How often do you travel by plane？

　　How much electricity do you use? These days everyone is worried about the size of their carbon footprint．In order to reduce global warming we need to make our carbon footprints smaller．But how much CO₂ are we responsible for?

　　A new book by Mike Berners Lee(a leading expert in carbon footprint)might be able to help．How Bad are Bananas? The Carbon Footprint of Everything looks at the different things we do and buy, and calculates the amount of CO₂ all of the following created：the ingredients, the electricity used in the brewery, the equipment, the travel and commuting of the beer, and the packaging．It's amazing how many different things need to be included in each calculation．And it's frightening how much carbon dioxide everything produces．

　　But all of this can help us decide which beer to drink．From Berners-Lee's calculations, it's clear that a pint(568ml)of locally-brewed beer has a smaller carbon footprint than a bottle of imported beer．This is because the imported beer has been transported from far away, and it uses more packaging．The local beer only produces 300g of CO₂, but the imported beer produces 900g! So, one pint of local beer is better for the environment than three cans of cheap foreign lager from the supermarket．

　　Berners-Lee has even calculated the carbon footprint of cycling to work．Nothing is more environmentally-friendly than riding a bike, surely? Well, it depends on what you've had to eat before．To ride a bike we need energy and for energy we need food．So if we eat a banana and then ride a kilometer and a half, our footprint is 65g of CO₂．However, if we eat bacon before the bike ride, it's 200g．In fact, bananas are good in general because they don't need packaging, they can be transported by boat and they grow in natural sunlight．

　　So, does this mean that cycling is bad for the environment? Absolutely not, for a start, if you cycle, you don't use your car, and the fewer cars on the road, the fewer traffic jams．And cars in traffic jams produce three times more CO₂ than cars traveling at speed．Cycling also makes you healthy and less likely to go to a hospital．And hospitals have very big carbon footprints!

　　So maybe it's time for us all to start making some changes．Pass me a banana and a pint of local beer, please．

　　“Help!Help!Help!” a resident screamed over the phone, “I am being eaten alive by mosquitoes!”

　　Recent rainfalls have produced an early hit of blood-seeking mosquitoes．Once flooded, eggs laid during the drought along water banks hatch(孵化)quickly, flying off to seek hosts such as people, birds, and other animals．

　　The flood mosquitoes are big and aggressive．They chase you down, drill into your skin and take your blood, causing pain and itchiness．“I have lost a pint of blood to those suckers,” a Spring Hill resident claimed．“Mosquitoes are killing my kids,” a Ridge Manor woman shouted．

　　Residents are urged to protect themselves when going out, especially during the hours of dusk and dawn．Long-sleeve shirts, long pants, socks and hats will help keep mosquitoes at bay．

　　Mosquito Control has already received hundreds of service requests this month．When calling in, residents need to provide their name, address, phone number and nature of the problem．Technicians will respond by investigating the problem and making proper treatment and notification to resident．

　　Mosquitoes grow in almost any kind or amount of water．Controlling mosquito larvae(幼虫)is vital to mosquito control．Confined in their water habitat, larvae are treated and eliminated before they mature and “take to wing．” Field technicians check their areas searching for mosquitoes breeding in lakes, ponds, drainage ditches and they treat the water with a host of larvicides(杀幼虫剂)．

　　It is important to understand that mosquito control is much more than sending a spray truck(airplane or helicopter in other counties)to kill adult mosquitoes．Night-time spraying is actually the last defense after all the above procedures have been done, but there are still mosquitoes present in the area．
