April 22 - International Mother Earth Day

Posted on April 22, 2020

Gaia is the Greek version of
Mother Earth
There are some people who seem to think that caring about the environment and celebrating Earth Day puts wildlife and open spaces ahead of "more important" things - like money! Earning! Profits! Stock prices!

But of course nothing could be more important than the health of the environment. People can't drink profit and can't breathe stock prices. It doesn't matter how much money you have, if there is nowhere you can live, no reasonably clean water to drink, no reasonably clean air to breathe, no oxygen in the air, no land on which to grow food. 

Prithvi is the Hindu Earth goddess

Also, the health of the environment affects the health of animals, and the health of animals affects human health. 

And human health is important to the economy.

Mother Nature is teaching us this lesson right now - the hard way! COVID-19 is a new disease to humans - a disease that crossed over to us from a non-human animal (probably bats, possibly through a "middle-man" sort of animal such as a pangolin). And this disease is not only infecting many, many people the world over, it is also causing a lot of deaths and a tremendous amount of economic damage.

Houtu is a kind of Mother
Earth in Chinese mythology.
According to the United Nations page on Mother Earth Day, a new infectious disease emerges in human populations about one per every four months. And 75% of these emerging diseases come from non-human animals!

A healthy ecosystem with a lot of different plants and animals actually protects us from these diseases. It's a lot harder for germs to get from organism to organism in a healthy and diverse ecosystem. 

Spider Grandmother is an Earth goddess in
some Native American traditions.
So, protect the economy - jobs, profits, stock prices, etc. - by protecting the Earth!




December 6 – Ever-Guarding the Everglades

Posted on December 6, 2017

Most National Parks keep 
safe amazing natural structures such as rock arches, deep canyons, geysers and hot springs, cliffs and peaks. 

But in 1947, one of the largest National Parks in the United States was created to keep safe a fragile ecosystem: the Everglades National Park, in Florida.






The Everglades is made up of a series of wetlands. Swamps and streams, ocean inlets and marshes, mangrove forests and estuaries...

The Everglades are home to wonderful and unique animals:

Incredible large creatures such as the American crocodile and the American alligator...



Endangered creatures such as the Florida panther...






The slow and peaceful manatee...







And hundreds of species of birds and fish, and other creatures.


In order to enjoy the Everglades, many people hike or bike, row or ride a tour boat...

February 2 – World Wetlands Day

Posted on February 2, 2016

Wetlands are really, really important to the Earth's biosphere. These ecosystems are land areas that are saturated with water (either all the time or just part of the year); the plants that grow in wetlands are adapted to wet soil, and many different sorts of animals live in wetlands as well.

Wetlands are considered the most biologically diverse of all ecosystems. That means that there are more different kinds of plants and animals in wetlands than there are in either fully aquatic or drier land ecosystems. And some animals that only live in wetlands part-time use those areas to breed, feed, or even “just” rest. (Resting is important for migratory birds!)

Wetlands often act as reservoirs that hold fresh water. They often act as filters, because wetlands plants remove impurities and excess nutrients from water.

Do I need to point out that anything that is important to the Earth's biosphere is also important to humans? According to the World Wetlands Day website, more than a billion people make a living from wetlands! 

Here are some types of wetlands:

swamps

Swamps are wetlands that are forested. Swamps can be fresh water, brackish water (somewhat salty), or seawater (very salty).


Mangroves are adapted to having "wet and salty feet."
Swamps are often pictured as kind of sinister and creepy.


marshes

Marshes have few if any woody plants – and any woody plants that occur are low-growing shrubs. So, no trees. Usually, marshes are grassy.


bogs

Bogs are characterized by peat – dead plant materials that have accumulated and made the water acidic.


Bogs are sometimes called mires, quagmires, or muskegs. We talk about getting mired in work, bogged down by a problem, or stuck in a quagmire (a tricky situation that is difficult to solve) because sometimes people or animals get stuck in bogs or mires.

Don't worry; this horse WAS pulled to safety.

fens

Fens are also mires, but they are alkaline rather than acidic. Rather than coming from peat (dead plant materials), the waters of a fen are full of minerals and often bubble up from springs.


Even though wetlands are so important to food chains, biodiversity, and even human economies, some people view them as just wasteland. They sometimes want to drain such areas so that they can build more stores and apartments and roads. We have lost more than 64% of the Earth's wetlands since 1900.

Yikes!
