Renewed Hope for Eastern Monarch Butterfly?
The yearly count of monarch butterflies overwintering in Mexico, released Wednesday, shows an increase of 144 percent from last year's count and is the highest count since 2006. That's good news for a species whose numbers had fallen in recent years, but conservationists say the monarch continues to need Endangered Species Act protection.
The count of 6.05 hectares of occupied forest is up from 2.48 hectares last winter. The increase is attributable to favorable weather during the spring and summer breeding seasons and during the fall migration. Monarchs have lost an estimated 165 million acres of breeding habitat in the U.S. to herbicide spraying and development.
"This reprieve from bad news on monarchs is a thank-you from the butterflies to all the people who planted native milkweeds and switched to organic corn and soy products," said Tierra Curry, a senior scientist at the Center for Biological Diversity. "But one good weather year won't save the monarch in the long run, and more protections are needed for this migratory wonder and its summer and winter habitats."
In 2014 conservationists led by the Center for Biological Diversity and the Center for Food Safety petitioned the U.S. Fish and Wildlife Service to protect the butterfly under the Endangered Species Act. The Fish and Wildlife Service's initial decision was that endangered species protection may be warranted, and a final decision will be issued by June.
"The question is whether the Trump administration wants to do Monsanto's bidding or protect monarchs for future generations," said George Kimbrell, legal director at the Center for Food Safety. "This year's count is a temporary reprieve that doesn't change what the law and science demands, which is that we protect monarchs under the Endangered Species Act before it's too late."
As recently as the mid-1990s, monarchs covered nearly 21 hectares of forest in their wintering ground, falling to less than 1 hectare in 2014. Scientists estimate that 6 hectares is the threshold to be out of the immediate danger zone of migratory collapse.
About 99 percent of all North American monarchs migrate each winter to oyamel fir forests on 12 mountaintops in central Mexico. Scientists from World Wildlife Fund Mexico estimate the population size by measuring the area of trees turned orange by the clustering butterflies.
Monarch butterflies west of the Rocky Mountains overwinter on the coast of California. Their numbers dropped to fewer than 30,000 this year, down from 1.2 million two decades ago.
A recent study found that if current trends continue, the western population has a 63 percent chance of extinction in 20 years and more than an 80 percent chance of extinction within 50 years. The western population is now at the threshold of extinction.
The caterpillars only eat milkweed, but the plant has been devastated by increased herbicide spraying in conjunction with corn and soybean crops that have been genetically engineered to tolerate direct spraying with herbicides. In addition to glyphosate, monarchs are threatened by other herbicides and by neonicotinoid insecticides that are toxic to young caterpillars.
Climate change also threatens to disrupt the monarch's migration and render its overwintering habitats unsuitable by the end of the century.

It is far too easy to view scarcity and poor quality of water as issues solely affecting emerging economies. While the images of women and children fetching water in Africa and a lack of access to water in India are deeply disturbing, this is not the complete picture.
The Past is No Longer a Guide to the Future
We get ever closer to "day zeros" — the point at when municipal water supplies are switched off — and tragedies such as Flint. These are not isolated stories. Instead they are becoming routine, and the public sector and civil society are scrambling to address them. We are seeing "day zeros" in South Africa, India, Australia and elsewhere, and we are now detecting lead contamination in drinking water in cities across the U.S.
"Day zero" is the result of water planning by looking in the rear-view mirror. The past is no longer a guide to the future; water demand has outstripped supplies because we are tied to business-as-usual planning practices and water prices, and this goes hand-in-hand with the inability of the public sector to factor the impacts of climate change into long-term water planning. Lead in drinking water is the result of lead pipe service lines that have not been replaced and in many cases only recently identified by utilities, governments and customers. An estimated 22 million people in the US are potentially using lead water service lines. This aging infrastructure won't repair or replace itself.
One of the most troubling aspects of the global water crisis is that those least able to afford access to water are also the ones who pay a disproportionately high percentage of their income for it. A report by WaterAid revealed that a standard water bill in developed countries is as little as 0.1 percent of the income of someone earning the minimum wage, while in a country like Madagascar a person reliant on a tanker truck for their water supply would spend as much as 45 percent of their daily income on water to get just the recommended daily minimum supply. In Mozambique, families relying on black-market vendors will spend up to 100 times as much on water as those reached by government-subsidized water supplies.
Finally, we need to understand that the discussion of a projected gap between supply and demand is misleading. There is no gap, only poor choices around allocation. The wealthy will have access to water, and the poor will pay more for water of questionable quality. From Flint residents using bottled water and paying high water utility rates, to the poor in South Africa waiting in line for their allocation of water — inequity is everywhere.
Water Inequity Requires Global Action — Now.
These troubling scenarios beg the obvious question: What to do? We do know that ongoing reports on the 'water crisis' are not going to catalyze action to address water scarcity, poor quality, access and affordability. Ensuring the human right to water feels distant at times.
We need to mobilize an ecosystem of stakeholders to be fully engaged in developing and scaling solutions. The public sector, private sector, NGOs, entrepreneurs, investors, academics and civil society must all be engaged in solving water scarcity and quality problems. Each stakeholder brings unique skills, scale and speed of impact (for example, entrepreneurs are fast but lack scale, while conversely the public sector is slow but has scale).
We also urgently need to change how we talk about water. We consistently talk about droughts happening across the globe — but what we are really dealing with is an overallocation of water due to business-as-usual practices and the impacts of climate change.
We need to democratize access to water data and actionable information. Imagine providing anyone with a smartphone the ability to know, on a real-time basis, the quality of their drinking water and actions to secure safe water. Putting this information in the hands of civil society instead or solely relying on centralized regulatory agencies and utilities will change public policies.

- Mice exposed to nicotine-containing e-cigarette vapor developed lung cancer within a year.
- More research is needed to know what this means for people who vape.
- Other research has shown that vaping can cause damage to lung tissue.
A new study found that long-term exposure to nicotine-containing e-cigarette vapor increases the risk of cancer in mice.
Six months: That's how much time Mexico now has to report on its progress to save the critically endangered vaquita porpoise (Phocoena sinus) from extinction.
It may seem innocuous to flush a Q-tip down the toilet, but those bits of plastic have been washing up on beaches and pose a threat to the birds, turtles and marine life that call those beaches home. The scourge of plastic "nurdles," as they are called, has pushed Scotland to implement a complete ban on the sale and manufacture of plastic-stemmed cotton swabs, as the BBC reported.

Scientists in the U.S. have added a new dimension to the growing hazard of extreme heat. As global average temperatures rise, so do the frequency, duration and intensity of heatwaves.
Oscar-award winning actress and long-time political activist Jane Fonda was arrested on the steps of Capitol Hill in Washington, DC on Friday for peacefully protesting the U.S. government's inaction in combating the climate crisis, according to the AP.
