Today in Miami and other coastal cities, construction cranes populate the skyline, building more and more skyscrapers at the water’s edge. Few believe we live in a climate emergency. Unfortunately, few want to accept this reality. When the waters rise and do not recede, living shorelines (mangroves, mangroves and more mangroves) and yes, eventually, managed retreat, will prove to be the better options. Let’s instead spend our money and efforts on finding climate solutions that are equitable, responsive and forward-thinking.ĭesperate times call for desperate measures and, smack dab in the middle of an existential crisis, these are desperate times.
The wall will only address storm surge, and only on the northwest coast of the bay. Spending all of that money ($4.6 billion) to kill our bay will ultimately still leave us vulnerable to sea-level rise. No matter how tall we build the wall, the water will rise through the oolite limestone beneath our feet. How much is your waterfront condo going to be worth when the water, devoid of oxygen, looks like pea soup and smells like death? How will your business thrive when tourists and their dollars stop visiting you?Īnd to what end will building this wall take us? We’re not saving properties here. We are talking about ecosystem collapse here! The disruption caused by building a concrete wall, coupled with it being polluted by nutrient sources from the watershed, could be the final straw that ushers in a permanent regime change from sea grasses to persistent algae blooms. The collapse of sea grass communities in north Biscayne Bay, which began in 2013, and the large-scale fish mortality events that occurred in the summer of 2020 clearly demonstrate the sensitivity of the ecosystem. This last one is really important right about now, as local politicians are seriously considering whether or not to give our bay the kind of sea grass scarring 100,000 propellers wouldn’t even be able to do.īuilding a 20-foot wall across Biscayne Bay would cause irreparable harm to a body of water already teetering on survival. I will urge my politicians to protect Biscayne Bay. I will conserve water with shorter showers. I will use nontoxic pesticides and household products. I will pick up trash, even if it isn’t mine. Limestone often contains variable amounts of silica in the form of chert.I will use less or no fertilizer on my lawn. These organisms secrete shells made of aragonite or calcite, and leave these shells behind after the organisms die. Other carbonate grains comprising limestones are ooids, peloids, intraclasts, and extraclasts. Most grains in limestone are skeletal fragments of marine organisms such as coral or foraminifera. Like most other sedimentary rocks, limestone forms in shallow, calm, warm marine waters and is composed of grains.
More History: Limestone is a sedimentary rock. It gives relief for muscle spasms, nurtures, grounds and works primarily well on the Root Chakra.įeng Shui: Use this stone in the Center area for health, overall wellness and balance. This is why limestone is such a mult-dimensional stone.įolk Remedies: Limestone is a healing stone beneficial to overall health and well being. Therefore, it takes on the metaphysical properties of its additional minerals. Limestone is the root of many crystals including, agate, calcite, dolomite, lapis and Septarian, just to name a few. Red and tan stones for the Base or Root Chakra, orange for the Sacral/Spleen Chakra and so on. Therefore, the color of the limestone can help assist with colors of the Auric field and Chakra centers. Many limestones exhibit different colors, especially on weathered surfaces. Shells of sea animals form grains in limestone that promotes the growth of cement crystals around themselves. Limestone is also classified as a young marble formed from the consolidation of seashells and sediment. The stone has the unique property of retrograde solubility, meaning that the stone is less soluble in water as the temperature increases. Most Limestone starts as the floor of shallow tropical seas and can be seen in parts of the tropics that are only 30 to 40 years old. Limestone makes up about 10 percent of the total volume of all sedimentary rocks. The secondary source of calcite is the shells of sea animals and corals. The main source of this calcite in limestone is speleothems such as stalagmites and stalactites. Limestone often contains variable amounts of silica in the form of Jasper or Flint, as well as amounts of clay, silt, and sand as disseminations, nodules, or layers within the rock unit.
Limestone is a sedimentary rock composed mainly of the mineral calcite, which is a crystalline form of Calcium Carbonate (CaCO3).
