 Global warming: what are the consequences?

What are the consequences of global warming? These are some predictions.

A rise of only a degree or two in the temperature of the planet will cause floods in many parts of the world. This is because the melting of the ice caps will cause a big rise in sea level. We will lose a lot of important farmland, and people will have to leave some of the world's biggest cities. 

Some deserts are growing so fast that we can see and measure the changes. Some scientists believe this is because of human activity (mainly cutting down trees), but others think that it is an effect of global warming. Good agricultural land is being changed into desert.

Animals adapt to survive in the climate of the area where they live. If the climate change, it will become too hot for some animals and too cold for others. Insects like mosquitoes will move to new areas and take malaria with them. Some crops won't grow and many people will starve.

Some scientists believe that nature will absorb the effects of greenhouse gases. For example, carbon dioxide dissolves easily in sea water. Shellfish use it to produce their shells. One theory is the shellfish will be able to absorb the extra carbon dioxide in the atmosphere.

Plants also absorb carbon dioxide. We know that the rainforests use carbon dioxide to photosynthesize and produce oxygen. This is why the rainforests are so important. If we don't protect them, the level of carbon dioxide will increase.


a. If temperatures go up by a degree, ____________________.

b. If the polar ice caps melt, the level ______________________.

c. We will lose a lot of farmland if the level ______________________.

d. If mosquitoes move to new areas, they _____________________.

e. Many people will starve if __________________________.

f. If there is extra carbon dioxide in sea water, shellfish ________________________.

g. The level of carbon dioxide will increase unless ____________________.

Computers Since computers were first introduced to the public in the early 1980's, technology  has changed  a great deal. The first computers were  simple machines designed for basic tasks. They  did not have  much memory and they  weren't  very powerful. Early computers were often quite expensive and customers often  paid  thousands of dollars for machines which actually  did  very little.

Computers have become  powerful machines with very practical applications.

How the recycling symbol was created  Gary Anderson designed a symbol which we see everywhere nowadays I studied engineering at the University of Southern California at a time when there was a lot of emphasis in the United States on training young people to be engineers.

It was around that time that I saw a poster advertising a design competition being run by the Container Corporation of America. The idea was to create a symbol to represent recycled paper. One of my college requirements had been a graphic design course so I thhought I'd give it a go. It didn't take me long to come up with my design: only a day or two. 1.___. But I already had arrows and angles in my mind because on my course I'd done a present
