The scoop: Jersey Shore has clean water compared to many parts of the country, but certain beaches still test unsafe for swimming more than 40% of the time.

Key causes of water contamination:

  • outdated sewage systems
  • overdevelopment of beachfronts
  • factory farming spillovers
  • storm runoff

Bottom line: Jersey Shore water was much dirtier 30 or 40 years ago. But some Jersey Shore towns still need serious help improving their water infrastructure. Read below to learn how they can fix that.

Big picture: GM announced plans to release an electric Hummer in 2023. It got me thinking, is it time to make the switch to electric vehicles?

Benefit of electric vehicles:

  1. Lower carbon footprint... social impact ✓
  2. Lower maintenance costs... convenience factor ✓
  3. Tax credits... financial incentive ✓

Cost of electric vehicles:

  1. EVs require minerals like cobalt and lithium to function. Mineral mining is a tough industry with poor standards in developing countries like Bolivia and Chile. Organizations are working to change that.
  2. Electric vehicles have a limited driving range compared to their gas cousins. You may find yourself charging up more than usual.
  3. High sticker prices: The average price of a new electric vehicle is almost double the price of a gas car.
  4. Limited amount of charging stations: this is a tricky one, because there are still more charging stations per EV on the road than there are gas stations for gas cars. Unless you go on a road trip, most of your charging will probably be at home anyway.

Bottom line: With billions of dollars flowing in, electric vehicles are not only here to stay, they are booming.

If you 1) need a car in your life 2) want to be a part of a cleaner future and 3) can afford the extra monthly cost (for now), then making a switch to electric vehicles is the right thing to do.

The scoop: Overpopulation is a myth... because Jack Ma and Elon Musk said so. On a more serious note, a population collapse is more likely than an overpopulated planet.

Some talking points for the dinner table:

  1. Overcrowded cities ≠ overcrowded planet. The entire world population can fit in the state of Texas with the same population density as Manhattan.
  2. Lopsided populations will inevitably occur in modern advanced nations. That means young workers will be unable to support aging populations, causing natural population declines.
  3. 'Malthusian traps' refer to inevitable food shortages as populations grow. Either Malthus was right and some of us go hungry (as in we don't need to artificially halt population growth), or he's wrong and the population keeps growing sustainably through innovation.

Bottom line: The Earth has plenty to offer for 9 billion mouths. And a sustained population decline due to lower fertility rates is already becoming a realistic outcome. We just need to spread out more.

Big picture

  • If all sunlight received by Northern Africa converted into solar energy, it could power all of Europe more than 1000 times over.
  • Concentrated solar power (CSP) technology can use lenses and mirrors to store large amounts of solar heat. 
  • Tunisian transcontinental transmission of photovoltaic power (PV) and CSP prove this concept.
  • PV is more reliable for decentralized plants to power rural regions in Africa.

Between the lines

  • To better understand how a CSP plant works, check out the Ivanpah Solar Electric Generating System in California’s Mojave Desert (link below)
  • Desert solar panels can improve climate conditions in the region.
    • Compared to sand, panels reflect lower amounts of heat to space.
    • The result: surface heating in the desert and cloud formation.
    • Changing the desert’s heat budget may increase rain, but too many panels can raise temperatures to an unproductive level. Panels are less reflective than desert soil. 

Questions to consider

  • Which companies/countries would fund the project? 
  • Who benefits most from affordable solar electricity, Africa or Europe? 
  • How can you export energy to nations inside and outside of Africa?

Why it matters

  • CSP can release energy overnight, creating a 24-hour source of energy.
  • CSP has a high initial set-up cost but has long-term advantages over traditional forms of energy generation such as hydroelectricity.

Bottom line The developing world has a unique opportunity to learn harsh lessons from 20th century economic development principles. Using natural phenomena like the Sahara Desert for solar energy or the Congo River for hydro, Africa can become the energy superpower of the future.

The scoop: Food takeout and delivery accounts for considerable waste. About 29% of all greenhouse emissions come from packaging. And food takeout uses a lot of packaging.

Takeout packaging: You want a burrito? Let me wrap that in foil for you. Here's some plastic utensils and paper napkins wrapped in plastic to go along with your hand-held meal. Ok, now here are three packs of ketchup and hot sauce you didn't ask for because you have condiments at home. Let me put that in a paper bag placed in a plastic bag for you... even though you are about to eat it.

Sustainable solutions: Reduce and reuse. Buy in bulk. Use bulk alternatives when on the go. Shop at restaurants that use sustainable alternatives like plant fibers for their packaging. If you have a good relationship with your local food business, talk to them about affordable options.

The scoop: 40% of insect species are at risk of extinction.

Why it matters: We need bugs to survive and thrive.

  • Pollination: Pollinators pollinate plants; we need them to keep doing that.
  • Pest control: Paradoxically, predatory and parasitic insects kill pests.
  • Decomposition: Some insects are primary or secondary decomposers. They serve an important function to clean-up animal waste.
  • Food security: Many mammals, birds, reptiles and amphibians depend on bugs for food. They are a quick and easy resource for a nutritious meal.
  • Research and innovation: Technology mimics nature (think birds and planes). Researchers can observe the ethology of insects and learn new ways to innovate. An example? Ant colony optimization in computer science.

What's causing the insect decline: Habitat loss from agriculture and urbanization is the #1 driver. Agro-chemical pollutants (think pesticides), invasive species and climate change also play a role. You can check out some cool charts and figures below to learn more.

How to help: Contribute to the fight against pesticides, support or start a small farm, and educate others about the importance of insects. A more positive perception of 'bug people' can also lead to change.

Bottom line: We need bugs to survive, yet insect populations are on the decline. This issue deserves more recognition.
