Why Millions of Monarch Butterflies Are Dying in Mexico
By Alicia Graef
While international efforts are underway to help keep dwindling populations of monarch butterflies from disappearing, scientists are raising concerns about how severe weather and a loss of forest habitat at their wintering grounds in Mexico are affecting them.
Every year, monarchs embark on an epic multigenerational migration that takes them thousands of miles from Canada and the U.S. in search of sites in California and Mexico. The fir trees in the southern regions offer the shelter and warmth they need to survive the winter.
Unfortunately, these vital forests in Mexico have been threatened by illegal logging and now storms have destroyed hundreds of acres of habitat, while severe weather is believed to have killed an estimated 6.2 million of these iconic butterflies.
"Since the forests provide the microclimate needed for butterflies to survive the winter, illegal logging must be eradicated and degraded areas need to be restored," Omar Vidal, CEO of World Wildlife Fund (WWF) Mexico, said. "This would help the monarch butterfly to better adapt to extreme climate events and also provide local communities with sustainable economic alternatives."
These fragile butterflies already face high mortality rates along their route from other threats that range from predators and parasites to a loss of habitat along their migration path. They travel north in the spring in search of milkweed plants—the only plant that monarchs lay eggs on and caterpillars eat. But these plants are being destroyed by the herbicide glyphosate, which is sprayed on fields where genetically modified Roundup-ready corn and soy crops are grown.
According to the Xerces Society, in the 1990s, an estimated one billion monarchs made this migration, but over the past 15 years, they've lost millions of acres of habitat and the number of monarchs has steadily dropped by 80 percent or more by some estimates.
The good news is that these butterflies are not without advocates working to help them recover. Individuals are working in their gardens and communities to improve butterfly habitat. Conservation organizations are working on other measures, including seeking endangered species status for monarchs and working on habitat restoration.
The National Fish and Wildlife Foundation recently announced more than $3 million in grants from its Monarch Butterfly Conservation Fund, which were matched for a total of $9 million, will be used to restore approximately 16,000 acres of key habitat to support monarchs' survival.

No matter the time of year, there's always a point in each season when my skin decides to cause me issues. While these skin issues can vary, I find the most common issues to be dryness, acne and redness.

Now, correspondence obtained by the LA Times revealed just how deeply involved industry lobbyists and a controversial, industry-funded toxicologist were in drafting the federal agency's proposal to scrap its current, protective approach to regulating toxin exposure.
February 22 is the birthday of conservationist and beloved TV personality "Crocodile Hunter" Steve Irwin, who would have been 57 years old today.
Irwin's life was tragically cut short when the barb from a stingray went through his chest while he was filming in 2006, but his legacy of loving and protecting wildlife lives on, most recently in a Google Doodle today honoring his birthday.

That video showed the extrusion of a bubblegum-pink substance oozing into a coiled pile, something between Play-Doh, sausage and soft-serve strawberry ice cream. Branded "pink slime"—the name came from an email sent by a USDA microbiologist in 2002—this stuff was actually beef, destined for supermarkets and fast-food burgers.
'Kicking Ass for Her Generation': Applause for 16-Year-Old Greta Thunberg as EU Chief Pledges Billions to Curb Climate Threat

Sixteen-year-old climate action leader Greta Thunberg stood alongside European Commission President Jean-Claude Juncker Thursday in Brussels as he indicated—after weeks of climate strikes around the world inspired by the Swedish teenager—that the European Union has heard the demands of young people and pledged a quarter of $1 trillion budget over the next seven years to address the crisis of a rapidly heating planet.
In the financial period beginning in 2021, Juncker said, the EU will devote a quarter of its budget to solving the crisis.
