Issues of Our Time Discover the greatest ecological issues of our time, why you should care, and how you can help.

Oceans in Peril Immense swaths of the ocean's creatures and habitats are being threatened by rapid and non-discriminating forces, such as coral bleaching, ocean acidification and overfishing.

Mass Extinction Human beings are currently causing the greatest mass extinction of species since the extinction of the dinosaurs 65 million years ago at rates 1000 to 10,000 times faster than normal.

Climate Change The trend is clear: if we don't take steps to curb global warming pollution, the far-reaching consequences will become increasingly dire for many generations to come.

Pollution Pollution can take many forms: the air we breathe, the water we drink, the soil we use to grow our food, the lit-up skies and even the increasing noise we hear every day.

Waste Waste can contaminate virtually anything, including soil, air, surface and ground water, which can lead to serious problems for humans, other species and ecosystems.

Habitat Loss Habitat loss is among the greatest threats to species diversity and the natural world, occurring when natural land cover, or its aquatic equivalent, is destroyed, fragmented or degraded.

Overpopulation Human population is growing at a rate of approximately 78 million people per year with estimates reaching 9 billion by 2050 and up to 15 billion by 2100.

Intensive Farming Intensive farming is an agricultural intensification and mechanization system that aims to maximize yields from available land through various means.

Fossil Fuels Fossil fuels, including oil, coal and natural gas, are currently the world's primary energy source and account for more than two-thirds of U.S. electricity generation.

Nuclear Power Nuclear power uses sustained nuclear fission to generate heat and electricity, providing about 5.7% of the world's energy and 13% of the world's electricity.

Finite Earth Despite massive landscapes and endless blue, our planet is limited in its resources and capabilities to support its inhabitants.

Action Center Discover the solutions to our most pressing environmental issues.

Reforest the World Take action for the remaining rainforests, indigenous communities and millions of species, including ourselves.

End Plastic Pollution Ending plastic pollution is about avoiding plastic in the first place and if unable to, reusing or recycling the material.

Protect Wildlife Protecting wildlife has never been so essential in the history of humanity and for the sake of humanity.

Reduce Waste Reducing, reusing and recycling makes economical and environmental sense by saving land and money communities must otherwise use to dispose of waste in landfills.

Conserve the Oceans Discover 16 things you can do to help conserve the oceans and how living blue is living healthy!

Avert Climate Change Unless we act now, our children will inherit a hotter world, dirtier air and water, more severe droughts, floods, wildfires, extreme weather, a massive loss of biodiversity, ecosystems in peril and a destabilized climate.

Preserve Habitats Learn how to save farmland, conserve habitats, and reduce urban sprawl.

Reduce Pollution A polluted environment is a polluted society - one we created and one only we can renew.

Sustainability Sustainability is based on the principle that everything we need for our survival, well-being and prosperity depends either directly or indirectly on the natural environment.

Guide to Green Living Green living is about discovering the many creative, compassionate, economical, smart and sustainable actions you can blend into your everyday life or add to your list of goals in order to help sustain the systems that sustain us.

Renewable Energy With unlimited resources and near zero pollution, renewable resources, such as solar and wind power, create electricity by harnessing the power of natural cycles and systems turning the omnipresent energy around us into usable, sustainable forms.

Transition Towns Transition towns address the issues of peak oil, climate change and economic instability by creating a strong, connected, self-sufficient community.

Sustainable Agriculture Learn how we can feed the world while protecting people and the planet.
