1 . The climate we live in influences many areas of our lives. The quality of the food we eat，the water we drink，and our homes are all dependent upon our climate and weather. Some scientists have suggested that a warmer world would be a sicker world.
Climate researchers predict that the world climate will become warmer，with high temperatures in summer becoming more frequent and very cold winters more rare.
With winters becoming milder，there are likely to be up to 20,000 fewer cold-related deaths. However，there is a danger that bacteria would no longer die off seasonally during the cold period，which means that diseases may spread more widely.
More heat waves may increase the number of hot-weather related deaths by up to 2,800. Exposure to higher levels of UV light（ultraviolet light）could cause an extra 5，000 deaths a year from skin cancer and may cause an increase of up to 2,000 cases of eye diseases. Warmer summers may cause up to 10,000 extra cases of food poisoning each year.
Higher average global temperatures mean that diseases，or their carriers，may be able to move to areas that were previously too cold for them to survive. It is possible that a mild type of malaria（疟疾）will become established in some parts of the world and be a recurring threat for up to four months each year.
Globally，there are likely to be more floods，more droughts，and more storms，which will cause damage to our homes，food，and water supplies and then influence our health. The same could be said of an increase in flooding which would promote the spread of waterborne diseases，and droughts which would favor white flies and locusts.
Scientists have been studying the relationship between the outbreak of a severe disease in Africa and weather patterns. They believe that a rare climate pattern may come before outbreaks of the disease.
Climate change is likely to have unequal influences on the world population. Those living in poor and developing countries are going to be less able to adapt to the changes. Health influences are not likely to be limited to the human population -wildlife would also be severely affected.

2 . Plans to bring wild tigers back to their original home , their historical range(历史分布范围） in the IliBalkhash region, have been announced by Kazakhstan( 哈萨克斯坦 ) and an agreement with World Wide Fund for Nature (WWF) to conduct a tiger reintroduction program has been signed . “It will not only bring wild tigers back to their original home, but also protect the unique ecosystem of the IliBalkhash region，” said Askar Myrzakhmetov, the Minister of Agriculture of the Republic of Kazakhstan.
If successful, Kazakhstan will be the first country in the world to bring wild tigers back to an entire region where they have died out for nearly half a century. Tiger reintroduction projects have only been achieved within national borders and in areas that are considered current tiger habitats . Kazakhstan's tiger reintroduction program is unique and it badly requires the restoration of a vast forest that is part of the wild tiger's historical range.
Since the beginning of the 20th century, wild tigers have lost over 90 per cent of their historical range. Wild tigers have completely disappeared from the region since the late 1940s, due to the loss of habitat. To prepare for the return of wild tigers, on 1st January 2018 Kazakhstan will set up a new nature reserve in the southwestern IliBalkhash, in order to restore the unique forest habitat. This will include the protection of existing wildlife, and reintroducing important prey ( 猎物 ), such as the endangered wild Bactrian deer（中亚红鹿).
Restoring tigers will also help protect Lake Balkhash and prevent it from repeating the fate of the Aral Sea, formerly the world's fourth largest lake and now 10 percent of its original size. “The hard work remains ahead of us. We have to spare no effort to make this region ready for tigers and involve all the relevant people to make this happen. That means dealing with illegal activities, having these people who govern parks be welltrained and equipped, increasing prey populations and involving local communities，” said Ekaterina Vorobyeva, Director of the WWF program.

3 . There was a time when a trip to the supermarket in the United States often ended with a seemingly simple question from the cashier, "Paper or plastic？"Well, which type of bag would you choose？
While both types of bags have some influence on the environment, it has long been supposed that paper bags are kinder. They are made from a renewable source, are broken down easily, burn without giving off thick smoke and can be recycled. However, the producing process behind paper bags uses more energy than that of plastic ones. How can this be true？
Studies show that paper bag production requires four times as much energy as plastic bag production.
And the amount of water used to make them is twenty times higher. Besides, the influence on forests is very serious. It takes about fourteen million trees to produce ten billion paper bags, which happen to be the number of bags used in the United States yearly. In terms of recycling, the idea that paper bags are more environment friendly than plastic ones can be quickly discarded. Research shows it requires about 98% less energy to recycle plastic than it does to recycle paper.
Even though paper bags might be more harmful than plastic ones, plastic still seems to be considered as the more harmful of the two by governments. In Ireland, for example, a tax has been introduced to discourage the use of plastic bags. People have to pay 22 cents for every plastic bag, and as a result, their use has dropped quickly.
There’s no doubt that it makes more sense to reuse these bags. However, we don’t seem to be doing that at present. That may be because they fall apart quickly. If so, cloth bags are a better choice, but still, their production also has a bad influence on the environment. So what to do? How should we answer the question of “Paper or plastic?” It seems that we first need to ask ourselves one more general question: “What can I do to help the environment?”

California condors are North America’s largest birds, with wind-length of up to 3 meters. In the 1980s, electrical lines and lead poisoning(铅中毒) nearly drove them to dying out. Now, electric shock training and medical treatment are helping to rescue these big birds.
In the late 1980s, the last few condors were taken from the wild to be bred(繁殖). Since 1992, there have been multiple reintroductions to the wild, and there are now more than 150 flying over California and nearby Arizona, Utah and Baja in Mexico.
Electrical lines have been killing them off. “As they go in to rest for the night, they just don’t see the power lines,” says Bruce Rideout of San Diego Zoo. Their wings can bridge the gap between lines, resulting in electrocution(电死) if they touch two lines at once.
So scientists have come up with a shocking idea. Tall poles, placed in large training areas, teach the birds to stay clear of electrical lines by giving them a painful but undeadly electric shock. Before the training was introduced, 66% of set-freed birds died of electrocution. This has now dropped to 18%.
Lead poisonous has proved more difficult to deal with. When condors eat dead bodies of other animals containing lead, they absorb large quantities of lead. This affects their nervous systems and ability to produce baby birds, and can lead to kidney(肾) failures and death. So condors with high levels of lead are sent to Los Angeles Zoo, where they are treated with calcium EDTA, a chemical that removes lead from the blood over several days. This work is starting to pay off. The annual death rate for adult condors has dropped from 38% in 2000 to 5.4% in 2011.
Rideout’s team thinks that the California condors’ average survival time in the wild is now just under eight years. “Although these measures are not effective forever, they are vital for now,” he says. “They are truly good birds that are worth every effort we put into recovering them. ”
