"Helio da Silva, a retired business executive from Brazil, single-handedly planted over 41,000 trees in his hometown of Sao Paolo over the last two decades.

Flying over the Brazilian metropolis of Sao Paolo, it’s tough to miss the 3.2-kilometers-long and 100-meter-wide green strip of trees wedged between two of the city’s busiest roads. It is known as Tiquatira Linear Park, and it is the work of a single man who worked tirelessly for over 20 years in order to transform a previously dilapidated area into an actual jungle within the urban jungle that is Sao Paolo. Originally from the town of Promissao, about 500km from Sao Paulo, Helio da Silva was a successful business executive for many years, but after retiring, he took it upon himself to transform the degraded banks of the Tiquatira River into a green oasis for his community. He started planting trees there in 2003 and hasn’t stopped since.

73-year-old da Silva recently told AFP that he wanted to leave a legacy to the city that adopted him decades ago. Within the first four years of his epic project, he single-handedly planted 5,000 trees in an area that had long been abandoned and known to be frequented by drug dealers and users. His impressive feat prompted the municipality of Sao Paolo to recognize his efforts and acknowledge the area as the first linear park in Sao Paulo. This only emboldened da Silva, who continued planting native trees.

By 2020, Helio had planted more than 25,047 trees over a 3.2-km-long area, achieving a survival rate of 88 percent. For every 12 trees, he planted a fruit-bearing species in the hopes of attracting birds and animals to his green oasis. His bet paid off, as according to the municipality, 45 types of birds have been identified in the park. Today, the Tiquatira Linear Park numbers over 41,000 individual trees, and Helio da Silva doesn’t plan on stopping planting until he reaches at least 50,000 of them.

“My motivation comes from the trees themselves because trees give us flowers and fruits, absorb rainwater, attract birds and provide us with wonderful shade and fresh air,” da Silva told Common Earth.

The retired executive estimates that he spent about $7,000 per year on his tree-planting efforts since 2022, but the way he sees it, it was a worthwhile investment for himself, his family and the whole of Sao Paolo. Plus, he saved a lot of money by planting the trees himself.

Once labeled as crazy for spending most of his time planting trees in an area most people avoided, Helio da Silva is now hailed as a local hero. He sometimes receives help from like-minded nature lovers, but he is still the driving force behind this amazing project. Every Sunday, he comes to Tiquatira Park to plant more trees.

Over the years, the city gym and playground equipment, tables, benches, toilets, and Tiquatira Linear Park eventually became one of Sao Paolo’s most popular areas."

Note: ONE SINGLE PERSON CAN MAKE A SUCH A DIFFERENCE

"Heat stored underground in caverns can be set aside in Finland’s summer months to be re-used during frigid winters thanks to a state-of-the-art ‘seasonal energy’ storage facility.

Slated for construction this summer near Helsinki, it will be the largest in the world by all standards and contain enough thermal energy to heat a medium-sized city all winter.

Thermal exchange heating systems, like those built underground, or domestic heat pumps, are seen as the most effective way available of reducing the climate-impact of home heating and cooling.

Their function relies on natural forces or energy recycling to cool down or heat up water and then using it to radiate hot or cold energy into a dwelling.

In Vantaa, Finland’s fourth largest city neighboring the capital of Helsinki, the ambitious Varanto seasonal energy storage project plans to store cheap and environmental friendly waste heat from datacenters, cooling processes, and waste-to-energy assets in underground caverns where it can be used to heat buildings via the district heating network whenever it is needed.

In Finland and other Nordic countries, the heat consumption varies significantly between seasons. Heat consumption in the summertime is only about one-tenth of the peak load consumption during the cold winter months.

Varanto will utilize underground caverns equal in space to two Maddison Square Gardens—over a million cubic meters—filled with water heated by this waste heat and pressure that will allow the water to reach temperatures of up to 300 degrees Fahrenheit without the water boiling or evaporating.

“The world is undergoing a huge energy transition. Wind and solar power have become vital technologies in the transition from fossil fuels to clean energy,” says Vantaa Energy CEO Jukka Toivonen.

“The biggest challenge of the energy transition so far has been the inability to store these intermittent forms of energy for later use. Unfortunately, small-scale storage solutions, such as batteries or accumulators, are not sufficient; large, industrial-scale storage solutions are needed. Varanto is an excellent example of this, and we are happy to set an example for the rest of the world.” ...

“Two 60-MW electric boilers will be built in conjunction with Varanto,” adds Toivonen. “These boilers will be used to produce heat from renewable electricity when electricity is abundant and cheap. Our heat-producing system will work like a hybrid car: alternating between electricity and other forms of production, depending on what is most advantageous and efficient at the time.”

... Construction of the storage facility’s entrance is expected to start in summer 2024, while it could be operational as early as 2028."

Munich-based foodtech startup Planet A raises $15.4m for climate-friendly cocoa alternative

The company uses a proprietary fermentation process to turn locally sourced ingredients like oats and sunflower seeds into its patented “ChoViva” product — a cocoa alternative that can be used to make chocolate, but doesn't actually contain any cocoa beans.

Cocoa beans can only grow in specific climates, which are now under risk. (Most of these risk are due to climate change, a plantation economy which exploits farmers, and inequitable pricing of raw produce compared to global chocolate prices. Child slavery is also a problem - a link to back up granny's rant)

The price of cocoa has risen to its highest level in over 46 years. As a result, chocolate makers are in search of a cheaper alternative that can mimic the taste — and cofounder Sara Marquart says that ChoViva costs less than many sources of traditional cocoa.

The company currently has partnerships with chocolatier Lindt, which uses ChoViva in its new vegan range, and flight provider Lufthansa. 

This is why art is important, in case you were wondering.

And kids will be so productive if you make it a game. I bet at least 50% of the kids who met this sculpture went and intentionally hunted for litter to feed it.
