The earth is not the only planet that is experiencing climate change. 答案:26-30 DCBBD B Japanese researchers are genetically changing mosquitoes so that they become carriers of a vaccine that could vaccinate millions for free. The researchers have already genetically changed a mosquito species so that its saliva contains a protein that acts as a vaccine against leishmaniasis, a deadly disease that leads to terrible skin problems. The team confirmed that mice bitten by the genetically-engineered mosquito developed an antibody to the disease, meaning they had built up immunity . “You would be vaccinated without even noticing. You wouldn’t need any drug and you wouldn’t need to show up at a fixed place for mass vaccinations, said Shigeto Yoshida, the associate professor who has led the research. “Repeated bites would only strengthen the immunity. Similarly the mosquitoes could be used to help treat malaria , perhaps a decade from now, said the malaria expert. Nearly one million people die each year from malaria - most of them children - mainly in Africa and Asia, according to the World Health Organization. Now a problem is that no effective vaccine exists. “There is a treatment that works, but it is beyond the reach of people who need to worry about food for tomorrow, Yoshida said. However, Yoshida expects that the genetically-engineered mosquito will finally help wipe out the deadly disease in the developing world. “Technically speaking, I believe it’s a matter of 10 years or so, but it’s not clear whether society would accept it, he said. Another problem is that the genetically-engineered mosquito may still pick up and spread the infected blood of a person who has already caught malaria. Yoshida’s team is hoping it can solve this problem by developing a mosquito species that kills the malaria virus inside its own body.

Based on new analysis, we are rapidly approaching major climate change and the effects on society and the environment could be quite severe. Geographers predict that within the next eighty years, current world climate zones could shift and some could completely disappear. Polar regions will get colder while tropical regions will get even hotter, forcing animals to migrate  (迁徙) north.
Climate changes like these could lead to the spread of diseases. Tropical storms and hurricanes will not only increase but may also become more intense. If the changes come too quickly, animal and plant species may not be able to adapt fast enough and could disappear.
According to Science Daily, a new study predicts that by the year 2100, many of today’s familiar climates will be replaced by climates unknown in today’s world. It is urgent that we reduce the risks of these far-reaching consequences for the whole world. The planet itself has been showing signs of change. In 2004, a serious tsunami created by a major earthquake killed thousands in Sumatra and in 2008, thousands died in China because of another severe earthquake. Egypt was hit in 2009 with a major earthquake and Haiti was devastated in 2010 by yet another massive earthquake.
Within just the last few months, new reports from around the world have been coming in and most agree that our climate situation is much worse than previously thought. At this point, it doesn’t matter what is causing it, but rather, what can be done about it. What’s more, our world is getting more and more unstable every year. There is war and threat of war everywhere. Natural disasters are becoming more frequent and serious.
However, other planets are experiencing global warming as well as our own and some scientists believe there may be some connection between this. No one knows anything for sure at this point because there is simply not enough data
