Strategy 1: Bring your own cup to Starbucks |
|
|
You'll get a 10-cent discount, and it's one less paper cup to end up in a dustbin. |
The store won't create more waste when they throw away a cup. |
|
Strategy 2: Turn off your computer |
|
|
When in standby mode, your PC is still using energy. |
Turning off a monitor for 40 hours a week may only save $ 5 a month, but it reduces CO2 by 750 pounds. |
|
Strategy 3: Reuse plastic bags |
|
|
Instead of throwing away 100 billion plastic bags a year, try and get a second, third, or tenth use out of them. Better yet, next time you shop, try a reusable bag. |
You're reducing pollution. The amount of oil it would take to make just 14 plastic bags would run your car for one mile. |
|
Strategy 4: Use recycled paper in the bathroom |
|
|
Most of the toilet paper we use is made from trees found in forests previously untouched by humans. |
If every household replaced one roll of toilet paper with a recycled one,424,000trees would still be standing. Look for eco paper towels too. |
|
Strategy 5: Buy energy-efficient appliances(电器) |
|
|
Replace the old fridge with an Energy Star appliance and you'll use 15 percent less energy. It might be a little expensive to buy, but you'll save money on your electricity bills and help the environment. |
If we all used one Energy Star appliance at home, it would be like planting 1.7 million acres of new trees. |
|
Strategy 6: Plant a tree |
|
|
Adding green to your garden is beautiful and earth-pleasing. |
Just one tree will help make cleaner air and save the environment from 5, 000 pounds of hot carbon dioxide each year. |

Imagine your body is like the house you live in．Every day, your family creates rubbish．The rubbish builds up until it is put out for the weekly garbage collection．
Now, say you put three bags of garbage out, but because one of the collectors was away sick, only two bags are collected．You take the leftover bag inside to be put out again next week．The following week you put on another three bags, plus the leftover bag from last week．But again, only two bags are collected．Imagine this cycle is repeated over the following weeks．
This is a simple description of what happens to your body when your kidneys （肾脏）don't work efficiently．Your body is not thoroughly emptied of waste products．Other areas of the body such as blood pressure and red blood cell production are affected and the insidious process that may lead to kidney failure begins．
It's not uncommon for people to lose up to 90% of their kidney function before developing any symptoms．There may be no warning signs. This makes early detection （诊查）difficult．
Kidney's main job is to remove toxins（毒素） and unwanted water from our blood．Every day our kidneys clean an average of 200 litres of blood．Kidney failure may be a gradual and silent process, going unnoticed because there is no obvious pain．
Research shows that more than 35% of the patients requiring dialysis（透析）do not see a kidney specialist before they have to do so．Some risk factors for kidney disease such as age and genetic make-up are out of our control; however, some changes in lifestyle may help prevent kidney damage．Two major risk factors for kidney disease, diabetes （糖尿病）and high blood pressure, have been on the rise over the last few decades．Both conditions are chiefly affected by being overweight and not getting enough exercises, which are the potential (潜在的) risk factors for the kidney disease．
