Picking up where it left off in 2019, the organization Green Roofs for Healthy Cities focused on resilient cities at its annual “Cities Alive” conference this week in Philadelphia. Nothing would stop me from making the trip east this year to learning from my colleagues about the latest green roof initiatives and building methods.
I first discovered Green Roofs for Healthy Cities in 2006. I visited Manhattan for the opportunity to work for a day with Leslie Hoffman of Earth Pledge NYC. We had met earlier in San Diego at a People for Livable Places event. I became enthralled with green roofs, but I had no idea at the time how to build one or even what they really looked like.… Read More
In my spare time, I read science articles. Doesn’t everyone?
In this case, the headline got my attention: “Plants aren’t good at photosynthesis. We can do it better.”
This didn’t make sense to me. The reason plants grow and thrive is photosynthesis. It’s life and death for plants. The article was
written by Dr. Raffael Jovine, a scientist who is the author of the new book “How Light Makes Life: The Hidden Wonders and World-Saving Powers of Photosynthesis.”
I read more and thankfully, Dr. Jovine isn’t a hater. Far from it. His book explores how photosynthesis was first discovered and understood by humans, how it works, our planet’s reliance on photosynthesis for nearly all life, the economic value of photosynthesis, and how we can use photosynthesis and plants to save our environment and solve many other complex problems like hunger, healthcare, and equity.… Read More
When we first installed our green roof at Good Earth Plant Company fifteen years ago in 2007, all the information about the long-term impact came from Europe. There weren’t many green roofs in the United States, just a few in the northern United States and southern Canada. There were very few studies conducted on them, none in our Southern California region.
Times change, and we are much more enlightened about the positive impact of green roofs on the immediate environment and their contribution overall. We love green roofs and everything they stand for at Good Earth Plant Company. We have now built several green roofs in the decade since then, from private homes in Del Mar, Encinitas, and Santa Monica, to the “Fallen Star” art installation at UCSD, to the spectacular green roof at Sharp Memorial Hospital in Kearny Mesa.… Read More
The first Earth Day took place in 1970. It is now an annual event celebrated on April 22 in more than 192 countries each year in hundreds of communities in the United States
Guess which city has the BIGGEST Earth Day event? Yes, it’s right here in San Diego. The annual Earth Day Fair 2022 returns to Balboa Park after two years off due to the pandemic this Sunday, April 24. It is the largest free, all-volunteer Earth Fair in the United States. Organizers definitely need both volunteers and cash donations. Please help if you can.
This year’s Earth Fair features 300 exhibitors, the Children’s Earth Parade from 9:30 to 11 a.m.,… Read More
Some of my favorite quotes are about trees. I love what they express about the power of nature, optimism, and time.
“The true meaning of life is to plant trees, under whose shade you do not expect to sit” – Nelson Henderson
“Someone is sitting in the shade today because someone planted a tree a long time ago” – Warren Buffett
“He who plants a tree, plants a hope” – Lucy Larcom
“The best time to plant a tree was 20 years ago. The second-best time is now” – Chinese proverb
I love all things trees. I always have. One of the very first blog posts I ever wrote was about the magic of treehouses in September 2013.… Read More
Many families usually make plans to put up their Christmas tree this time of year. But when’s the last time anything seemed normal?
Like so many other goods right now, the supply chain problems slowing down the delivery of so many products affect Christmas trees. Whether you prefer a real Christmas tree or an artificial Christmas tree, it’s more complicated and more expensive in 2021.
For California residents – and most people in Western states – the supply chain issues combine with inventory destroyed by western wildfires in tree-growing states like Oregon. Rising temperatures also create problems for tree farmers. The result: tree costs are up about five to ten percent.… Read More
In a previous life, I must have been some kind of animal that lives in a tree. I love all things trees. I always have. One of the very first blog posts I ever wrote was about the magic of tree houses in September 2013.
Trees are at the top of my consciousness right now following my vacation trip to the Pantanal region of Brazil. It’s such a different experience being immersed in dense forests of trees, especially the amazing and unusual types of trees we saw in Brazil.
Back at home in San Diego, I’ve been thinking just how valuable trees are to us in our hot, dry Mediterranean climate.… Read More
It feels like every news broadcast I watch has been filled with more and more tragic news, from devastating tornadoes in Oklahoma and Texas, to school shootings and terrorism attacks all over the world. I feel so helpless to do something to help or change the situation. Some of the heartbreaking news is man-made, and some of it beyond our control.
In particular, the weather has been so crazy. Nightly weather broadcasts have taken on a sometimes frightening appearance. Happy broadcasters used to point to smiling-faced sun cutouts and cheerfully report holding an umbrella during rainy days. No more.
The weather around the world has seemingly taken on a harsher quality.… Read More
Remember when the terms “Global Warming” and “Climate Change” were first mentioned? Now it’s commonplace. I just read how a research meteorologist at Scripps Institution of Oceanography is suggesting that big cities in North America and Asia may generate enough heat to warm areas as far north as Canada and Siberia as much as 1.8 degrees.
In general, the heat gathered from the urban heat island effect rises and travels upwards and its energy may change high-altitude currents in the atmosphere that dictate prevailing weather. Meteorologists have known that cities are warmer than rural areas with cars, buildings, asphalt and roofs that absorb heat.… Read More
