Part 1
“This morning, it took me 40 minutes to go downtown. More roadworks on the A10!”
“Oh really lt took me over an hour. There was an accident on the M11.”
How often have you heard these conversations How often do we get stuck in traffic jams How often do we arrive at work or school, stressed out, tired and angry For many people, the answer is every day. But personal anger and stress are nothing compared to the real costs socially. Here are some figures about Britain:
In the last 20 years, the number of cars on the roads has gone up by 25%. There are now 32 million cars.
Over the last decade, an average of 2,500 people have died every year in vehicle accidents.
Traffic is one of the major causes of global warming and climate change, as car engines produce various types of greenhouse gases.
Almost 30,000 deaths per year are caused by air pollution.
Some types of cancer are related to traffic pollution.
Part 2
We know that cars are bad for us. But we all make excuses: “The buses are terrible”; “The trains are always late”; “ I haven’t got time to walk”, I’m talking about myself, too. To be frank, I’m addicted to my car. When I asked a friend working for a green-living organisation for advice about how to give up, she told me five things:
Use your legs. In 2014, over 55% of car journeys were under eight kilometres. Instead of taking short car journeys, we could easily walk or cycle. Leg power can save your money, keep you fit and help you live longer. Regular exercise also cuts the risk of heart disease by 50%!
Use public transport. Up to 90 people can travel in one bus, while the same number will need at least 18 cars. Sometimes it can take a little bit longer, but so what You can relax, read a book, talk to someone - who knows
Think before you go. Do you really have to go to that shopping centre on the other side of town What about the shops around the corner Before you get into your car, think about whether you really need to make that journey.
Share cars. lf you really have to use a car, share journeys with someone else. It is much cheaper and kinder to the environment.
Take action! We often think there is nothing we can do about the noise, pollution and danger of traffic, There is. If your street is full of heavy traffic, talk to your neighbours about it, Write to the papers, Go to the city government. Ask for a speed limit. Do whichever of these things that suit you. Don’t just sit around and complain!
All quite simple, isn’t it Five easy ways to improve our environment. Well, I’m sorry I have to finish this article, but I’ve got to pick up my daughter from school at 4 pm. Then l’ve got to drive to the supermarket to do the shopping. After that, l have to take my son to a party. The traffic is going to be horrible, but what can l do
