine sex genetically, many reptiles and some fish use the incubation temperature of the eggs to set the gender of their offspring. This means that changing global temperatures could alter the ratio of sexes produced, making it harder for these animals to find mates.

Asian consumer firms need to buck up on sustainability: New report

eco-business_A new report by WWF has found that most major Asian consumer goods firms are lagging behind their western counterparts on making their operations and supply chains more sustainable, and their investors are also not paying enough attention to environmental risks.

Non-profit group World Wide Fund for Nature (WWF) has published a report shining an uncomfortable spotlight on Asian consumer firms, which finds them severely lagging behind international standards on sustainability.The international group said the lack of sustainability among Asian manufacturers of food, household, and personal care products is in part due to a lack of scrutiny from financiers.
