In the 1960s Professor Bolin predicted (预测) that the “greenhouse effect”, caused by an increase in the amount of carbon dioxide (CO2) in the atmosphere, would lead to important changes in the Earth’s climate. At the time his prediction were regarded as science fiction. But it is now gradually agreed that the amount of carbon dioxide in the atmosphere will double from 0.03% to 0.06% in the next 50 years and that temperatures worldwide will rise by 2°C.

Although a temperature rise of 2° may not seem significant, the local effects may be much greater: in polar regions a rise of 10° by 2025 is expected and in Northern Europe a rise of 4°. Indeed the first effects were expected to be felt before the end of the 20th century.

But how does the “greenhouse effect” operate and why should such a tiny proportion (比例) of CO2 have such a harmful effect? When living creatures breathe out or when things are burned, CO2 enters the atmosphere. Until recently all of this was absorbed by plants, which converted (转化) it back into oxygen.

However, the balance of nature has been disturbed. In power stations, in factories and in our cars, we are burning more and more fossil fuels (coal, oil and natural gas) and this produces huge quantities of CO2—18 billion tons of it enter the atmosphere every year. Added to this, the destruction of forests means that less CO2 can be converted into oxygen by plants. So, the amount of CO2 in the atmosphere is increasing every year.

Several dollars equal nothing for some people, but make a difference for others. Steve has just lost his wife to cancer and everything they had is gone due to the treatment. He now lives in the shelter for the homeless. So we know each other.

Just like other homeless people, he didn’t think he needed anything. But once he mentioned to me he needed eye glasses. His voice hesitated a bit, he looked down, and it appeared like he thought such a request was just a dream. Too much to hope for? It was as if his wish were known by me only.

I submitted an application for him to a program that is supposed to provide a free eye examination and glasses. Three months later, I phoned to ask what was up with the appointment but they told me there was a cash flow problem until late summer.

Steve showed disappointment, thanked me and started to walk away. I said, “Hold on, I will figure out a way to get you an eye examination and glasses.” His face lit up a tiny bit. He had seen some of the things I have done for other people in our shelter and to me it looked like he might have a line of hope.

I took a picture of him and posted his picture and his story in the Twitter. In about 4 days, eight people from around the world donated $25 each and one person donated $40 and I made up the rest to get him an eye exam and glasses.

Steve picked up his glasses on Wednesday: May 11th, 2011. Today Steve has returned to a previous job he had in a nearby car wash. Because he now has glasses he will be able to see what he is doing while cleaning the vehicles. He is starting a second job at a pet center next week!
