Biomass is one of the most common renewable energy resources which produced from the carbonaceous waste of our and natural activities. It is a result from many sources, such as wood, agricultural crops, unprocessed material from the forest, parts of household waste and timber.
It has many advantages; first significant advantage is that it can be used to generate electricity with the same tools or power plants that are now burning fossil fuels. Secondly, Biomass is an important source of energy and the most important fuel worldwide after coal, natural gas and oil. This power is being used for: Power generation, Cooking, cars and other mechanical application. In these days, biomass has been used less than before. In the developed countries like India, this energy is an important source for applications like combined heat and power generation.
In the end, biological material such as trees, grasses, agricultural crops or other can be used as a solid fuel that generates electric power, heat, chemicals, or fuels. Today, there are many resources to produce energy but wood is the main energy resource which is good for economy.

Critical thinking
Critical thinking needs a lot of concentration, we should always be aware about what’s going on around us. We must look for solution of new things happen to our daily live and search the advantages if they are good and specific their disadvantages by giving an opinion or proofing. Critical thinking is best way to understand things as the ability of thinkers to take the responsibility of their own thinking. So they must build up their standards for analyzing and assessing their own thinking and regularly use those principles to improve its quality. In our countries we have many critical thinkers like Sheikh Mohammed Bin Rashid Al Maktoum, Ruler of Dubai (United Arab Emirates). A man who believe that if we work so hard we can get what’s mine and reach the top .
Abu Dhabi (Masdar)
The time has come for solar power, the United Arab Emirates will make a $350 million solar power plant in Abu Dhabi, which is the first city that will going to use this energy in the Arab’s world
The UAE want to use alternative energy which is solar power that generates about 500 megawatt plant, likely to begin in 2009. there are many reasons why This energy is good for our environment , the first reasons is that it has no carbon emission because it converts solar energy directly into electricity, on the other hand, our country want to reduces the using of hydrocarbon power which is causing the global warming. Second advantage is that it generates lots of electricity from sunlight and it will be really cheap in the long-long term. Other significant advantage is that creates no pollution, this helping to reduce the damage of dependency on fossil fuel power stations. The final positive Point is that it creates many jobs which reducing unemployment people
In the end, our country moves to the next level of cleaning the environment and reducing the global warming by building alternative power for pure future.

Carbon Footprint
A Carbon footprint is our personal behaviour which effects global warming through the amount of our activities and CO2 production which is a very serious gas that damaging our environment.
There are many causes that lead us to this serious problem. First, we should take a look to our houses. Recent studies show that boiler and air conditioner are the most major causes of carbon emissions from our houses. Lighting is the next one, which produce a high carbon emission. Also papers and food also produce a certain amount of CO2.The final problem is that people don’t care about their planet because most of them don’t believe the truth about carbon footprint or global warming.
Turning to the solutions, we can use our effort to reduce this serious issue. At home, we should reduce the use of air conditioner that can help to reduce the CO2 emissions and bills. Also, televisions and other device should be turned off when we are not using them. Then, we should recycle our papers and other wasting goods to its recycling center.The final solution is that we have to travel by bus or train instead of cars or airplane because they emitted a great amount of CO2.
In the end, I have learned that carbon footprint is a very powerful shock of our results behaviour on global warming. We should work together hand by hand to stop this problem and make our planet more suitable for living for the next generation.

My view about the movie
This is a very important movie to watch because it tells many facts that we are not very interested in. This movie talked about many evidences that accrued due to global worming. We should take actions to prevent this massive disaster and we have the chance to change our routine to be more careful for our environment and live happy and healthy life
Summary about An Inconvenient Truth Movie
The former U.S. Vice President Al Gore did this movie of An Inconvenient Truth which told that we are causing the global warming, and the effects are overwhelming. All scientists agree that global warming is true. There are many evidences that global warming is here .There are many changes in our planet such as glaciers are melting, plants and animals are being reduced, and storms and hurricanes are being increased. In the last 30 years, hurricanes were almost doubled. Another fact is that Malaria has stretch to higher altitudes in places like the Colombian Andes, 7,000 feet above sea level. In Greenland, glaciers cause many ice flowing which has doubled over the past 15 years .About 279 kinds of plants and animals moved nearer to the poles due to global warming. Many people die due to global warming, about 300,000 people passed away in the last 25 year. In Greenland and Antarctica, shelf ices are being moved because sea levels rise by more than 20 feet. There are many droughts and wildfires because the sun is heating up .In the year of 2050; scientists predict that ices would be melting in the Arctic Ocean and many parts of the world would disappear.

HAppy Earth Day 2008
Earth Day, a day dedicated to the environmental health of our planet. Earth Day is observed in the United States, Canada, and many other countries around the world with programs designed to educate people about Earth’s environment and threats to the environment. Activities intended to improve the environment also take place. Earth Day is most often celebrated on April 22, but some people observe it on March 21, the first day of spring. Activities surrounding Earth Day may continue for weeks or months.
II Origin of Earth Day
Print this section
Earth Day was first observed on April 22, 1970. The idea for a nationwide demonstration in support of Earth’s environment came from Senator Gaylord Nelson of Wisconsin. Nelson is considered the founder of Earth Day. On the first Earth Day in 1970 as many as 20 million Americans in schools and communities across the country participated in rallies and demonstrations on behalf of Earth. In New York City, Mayor John Lindsay closed Fifth Avenue to automobile traffic, and thousands of people attended a fair on ecology in Central Park.
III Activities on Earth Day
Print this section
By 1990 Earth Day had become an international event, with more than 200 million people in 141 countries participating. Environmental groups use Earth Day as an occasion to draw attention to current local and global environmental problems and to discuss commonsense solutions. At fairs, festivals, and talks, people learn about air pollution, water pollution, and soil pollution; the destruction of habitats (see Ecosystem); the devastation of hundreds of thousands of plant and animal species (see Endangered Species); the depletion of nonrenewable resources (see Conservation); and global warming. They explore exhibits on such topics as conserving energy, recycling, renewing natural habitats, leading healthier lives, making their backyards friendly to wildlife, and protecting endangered species. Volunteers gather to pick up litter; clean up streams, reservoirs, and other water supplies; restore parks; plant trees; and participate in other environmental activities.
An organization called Earth Day Network coordinates Earth Day activities around the world. The organization estimated that 1,000 groups and 500 million people were participating in Earth Day observances by the early 2000s.
