The first episode featured an interview with legendary natural history broadcaster, Sir David Attenborough, who spoke about the need to live “more economically than we do”. Here are some of the possible solutions he put forward to helping solve the climate crisis:

• ‘We must learn to live more economically than we do’
• Governments need to work together rather than separately
• Countries should pay Brazil to not cut down their rainforests
• Creating sanctuaries to prevent overfishing will protect our seas
• We need to find a way to transport renewable energy cheaply over long distances
• Re-wilding
• Raise our awareness of how we are part of nature and live closer to it

Episode one, part two was with Crystal Chissell, vice president of operations and engagement at Project Drawdown – a non-profit US organisation looking into existing climate solutions. These were some of her suggestions:

• Switch your lights to LED bulbs
• Eat a plant-rich diet
• Opt for alternatives to driving petrol cars when you can, such as an electric car
• Support land conservation
• Join others
• Embrace change: ‘Just because we have to do things differently, it doesn’t mean things will be worse. It might be in some cases, our situations improve’
• 'Communicate with those in power, those who are selling us products – let them know that you want them to solve these problems'
• 'Reconnect to our belief in the goodness of people when we feel discouraged'

One thing we can change as individuals, is how we talk to each other. This was explored in the episode with climate professors Lorraine Whitmarsh and Katherine Hayhoe about how to understand climate denial, and why people may feel negative or apathetic about change. Here were some things we learned:

• Have more conversations about climate change face to face
• Friends and family often have more power to make you change rather than any big celebrity
• Look at who you are voting for
• Focus more on high earners - who can have higher carbon footprints
• Ask yourself, ‘What does this mean for me?’ Then ask yourself what you can do about it

In part one and two of episode four, we heard about how we can make a big impact by reconsidering the things we buy and giving our possessions a longer lifespan.

Here were some of the things we learned from The Repair Shop’s Jay Blades, Selfridges chair Alannah Weston, Sara Divali from Hubbub and climate experts Prof John Barratt and Dr Nicole Koenig Lewis:

• Rent goods especially furniture or goods in fashion
• Share goods - like sharing cars
• Buy less and buy better, more durable products that can have more than one owner
• Find out where products are being made
• Compare products online
• Repair, reuse, upcycle and repurpose products to extend the lifespan
• Buy second hand
• The government could demand higher standards on products
• Carbon taxes on products
• Border carbon adjustments

Read the small print

• Don’t believe everything you read: What does 'we’re striving for highest sustainability goals’ – really mean? Look for proof to back up a company’s claim
• Buy into a brand not a product who are transparent about their overall sustainability practices
• Beauty products will often have green packaging or packaging featuring ‘nature’ including words like ‘natural’ while having no sustainability benefits or organic ingredients
• Compostable plastics are often used as a green alternative for packaging or things like coffee cups. The claim is misleading as the plastics would need to be sent to an industrial composter to biodegrade and most are thrown in normal waste
• Products are often labelled with ‘recyclable’, this means that they can in theory be recycled rather than they are in practice widely recycled
• Fashion labels will often produce sustainable capsule collection and while this is a brilliant step in the right direction, this is usually a very small part of the company’s overall collection and doesn’t mean that the brand is working towards ambitious sustainability goals

It can sometimes be tricky to find hope amidst all the news about climate change. But in episode six, supermodel and businesswoman Lily Cole and teenage environmental campaigner Bella Lack explained how we can stay optimistic. These were some of their solutions that we can do as individuals:

• Recognise the power of people and the collective
• Work less, sleep more
• Recognise there’s no such thing as a perfect environmentalist and don’t berate yourself
• Fly less. Use the train more
• Move your bank account to an ethical bank
• Spend more on better quality goods and keep them for longer
• Consider reducing your intake of animal-based products such as meat and dairy

In episode two, we heard from Hollywood actor Idris Elba and his wife Sabrina Dhowre Elba, who are UN Goodwill Ambassadors for the International Fund for Agricultural Development. They shared some personal insights about inequality, the state of our global food systems and how we can all do something to help:

