Doug’s love for wolves began when he was a child. He read books about them and puzzled why humans could wipe out an entire animal species. He had to wait until he was 18 to take a volunteer position to help raise wolf pups in Indiana. He went to university to study biology and spent his summers working with wolves. He finished his studies in 1994 and joined the Yellowstone Wolf Project, becoming project leader in 1997.killed In 1995, almost 60 years after the last native wolves were killed, 14 wolves from Canada were released into the park’ Doug until he retired in 2024, watched the positive influence the reintroduction of wolves had on the ecosystem of the park. The number of elk fell in the park - which they had expected. The wolves changed the eat habits of the elks- they now now grazed and browsed instead of staying in one place. With less elks the land had a chance to recover. Trees which had been stunted in their growth now grew into dense forests. The berries and the insects from the trees brought back the birds Beavers flourished, their dams created deep pools and caused the rivers to slow down and meander The new trees stabilised the riverbanks The wolves had changed the landscape itself.

Observe and interact Catch and store energy Obtain a yield Apply self regulation and accept feedback Use and value renewable resources and services Produce no waste Design from patterns to details Integrate rather than separate Use small and slow solutions Use and value diversity Use edges and value the marginal Creatively use and respond to change Perrine and Charles Herve-Gruyer in 2003 bought a small farm in a village called Hellouin, in France. They were determined to start with goals of self-sufficiency and wanting to grow healthy organic food without the use of chemicals or machinery. Few people had heard of organic farming. This they tried for 5 years but the yield did not make enough money to support the family. An email in 2008 ,about Permaculture, from a friend, changed everything. In the wild twice as much biomass , or plant material, grows naturally compared to farmland without the use of machinery or fossil fuels. It involves observing and learning from nature -how it makes new soil, protects and saves its water resources and how it adapts to climate. Perrine went on a Permaculture course in the UK that winter. They introduced vegetable beds which they did not dig but covered in mulch -plant cuttings and dead leaves. This protected the soil from drying out and made new soil as it rotted down. The result was more worms , fewer slugs and the vegetables grew better. They planted different crops close together, fitting them four times closer then before. They planted an edible forest with mushrooms, berries, fruit bushes and nut trees. They dug ponds, with island gardens in the middle, so the water reached the plants through the ground- no more watering the crops with hoses or watering cans. In their polytunnels they kept hens which eat the unwanted scraps slugs and snails, produced eggs and fertilized in the form of droppings. The French National Institute of Agricultural Research began a scientific research. After 10 years their 6,500 square farm had been transformed into an enormous garden with crops (800 varieties of vegetables, fruit and herbs) , wild flowers, singing birds, ducks, frogs and insects. The Herve-Gruyer family wanted to create something beautiful and the Earth gave back back to them in abundance. The farm, using the Permaculture ideals, produces 10 times more than a normal farm of a similar size. Sources Wikipedia Earth Heroes Lily Dyu and Amy Blackwell

Felix is a German environmentalist and founder of the international tree planting and environmental advocacy organization Plant-for-the -Planet. Aged just 9 he was inspired by Wangari Maathai, from Kenya, who inspired a group of women to plant 30 million trees . Aged 9 he gave his first presentation to his class. His classmates clapped and cheered when he planted his first tree. News of the project spread and in April 2007 with help from his family he launched his children’s tree planting campaign. Aged 10 spoke in the European Parliament. In October 2008, with his sister Franziska and Gregory they held a special week-end. 100 children attended to train to be Climate Justice Ambassadors. After just 3 years the initiative resulted in 1,000,000 trees being planted… Met Wangari at UN meeting in New York. They combined efforts. By February 2011 over 12 billion trees planted. 2012 launched Die Gute Schokolade - Change Chocolate bar. The chocolate is Fair Trade and carbon neutral. For every 5 bars bought a tree is planted in Mexico (every 15 seconds a tree is planted). Aged 13 attended the UN General Assembly. Today Felix leads an organisation with 130 employees. Their target is 3,000,000,000, 000 trees ( 3 trillion) by 2030. His/their target is to help slow down climate change. Sources Wikipedia Earth Heroes by Lily Dyu and Amy Blackwell

