Our Lives Without Fossil Fuels Can we live without fossil fuels and produce enough energy without oil? A sustainable future lies in increasing use of renewable energy, such as wind and solar energy, says Peter Head. He believes that there is a place for nuclear energy as we make the transition to a world without fossil fuels.

Peter Head Explains Natural Capital Peter Head defines natural capital as the whole ecosystem – the biocapacity of the planet and the natural systems that support our lifestyle. Pollution, carbon emissions, climate change, resource depletion and other actions with negative ecological impact combine to reduce natural capital.

Why Forests Matter Randy Hayes says forests matter: deforestation is a major contributor to global warming. He discusses the ways to save the world’s last four major forests, including the rainforest, from deforestation. He says we must develop alternatives to timber and wood products such as kenaf, hemp and paper substitutes.

What Nature Can Teach Us About Sustainable Design Janine Benyus says that industry can learn much from nature. Ecosystems like rainforests have inspired a number of industrial eco-parks. These co-locations of companies are highly energy efficient, low on waste and make good use of resources. This is green and sustainable design at its best.

Dealing with the Challenges of Global Warming Achim Steiner sets out the challenges of global warming and commends the IPCC and Nicholas Stern’s work in advancing understanding about climate change. How do we deal with global warming? We must stabilize greenhouse gas emissions within the next 10-15 years and reduce global emissions to avoid runaway climate change.

How Trees Benefit the Urban Environment Andy Lipkis explains that trees are basic survival tools in an era of increased climate change. Their root ecosystems purify rainwater and feed vital city water sources. We need these essential ecosystem services if cities are to be sustainable and cope with floods and droughts.

Sun Microsystems Bill Joy on Global Warming and Aviation Bill Joy, venture capitalist and co-founder of Sun Microsystems, says the human need to travel must be reconciled with lower carbon emissions to fight global warming. Aviation could be offset by green technologies such as eco-friendly cars. Fossil fuels must be replaced by sustainable fuel alternatives.
