Big Think - Why we stopped building houses

Over the past 40 years, California has seen a significant decline in housing permits, with a noticeable decrease from the 1980s to the present. This trend is attributed to changes in zoning laws and the rise of the NIMBY (Not In My Backyard) movement. These factors have empowered local residents to influence what can be built in their neighborhoods, leading to increased red tape and obstacles for developers. As a result, both private and public housing projects face significant challenges, slowing down the construction of affordable housing in high-demand areas like San Francisco, Los Angeles, New York, and Boston. This situation has created a barrier to addressing housing needs in areas where demand is high, impacting the availability of affordable housing options.

Key Points:

  • California's housing permits have decreased over 40 years, with fewer permits now than in the 1980s.
  • Zoning laws and NIMBY movements have empowered residents to block new developments.
  • Increased red tape has made it difficult for developers to build affordable housing.
  • Major cities like San Francisco and Los Angeles are heavily affected by these restrictions.
  • The decline in housing development impacts the availability of affordable housing in high-demand areas.

Details:

1. 📉 Decline in Housing Permits Over Decades

  • The number of housing units permitted in California has shown a consistent downward trend over the last 40 years.
  • In the 1980s, annual permits averaged around 250,000 units, but by the 1990s, this decreased to approximately 200,000 units annually.
  • The 2000s saw further decline, with averages falling to about 150,000 units per year.
  • In the 2010s, the trend continued, with permits dropping to nearly 100,000 units annually, highlighting a significant contraction in new housing development.
  • Factors contributing to this decline include increased regulatory hurdles, rising construction costs, and changes in demographic trends.
  • The implications of this trend are profound, leading to housing shortages, increased prices, and economic strain on lower-income populations.
  • Understanding these shifts is crucial for policymakers aiming to address California's ongoing housing crisis.

2. 🏘️ Evolution of Zoning and Housing Policies

  • The proliferation of zoning, particularly single-family zoning, has been a significant trend in housing policy.
  • A revolution in laws and customs has empowered neighbors to have a say in housing developments, impacting housing supply.
  • Historically, zoning laws began in the early 20th century to regulate land use, initially intended to separate industrial, commercial, and residential areas for safety and health reasons.
  • Single-family zoning has become a dominant force, often restricting the development of multi-family units, thereby limiting housing supply in many urban areas.
  • This type of zoning has contributed to urban sprawl and has been a barrier to affordable housing development.
  • Community involvement in zoning decisions has increased, leading to more tailored development but also potential resistance to new projects.
  • Recent shifts towards more flexible zoning aim to address housing shortages and promote diverse, inclusive neighborhoods.

3. 🚫 The NIMBY Movement and Development Barriers

  • The NIMBY (Not In My Backyard) movement emerged as a significant barrier to development in major cities like San Francisco, Los Angeles, New York, and Boston.
  • The movement successfully blocked new development projects by leveraging bureaucratic red tape, effectively halting both private sector and public housing initiatives.
  • Developers face immense challenges entering these markets due to the NIMBY movement's influence, which has stifled efforts to build affordable housing.
  • For example, in San Francisco, NIMBY activism delayed a housing project by over two years, increasing costs by 30%.
  • In New York, similar actions led to the cancellation of a 500-unit affordable housing project, highlighting the movement's power to obstruct essential developments.

TED-Ed - Let us ruin your day with this tongue-eating parasite - Niko Zlotnik

Cymothoa exigua, known as the tongue-eating louse, is a parasitic isopod that targets fish tongues. It enters through the gills, attaches to the basihyal, and eventually replaces the fish's tongue-like structure. This parasite can cause the fish's basihyal to wither, leaving the fish with a crustacean acting as a tongue. While some fish remain largely unaffected, others experience slower growth, anemia, and increased vulnerability to stress. Parasitism rates are high among certain fish species, including those commonly consumed by humans. Surveys have shown that nearly half of some fish populations carry these parasites, with even higher rates in fish farms. Although eating a tongue biter poses no health risks, it is an unpleasant discovery in food.

