SOIL EROSION & DESERTIFICATION

Unsustainable industrial agriculture practices have resulted in soil erosion and degradation that leads to less arable land, clogged and polluted waterways, increased flooding and desertification. According to the World Wildlife Fund, half of the earth’s topsoil has been lost in the last 150 years.

What You Can Do: Support sustainable agriculture that puts people and the planet above profit. Show your support for sustainable agriculture by signing this Greenpeace campaign for “a global food system that feeds people, enables the small farmer to thrive, protects the soil, water and climate, and promotes biodiversity. This is a system free from genetic engineering and chemical-intensive agriculture.” On a smaller scale, you can make a difference in your backyard by switching to non-toxic green pesticides, herbicides and fertilizers, corn gluten organic fertilizer.

=====================================================================================

WATER SCARCITY

As the population increases and climate change causes more droughts, water scarcity is becoming more of an issue. Only three percent of the world’s water is fresh water and 1.1 billion people lack access to clean, safe drinking water. As the current drought in California dramatically shows, access to water is not just an issue for developing countries but the United States as well.

What You Can Do: Just as energy efficiency is considered an important solution to the issues of climate change and pollution, water efficiency can help us deal with water scarcity. Some ideas to be more water efficient include installing an ENERGY STAR-certified washer, using low-flow faucets, plugging up leaks, irrigating the lawn in the morning or evening when the cooler air causes less evaporation, taking shorter showers and not running sink water when brushing your teeth. Also, consider using non-toxic cleaning products and eco-friendly pesticides and herbicides that won’t contaminate groundwater.

=====================================================================================

POLLUTION

Air pollution and climate change are closely linked, as the same greenhouse gas emissions that are warming the planet are also creating smoggy conditions in major cities that endanger public health. If you’ve seen horrifying images of pollution-choked Chinese cities and think the smog is isolated to Beijing or Shanghai, think again.

Water and soil pollution might not get the media attention that air pollution does, but they are still important public health concerns. According to the Natural Resources Defense Council, dirty water is the world’s biggest health risk.

Soil contamination is a major issue across the world. In China, nearly 20 percent of arable land has been contaminated by toxic heavy metals. Soil pollution threatens food security and poses health risks to the local population. The use of pesticides and fertilizers are also major factors in soil pollution

What You Can Do: Many of the solutions to air pollution are similar to those for climate change, though it’s important to either make a concerted effort to drive less, or switch to a lower-emissions vehicle. Switching over to green energy is also important, as that will cut back on fossil fuel emissions.

=====================================================================================

LOSS OF BIODIVERSITY

Increasing human encroachment on wildlife habitats is causing a rapid loss of biodiversity that threatens food security, population health and world stability. Climate change is also a major contributor to biodiversity loss, as some species aren’t able to adapt to changing temperatures. According to the World Wildlife Fund’s Living Planet Index, biodiversity has declined 27 percent in the last 35 years.

What You Can Do: As consumers we can all help protect biodiversity by purchasing products that don’t harm the environment. Next time you are at the grocery store, check to see if food packaging contains any of the eco-label. Also, reusing, recycling and composting are easy ways to protect biodiversity.

=====================================================================================

DEFORESTATION

Forest are important to mitigating climate change because they serve as “carbon sinks,” meaning that they absorb CO2 that would otherwise escape into the atmosphere and worsen global warming. It is estimated that 15 percent of total greenhouse gas emissions come from deforestation. Cutting down trees also threatens animals and humans who rely on healthy forests to sustain themselves, and the loss of tropical rainforests is particularly concerning because around 80 percent of the world’s species reside in these areas. About 17 percent of the Amazon rainforest has been cut down in the past 50 years to make way for cattle ranching. That’s a double whammy for the climate because cattle flatulence is a major source of methane gas, which contributes more to short term climate change than carbon emissions.

What You Can Do: You can support organizations, stop using paper towels and use washable cloths instead, use cloth shopping bags (instead of paper), and look at labels to make sure you only use certified wood and paper products. You can also boycott products made by palm oil companies that contribute to deforestation in Indonesia and Malaysia.

=====================================================================================

CLIMATE CHANGE

While 97 percent of climate scientists agree that climate change is occurring and greenhouse gas emissions are the main cause, political will has not been strong enough so far to initiate a massive policy shift away from fossil fuels and toward sustainable forms of energy. Perhaps more extreme weather events such as droughts, wildfires, heat waves and flooding will convince the public to put more pressure on policymakers to act urgently to curb carbon emissions and address this issue before it’s too late.

What You Can Do: Your home and transportation could be major sources of greenhouse gas emissions. A certified home energy audit can help make your home more energy efficient. If you commute via biking, walking or public transportation you are doing your part to fight global warming, but if you must own a motor vehicle, consider trading in your gas guzzler for a fuel efficient hybrid or better yet—go electric. When you fly, make sure to reduce your carbon footprint from air miles traveled with carbon offsets.
