Sustainable land use
Concepts in sustainable land use include compactness, redeveloping existing infrastructure, green spaces, and housing affordability. Eliminating unnecessary space consumption in the name of luxury and mixed-use development helps save space. Hydroponics enables space-saving urban farming, while permaculture allows agriculture to co-exist with wildlife.
Rather than buying up virgin land, developers should consider redeveloping brownfields and gray fields. Preserving historic sites, biodiverse green spaces, and recreational open spaces should remain critical.
Filling up every open space with buildings and factories is not sustainable. An open space can be used as a park or some other recreational purpose that promotes the well-being of residents.
Urban growth boundary is a technique used to control urban encroachment. It involves designating certain areas of a state for urban expansion and mandating that developments are contained within them.
Why is fish consumption not sustainable
After meat, fish is our primary source of proteins. However, is fish sustainable food? Sustainable seafood refers to seafood caught in the wild or farmed without causing a decline in marine life species. Fishes are abundant in the ocean, but the growing demand reduces their population.
The United Nations Food and Agricultural Organization estimates we overfish 85% of marine fish stocks. We move fish from their habitats before they can reproduce, reducing their population in the ecosystem. Other factors also make it difficult for fish to survive overfishing.
Things like rising sea temperatures, ocean acidification, plastic, and chemical pollution affect fish populations, making it difficult for them to survive overfishing. Overfishing disrupts the marine food web, as fish are a source of nutrients for other marine animals.
These animals would enter a state of decline because they don't feed properly. Also, the method used to fish can cause environmental damage. For instance, bottom trawling is a fishing technique that involves dragging a big net across the seabed. This method catches everything in its path.
It puts endangered animal species, i.e., sea turtles, at risk. Furthermore, the net disturbs the seabed- releasing carbon stored in the sediments. It also reduces the capacity of these areas to absorb carbon in the future.