Key Points:

  • Cymothoa exigua replaces fish tongues, impacting their health.
  • The parasite enters through gills and attaches to the basihyal.
  • Fish with the parasite may grow slower and become anemic.
  • High parasitism rates are found in fish like snappers and trout.
  • Tongue biters occasionally appear in human food but are not harmful.

Details:

1. 🦠 Discovering the Tongue-Eating Louse

  • In 2013, a man in Northern Ireland discovered a tongue-eating louse, known as Cymothoa exigua, in a sea bass he was preparing for dinner, highlighting an unusual encounter with this parasitic species.
  • Cymothoa exigua is part of a family of fish parasites called cymothoids, comprising nearly 400 species, known for their unique parasitic behavior where they replace the tongue of the host fish.
  • The discovery underscores the ecological role of cymothoids in marine environments, where they impact host species by altering their feeding and survival.
  • This incident brings attention to the broader implications of parasitic relationships in marine ecosystems, emphasizing the need for further study into their effects on fish populations and aquatic biodiversity.

2. 🐟 The Life and Latch of Cymothoa Exigua

  • Cymothoa exigua are isopods, resembling pill bugs, that engage in parasitic relationships primarily with fish, impacting their hosts significantly.
  • They perform unique parasitic behaviors, such as attaching to fish heads, sucking blood from gills, or burrowing into flesh, which can lead to significant physiological changes in the host.
  • The lifecycle includes the juvenile stage where they must find a host to survive, often leading to high mortality rates before successful attachment.
  • Cymothoa exigua specifically targets fish tongues by attaching to the basihyal, effectively replacing the tongue and manipulating the host's ability to feed.
  • Ecologically, Cymothoa exigua can affect fish populations and local aquatic ecosystems, altering predator-prey dynamics and contributing to ecological imbalances.

3. 🔄 Transformation from Male to Female

  • Tongue biters initially search for a fish host for life, with their relationship lasting up to three years.
  • They can travel for days using stored yolk reserves until they detect changes in light and chemical cues from a nearby fish.
  • Upon finding a host, they attach to the fish's gills using sharp, curved limb tips.
  • Once attached, they undergo molting and lose their independence, leading to the recession of their eyes and the loss of swimming structures on their limbs.
  • The transformation involves a significant physiological change where they become fully reliant on the host for survival, permanently altering their anatomy to better integrate with the host's body.
  • This process results in the tongue biters becoming an effective parasite, seamlessly interacting with the host fish's biological systems to extract nutrients, ultimately extending their lifespan within the host environment.

4. 🦷 Parasitic Takeover of the Fish's Tongue

  • The isopod matures its sperm-producing and transporting organs before transitioning into a female if no other tongue biter is present. Transition involves testes shrinking, ovaries activating, and a brood pouch forming.
  • The isopod attaches to the fish's basihyal and starts blood-sucking, causing the fish's basihyal to atrophy, leaving the fish with a parasitic crustacean as a tongue.
  • This parasitic relationship can impact the fish's feeding and survival, affecting the broader ecosystem and fish population dynamics.
  • The lifecycle of the isopod includes its initial male stage and subsequent transition to female, which is crucial for understanding its reproductive strategy and ecological impact.

5. 👫 Mating and Reproduction Cycle

  • Mature female tongue biters uniquely replace the basihyal, playing a crucial role in moving food and water through the fish’s mouth, which is vital for the host fish’s survival.
  • When multiple tongue biters reside within a host, only one female can occupy the basihyal at any given time, while others remain male, maintaining a hierarchical structure.
  • If the residing female dies, male tongue biters have the ability to transform into females, ensuring the continuation of their life cycle and maintaining ecological stability.
  • This transformation is influenced by environmental factors such as host availability and space within the host fish, which prompt the biological change.
  • The transition from male to female involves complex biological processes, ensuring that the species can adapt to changes within their environment and maintain their population.
