Let Me Tell Ya About The Birds and The Bees and The Flowers and The Trees

I know it has been a few weeks since I have posted anything. For this I apologize. No excuses given, just an apology. However, one thing that has been on my mind almost incessantly over the last couple of weeks is ecology. It's that branch of life and environmental sciences which looks at how biological life interacts with other members of the habitat. This can even include non-biological life such as soil, water, and climatic patterns.

Why has it been on my mind? In two words: it's fascinating! I have long been interested in these interactions and currently my work at Freshkills Park as well as my personal reading have reminded me that this is something I am deeply passionate about. The wonderful thing about ecology is that it exists in some form on every scale. Whether in an urban environment, the tropical forests, or coral reefs, ecology is present.

Some scientists focus on the whole ecosystem - interested in the big picture - while others are fascinated by narrower focal points, either between two species or a single group of organisms - such as plants - and how they interact with the rest of the system. My personal interest definitely focuses on plant ecology as I understand the singular importance that plants play in most ecosystems. You take out the plants endemic to a specific habitat and you have yourself a completely different ecosystem. Even switching which plant species is dominant within the ecosystem can alter the overall interactions inside the system.

Ecology is complex. Studying one system in one part of the globe does not mean you can make predictions about what will be going on in the same system located in a different region. Conditions are altered on a near continuous basis. What we know about an ecosystem now did not hold true for that system even 50 years ago. You add the fact that humans have had some sort of impact on every ecosystem and on most species and you are left with a royally complicated situation. But that is what is fascinating to me about it. Ecology is studying how biological life and its interactions with local physical and chemical elements are changing in real time.

You might say, "Look at what humans have done to the planet. It is ruined! Why would you want to actually know how bad the damage is?" You would be partially correct that humans have wreaked havoc with the ecosystems of this planet. Life has always dealt with havoc-induced changes though. Ecology can not only study ecosystems so we can be informed about how we must alter our activities, but ecology can also study how ecosystems are responding to our inputs. It's not always negative! Plus, we are learning from some of our mistakes and we have been giving back to nature. This dynamism is what makes life interesting.

There are no links on this post to back up my claims. This is just from my heart. You may not get it but so what? We all have our reasons why the environment means something to us. Ecology is my reason. What's your reason?

Biodiversity Preserved

I am a huge advocate for biodiversity. I believe our planet's greatest strength can be found in the range of life that is found on its surface or below the waters. Healthy biodiversity increases the chance that biological life would continue after a significant natural cataclysm. We value diversity in our own DNA supply chain because it reduces the risk of succumbing to a deadly disease, birth defects, etc. The number of different species on this planet (bacteria, protists, fungi, plants, animals, and even viruses) can and should be considered a barometer of the health of the planet's DNA supply chain.

There have been five times in the Earth's history that a huge portion of species went extinct, with the first great extinction event wiping out 96% of life. Scientific evidence is mounting that we are in the throes of a sixth extinction event, this one largely driven by us (more on that in a later post). Despite the stresses we have placed on plant and animal species, we have taken action to preserve many species that are recognized as endangered. Thanks to the Endangered Species Act in the United States and similar programs around the world, plants and animals on the brink of vanishing are given a metaphorical lifeline that helps to reduce the stress on them and allows the species to recover to healthier populations. I would like to provide links that highlight some of the successes here.

White Rhinoceros

Golden Lion Tamarin

Gray Wolf

Eggert's Sunflower

Tennessee Coneflower

There are many more species that are recovering thanks to programs/management plans designed to protect species and help them propagate. The success stories are proof that humans can do good things for the environment. Biodiversity is a thing of beauty that we should work hard to protect.
