There Were 1 Billion Monarch Butterflies. Now There Are 93 Million.

There Were 1 Billion Monarch Butterflies. Now There Are 93 Million. Without pollinators, there is no agriculture—and without that, there is no food.

The CPPC is serious business. Between the destruction of monarch habitats through pesticides, most notably milkweed, and the ongoing mystery of colony collapse among the bees, American agriculture is endangered. At Tuesday night’s event, it was made plain that without agriculture, there is no food, and with pollinators, there is no agriculture.

In 2017, according to the Center For Biological Diversity, the overwintering population of monarchs dropped by a third. The butterfly’s dramatic decline has been driven in large part by the widespread planting of genetically engineered crops. The vast majority of U.S. corn and soybeans are genetically engineered for resistance to Monsanto’s Roundup herbicide, a potent killer of milkweed, the monarch caterpillar’s only food.

The dramatic surge in the use of Roundup and other herbicides with the same active ingredient (glyphosate) on Roundup Ready crops has virtually wiped out milkweed plants in the Midwest’s corn and soybean fields. In the past 20 years, scientists estimate, these once-common, iconic orange-and-black butterflies may have lost more than 165 million acres of habitat — an area about the size of Texas — including nearly a third of their summer breeding grounds. Logging on the monarch’s Mexican wintering grounds is also an ongoing concern.

Scientists have also identified threats to the monarch during the fall migration including lack of nectaring habitat and insecticides.

India Pushes Back Against Tech ‘Colonization’ by Internet Giants

With Facebook, Google and Amazon dominating India’s internet, lawmakers have declared their intention to impose tough new rules on the tech industry. India is trying to establish strong data protections for its citizens, as Europe did, while giving the government the right to obtain private information as it sees fit. For some Indian political leaders, it is as if their nation — which was ruled by Britain for a century until 1947 — is being conquered by colonial powers all over again.

eBay Moves Away From OpenStack, Embraces Kubernetes and Docker

As part of an initiative to completely revamp its data center infrastructure, eBay is “re-platforming, using Kubernetes and Docker and moving away from OpenStack,” according to a message to SDxCentral from Mazen Rawashdeh, VP of platform engineering at eBay. In May 2017 at the OpenStack Summit in Boston, an eBay executive said that 95 percent of all eBay traffic ran on its OpenStack cloud, which at the time managed 167,000virtual machines(VMs) and 4,000 applications. But since then, eBay has pivoted away from OpenStack as part of a major three-year infrastructure initiative.

Feeling the Heat of High-Frequency Trading

It’s high summer here in North America, and for a lot of us, this one has been a scorcher. Media reports have been filled with coverage of heat wave after heat wave, with temperature records falling like dominoes. But as they say, it’s not the heat, it’s the humidity, and that was painfully true in the first week of July as a slug of tropical air settled into the northeast United States.