The two sisters were inspired by a school lesson about people who changed the world- Nelson Mandela and Martin Luther King. They had already experienced swimming in a bay in Bali and seeing plastic bottles, bags and bits of plastic floating on the water. They went home and did some research. Their research revealed that many countries had banned plastic bags. Why not Bali? They would try to solve the plastic pollution problem on the island by persuading people to stop littering… With 6 friends they started a campaign to ban paper bags… They named it** Bye Bye Plastic Bags** The first thing they did was to set up an online petition asking the governor of the island to support the ban. On day one they had 6, 000 signatures. Over the next few months this rose to 77,000. They asked the airport manager to help and they gained another 10,000. By this time their village of Deso Perenon had reduced plastic bag usage by 60%. The governor had still not responded. They learned, after a visit to the National Gandhi Museum, he had called a strike to force change. They also decided to so something similar-publicly fast from sunrise to sunset - he finally responded. After meeting them he signed an agreement to work towards a plastic-bag free Bali. They now involved businesses -shops, hotels and restaurants. In June 2015 the government announced that by 2018 plastic bags would be band… In 2015 the sisters w ere invited yo give a TED (Technology, Entertainment, Design) talk in London. By January 2018 Bali failed to reach target so the government declared a Garbage Emergency -officials 700 cleaners, with 35 trucks, to clear 100 tonnes of debris each day. In December the government announced single-use plastics would be banned from the island from July 2019. The sisters won many awards. Today Bye Bye Plastic Bags is a global youth movement in 45 countries. Sources Wikipedia Earth Heroes by Lily Dyu and Amy Blackwell

Protecting the world’s forests is crucial for the climate. Forests absorb vast amounts of carbon dioxide and can be a source of greenhouse gas emissions when destroyed or damaged. Logging in deforestation refers to the practice of cutting down trees for commercial purposes mainly the timber industry. The impact of deforestation, if not controlled, can be devastating. On average for every tonne of wood extracted 6 tonnes (1:6) are damaged or destroyed. It can rise to 1:20. There are a number of ways of stopping it being so devastating. a logger could make a more accurate assessment of tree’s quality -a’plunge cut’. A chainsaw is driven into the base of the trunk to reveal if it is hollow without killing it. n be dropped where it will do least damage to its neighbour. instead of a wide skidway leaving a trail of destruction it can be narrow and sensitive to other trees OR a ‘logfisher’ -an adapted crane with long cables could ‘fish’ the timber out with less skidding logging roads could be reduced to 15 metres instead of 30 metres Combine all these habits and more trees will be left standing to hold more carbon and potentially grow on to be of valuable to the logger (Chapter 11 - Good Logging- 39 Ways to save the Planet by Tom Heap)

We have been accustomed to seeing roofs covered in solar panels( using the rays of the sun) to heat people’s homes. We have seen them built on large areas of land ( car park size). These are small scale compared with Floating Solar- solar panels on a body of water as large as a reservoir or lake. Across the world, especially in China, these have been developed. See the long lists of advantages:- 1.no land occupancy 2. water conservation and quality 3. increased panel efficiency 4. tracking 5. environmental control 6. using areas already exploited by human activity 7. using power plants Disadvantages anchorage maintenance new technology required significant increased corrosion resistance waves (open sea) (Read detail about each) This is one of the major ways forward to counter Climate Change Sources Wikipedia 39 Ways to Save the Planet by Tom Heap

BladeBUG will do the maintenance on the wind turbines at sea. The vision of Chris Cieslak, BladeBUGs founder, is to keep all humans on shore. An autonomous vessel would leave port carrying the BladeBUG. A drone would be sent to make an initial inspection from the air. On its return to the boat it would collect a BladeBUG robot and ferry it to the work area. Source 39 ways to save the Planet

Vertical farming is where crops are grown on top of each other than in traditional horizontal rows. This is happening both on the land ( indoors) and in the sea. Using less space the yield is higher. Read description and look at the two pictures. Greenwave have developed a sustainable agriculture technique called vertical underwater farming or regenerative ocean farming.The company is growing a range of seaweed types like kelp and shellfish, plus mussels and scallops on a rope scaffolding system under the sea. Kelp is one of the fastest growing organisms on the planet and can be repeatedly harvested for at least seven years. Source World Economic Forum

Climate change has resulted in AQUACULTURE being seriously considered. Man is seeking to grow crops under water especially SEAWEED This means the plants are grown without soil, in a nutrient-rich solution to deliver water and minerals to their roots, in a controlled environment. No pesticides are needed. The start up that believes seaweed can change the world. Source World Economic Forum
