League for Green Leaders


Join us Saturday April 27 from 9AM to Noon at Venture 13. Discover how our natural heritage systems work. Learn why biodiversity is important for our health and wellbeing. Learn indoors and apply your citizen science digital skills outdoors. Protect our local wetlands, forests, rivers and creeks. Work with nature to: 

  • reduce soil erosion;
  • remove water pollutants; 
  • decrease local flooding; and
  • lessen the threat of wildfires 

Bring your own snack and the right indoor and outdoor footwear. We will provide the water. Weather permitting, we will map trees, test water quality and locate invasive species for removal.

A quick 3D poster design project related to natural heritage systems for a Grade 9 Communications Technology class in Ontario could involve the following steps:

1. Choose a specific natural heritage system in Cobourg Ontario.

2. Gather information and images related to the chosen theme to understand its significance and challenges.

3. Quickly sketch out a few design ideas on paper.

4. Utilize user-friendly 3D design software like Blender or Tinkercad to create simple 3D models that represent elements of the natural heritage system.

5. Create the Poster Layout by arranging the 3D models on a digital poster canvas, adding text and other design elements (The Life of a Box and Graphics Packaging seedling event)

6. Explain how your poster promotes natural heritage conservation.

Remember, the key is to keep the design simple and focus on conveying the message effectively within the one-hour timeframe. For inspiration and guidance, you can refer to resources like the “Best Practices Guide to Natural Heritage Systems Planning” by Ontario Nature² and various online tutorials for quick 3D design projects⁴⁵⁶.

Jennifer Hillmer, Invasive Plant Management Coordinator at Cleveland Metroparks, Jennifer helped establish and directs a district-wide management program to find, evaluate, prioritize, and remove invasive plants from the 25,000-acre park district. She has worked for the Ohio DNR, The Nature Conservancy, and The Holden Arboretum in Kirtland, Ohio. She is a founding member of the Ohio Invasive Plants Council and the Crooked River Cooperative Weed Management Area (Ohio), a former board member of the Midwest Invasive Plant Network, and a tireless advocate for good recordkeeping.

Hosted by ITU, Thomas Basikolo on the tinyML Challenge is an action-oriented platform within the United Nations, seeking practical applications of AI to drive progress towards the UN Sustainable Development Goals. In the culmination of the 2023 tinyML Challenge, three distinctive problem statements were proposed to the global community of developers to advance solutions for: smart weather stations, plant disease detection, and wildlife monitoring using tinyML solutions. from ITU set the stage, emphasizing the significance of the tinyML Challenge and the productive collaboration with the tinyML Foundation. This challenge spanned from June to November, presenting participants with intriguing problem statements and an array of hardware resources to explore and use for their solutions kindly sponsored by Arduino and Seeed Studio.

Did You Know?

Packed into standard shipping containers and placed end-to-end, municipal solid waste generated in one year would wrap around the globe 25 times. This is unsustainable! What is your community doing to target waste reduction? -

Adopting sustainable practices, whether large or small, can have significant impacts in the long run. If every office worker in the United Kingdom used one less staple a day by using a reusable paper clip, 120 tonnes of steel would be saved in one year.

So far in 2022, Depave Paradise has depaved 15 asphalt pavements! Since 2012 this group has completed 80 projects across 32 Canadian cities covering 76,384 square metres of unused paved surfaces into beautiful community green spaces with native grasses, flowers and trees. What an amazing sustainable action to capture carbon, a Greenhouse gas, and create a welcoming ecological ‘paradise’ for our monarchs and bees and of course, for us. Well done. This is a project of Green Communities Canada.

In 1993, the Convention on Biological Diversity put the precautionary principle to work.

In 1987, the Brundtland Report consolidated decades of work on sustainable development.

The First World Climate Conference happened in 1979 and opened up the science of climate change.
