You're in a bit of a dilemma standing in front of the produce section of your local supermarket.
In one hand, you're holding a conventionally grown Granny Smith apple. In your other hand, you
have one that's been organically grown. Both apples are firm, shiny and green. Both provide vitamins
and fiber, and both are free of fat, sodium and cholesterol.
   The conventionally grown apple costs less and is a proven family favorite. But the organic apple
has a label that says "USDA Organic". Does that mean it's better? Safer? More nutritious? Become
a better informed consumer for your next trip to the supermarket.  Several differences between
organic and non-organic foods exist. The word "organic" refers to the way farmers grow and process
agricultural products, such as fruits, vegetables, grains, dairy products and meat. Organic farming
practices are designed to encourage soil and water conservation and reduce pollution. Farmers who
grow organic produce and meat don't use conventional methods to fertilize, control weeds or prevent
livestock disease.
   Here are other differences between conventional farming and organic farming:

* Organic or not? Check the label
    The U.S. Department of Agriculture (USDA) has established an organic certification program
that requires all organic foods to meet strict government standards. These standards regulate how
such foods are grown, handled and processed. Any farmer or food manufacturer who labels and
sells a product as organic must be USDA certified as meeting these standards. Only producers who
sell less than $5,000 a year in organic foods are exempt(免除) from this certification.
    If a food bears a USDA Organic label, it means it's produced and processed according to the
USDA standards. The seal is voluntary, but many organic producers use it.

     People are looking for ways to reduce their carbon footprint. Purchasing property that is
environmentally responsible is a good investment for those who are concerned about their own
health and the well-being of the earth. Based on this trend, entire districts, known as eco-communities,
are being designed with a green focus in mind. Dockside Green in Victoria, British Columbia is
one of them.
    If everything goes according to plan, Dockside Green will be a self sufficient community along
the harbour front of British Columbia's capital city. The community will be home to 2500 people
and will consist of residential, office, and retail space. Builders of Dockside Green have the
environment in mind with every choice they make. They ensure proper ventilation(通風(fēng)), and
guarantee residents 100% fresh indoor air. Building materials, such as paints and wood, are natural
and non-poisonous. Eco-conscious builders use bamboo wherever possible because it grows fast
and does not require pesticides(殺蟲劑) to grow.
    Energy efficiency is one of the top concerns in eco-communities, such as Dockside Green. Not
only do energy efficient appliances and light fixtures(照明設(shè)備) reduce the environmental impact
of heating and hot water, they also save residents and business owners money. Dockside Green
claims that home owners will use 55% less energy than average residents in Canada. Residents will
have individual water metres as studies show that people use around 20% less energy when they are
billed for exactly what they use. In addition, water is treated at Dockside Green and reused on site
for flushing(沖洗) toilets.
    Planners of eco-communities such as Dockside Green must take the future into account. Dockside
Green plans on reusing 90% of its construction waste. They also plan to continue using local suppliers
for all of their transport and maintenance needs. This is a great way to reduce emissions(排放).
Dockside residents will be encouraged to make use of a mini transportation system and buy into the
community's car share program. Finally, plans are in the works for a high-tech heating system that
will use renewable energy instead of fossil fuels (化石燃料).
    Dockside residents will benefit from excellent local services with high quality healthcare, shopping
and education at the heart of the community, along with excellent recreation facilities and plentiful
green open spaces. The Eco-Community will favour the use of locally-sourced goods and services;
they will be desirable places to live, promoting a tangible(看得見的) sense of civic pride, responsibility
and, as the name suggests, community.

          Anger and bitterness may affect your health. According to a research,forgiveness may help
you keep healthy,both physically and mentally.
     Forgiveness-giving up anger toward another- can greatly reduce your body's anger and
stress responses,which affect your mental and physical health. Research conducted by the University
of Michigan's institute for Social Research has showed that people who for-give themselves and
others experience reduced feelings of restlessness,nervousness and hopelessness. Other researches
have found forgiveness can also lower blood pressure and heart rates.
     "Stress worsens pain,tightens muscles and influences the smooth running of the immune(免疫)
system." says Fred Luskin,director of the Forgiveness Project at Stanford University." People think
they have unlimited storage of anger that will never do harm to their health,but they are quite wrong."
     And good news:You don't have to be Gandhi to forgive others or ask for forgiveness." Forgiveness
is a teachable skill,which you can learn just like you learn to play the piano." says Luskin.
     Remember these tips when learning to forgive:
     Commit yourself. Do whatever you have to do to feel better. Forgiveness is for you not______.
     Grasp the truth. Recognize that your primary bitterness comes from the hurt feelings and physical
upset you suffer now,not what offended or hurt you 2 minutes or 10 years ago.
     Meet positive goals. Instead of mentally replaying your hurt,seek a new and positive future.
     Live well. remember that a life well lived is the most important. Stop focusing on wounded
feelings-that gives the person who caused your pain power over you. Instead,look for love,beauty
and kindness around you.

    "The world's oceans are slowly getting more acidic．"say scientists．The researchers from California
report that the change is taking place in response to higher levels of carbon dioxide in the atmosphere.
    The lowering of the waters'pH value is not great at the moment but could cause a serious threat to
current ocean life if it continues, they warn. Ken Caldeira and Michael Wickett, from the Lawrence
Livermore National Laboratory, report their concerns in the journal Nature.
Increasing use of oil fuels means more carbon dioxide is going into the air, and most of it will eventually be
absorbed by seawater. Once in the water, it reacts to form carbonic acid. Scientists believe that the
oceans have already become slightly more acidic over the last century.
    These researchers have tried to predict what will happen in the future by combining what we know
about the history of the oceans with computer models of climate change．"This level of acidity will get
much more extreme in the future if we continue releasing COZ into the atmosphere," said Dr Caldeira.
"And we predict the amount of future acidity will exceed(超過)anything we have seen over the last
several hundred million years, let alone perhaps after rare disastrous events such as asteroid(小1j-%+)
impacts．"
    However, it is not absolutely clear what that means for ocean life．Most organisms live near the
surface, where the greatest pH change would be expected to occur, but deep-ocean life forms may
be more sensitive to pH changes．Coral reefs and other organisms whose shells contain calcium carbonate(小行星) may be particularly affected if the water's acidity levels keep going up, the team predict. They
could find it much more difficult to build these structures in water with a lower pH.
    In recent years some people have suggested storing carbon dioxide from power stations in the deep
ocean as a way of dealing with global warming．But Dr Caldeira said that such a strategy should now be
re-considered. "Previously, most experts had looked at ocean absorption of carbon dioxide as a good
thing一because in releasing CO2 into the atmosphere we warm the planet, and when CO2, is absorbed
by the ocean, it reduces the amount of greenhouse warming."
