Why Shark Attacks Have a Silver Lining
While recent headlines about the above average number of shark attacks in the U.S. this year may have rethinking your summer vacation, the incidents could be good news for the ocean’s ecosystem.
Conservation measures implemented to prevent the decline of great white sharks are paying off, scientists have found. The global population of great whites has been in recovery since 1990.
One of the key components in this environmental success story is the passage of the Marine Mammal Protection Act in 1972. With the legislation, seal and sea lion populations began to rebound along the West Coast. Great white sharks eat both seals and sea lions and having more food available most likely boosted their comeback.
A healthy shark population makes for a more balanced ecosystem, leading to healthier oceans that support all lives, both human and non-human. Oceans produce over half of the oxygen in the atmosphere and absorb the majority of carbon in it.
The increase in the number of sharks suggests that some of the damage humans have caused in the oceans has been reversed. However, it will take a while for sharks to rebuild their populations completely. It takes sharks at least eight years to reach a reproductive age and gestation periods can last 18 months.
Even though “Sharknado: Oh Hell No!” is getting awful reviews this week, everyone should applaud this other bit of shark-related news.
Chart of the Day: Boosting Corporate Tax Revenues
The leading candidates for the Democratic presidential nomination have all proposed increasing taxes on corporations, including raising income tax rates to levels ranging from 25% to 35%, up from the current 21% imposed by the Republican tax cuts in 2017. With Bernie Sanders leading the way at $3.9 trillion, here’s how much revenue the higher proposed corporate taxes, along with additional proposed surtaxes and reduced tax breaks, would generate over a decade, according to calculations by the right-leaning Tax Foundation, highlighted Wednesday by Bloomberg News.
Chart of the Day: Discretionary Spending Droops
The federal government’s total non-defense discretionary spending – which covers everything from education and national parks to veterans’ medical care and low-income housing assistance – equals 3.2% of GDP in 2020, near historic lows going back to 1962, according to an analysis this week from the Center on Budget and Policy Priorities.
Chart of the Week: Trump Adds $4.7 Trillion in Debt
The Committee for a Responsible Federal Budget estimated this week that President Trump has now signed legislation that will add a total of $4.7 trillion to the national debt between 2017 and 2029. Tax cuts and spending increases account for similar portions of the projected increase, though if the individual tax cuts in the 2017 Republican overhaul are extended beyond their current expiration date at the end of 2025, they would add another $1 trillion in debt through 2029.
Chart of the Day: The Long Decline in Interest Rates
Are interest rates destined to move higher, increasing the cost of private and public debt? While many experts believe that higher rates are all but inevitable, historian Paul Schmelzing argues that today’s low-interest environment is consistent with a long-term trend stretching back 600 years.
The chart “shows a clear historical downtrend, with rates falling about 1% every 60 years to near zero today,” says Bloomberg’s Aaron Brown. “Rates do tend to revert to a mean, but that mean seems to be declining.”
Chart of the Day: Drug Price Plans Compared
Lawmakers are considering three separate bills that are intended to reduce the cost of prescription drugs. Here’s an overview of the proposals, from a series of charts produced by the Kaiser Family Foundation this week. An interesting detail highlighted in another chart: 88% of voters – including 92% of Democrats and 85% of Republicans – want to give the government the power to negotiate prices with drug companies.