• ‘Each one, teach one’ – educate yourself and others about the issues
• Find better food storage solutions for rural farmers in developing countries, to combat food waste
• Increase the visibility of people who don’t have much and are impacted by climate change
• Fund and build irrigation systems which use less water
• Use climate-proofing solutions in vulnerable locations
• Develop more respectful relationship with food
• Grow your own
• Improve soil quality - what you put in the soil, you take from the soil
• Spreading a positive message rather than scaremongering
• Educate women and girls to help manage population growth

In part two of our episode on food, we heard from Indra Thillainathan, an agriculture and land use analyst at and Dr Rosemary Green from London School of Hygiene and Tropical Medicine. These were some of the suggestions we heard in the episode:

• Think about eating healthily by increasing your intake of lentils, chick peas and peas which are good proteins
• Consider reducing the amount of meat and dairy you consume. Could you try vegan for one meal a day, or switching to a meatless meat? And if you do eat animal products, try buying better quality.
• Try choosing local produce
• Swap one thing a week in your weekly shop for a sustainable item
• Grow and eat seasonal food
• Reduce household food waste

• Increase the amount of fruit and veg grown in the UK and import less
• Free up 20 percent of our pastureland in the UK for re-wilding
• Diversify crops
• Restore more peatland
• Improve the diets of cattle so they burp less
• Give farmers a subsidy for providing environmental goods
• Government awareness campaigns and better education
• Better labelling on foods to show the carbon footprint
• Standardised metrics on the emissions intensity of foods
• Incentivise shoppers to change their behaviour (like with the 5p plastic bag charge)

The music industry is a significant part of the UK economy, so we spoke to Edwin Congreave from Foals (pictured on keyboard) about the climate impacts of touring. Here were his thoughts on how touring may need to change in order to lessen carbon emissions:

• Bands to tour differently, not flying on world tours in the same way
• Watch more music online
• Use green energy at venues, gig and festivals
• Bring fewer people on tour and hire more local, tech talent
• Better public transport to out of town venues so people don’t have to drive
• More city centre big venues
• Freight gig kit rather than fly it

In the same episode as Edwin, the What Planet team spoke to Chiara Badiali from Julie’s Bicycles. She focuses on getting the music industry up to speed when it comes to sustainability. These were her solutions:

• Commit to action by writing down an environmental policy or a commitment action plan.
• Measure and report your business carbon footprint - such as energy bills and travel - so that the industry is accountable and transparent
• Work with experts from outside your industry to keep learning and to help make key decisions
• Switch to renewable energy and use less of it
• Consider shifting your savings and pensions into green investment funds
• Make it easier for audiences and fans to do the right thing, such as providing reusable cups at venues or bundling festival tickets with coach tickets to encourage public transport use
• Think about different kinds of business models - whether that's more live streaming, more residencies, or slower touring
• Speak out and be brave, even though we'll get accused of hypocrisy by people who do not want to engage with what we're saying
• Use your industry’s voice to ask for better policies from government
• Find environmental campaigns and charities and causes to support
• Support artists who speak out: So often this is all just put on the shoulders of artists. But to really empower their voices, the industry itself needs to come together to act.

One of the world’s most influential voices on climate is former UN climate chief Christiana Figueres – who with political strategist Tom Rivett-Carnac, helped bring together world leaders for the historic . Here are her thoughts on how individuals can influence political leaders around the world.

• Use citizen assemblies to advise governments
• Don’t leave it up to federal governments to solve climate change - all human beings need to be on board
• More litigation cases can force governments to change laws

We also heard from some of the world’s leading young activists; Jamie Margolin, an American climate justice campaigner and the co-executive director of Zero Hour; Vanessa Nakate, a Ugandan climate justice activist and founder of the Rise Up Movement; and 15 year-old environmentalist, Holly Gillibrand, who was one of the youngest climate activists in the UK when she first began school strikes in the Scottish Highlands where she lives. They gave some thoughts on how to make change happen:

• Question your employers about their practices
• Hold corporations to account
• Become allies with your co-workers and push for change
