A study, by scientists at the World Health Organization (WHO) determined that 154,000 people die every year from the effects of global warming. These numbers could almost double by 2020.
"We estimate that climate change may already be causing in the region of 154,000 deaths...a year," Professor Andrew Haines of the London School of Hygiene and Tropical Medicine told a climate change conference in . Haines said the study suggested climate change could "bring some health benefits, such as lower cold-related mortality and greater crop yields in temperate zones, but these will be greatly outweighed by increased rates of other diseases." Haines mentioned that small shifts in temperatures, for instance, could extend the range of mosquitoes that spread malaria. Water supplies could be contaminated by floods, for instance, which could also wash away crops.
II. Establish Credibility
I have been interested with science, life and nature since I was in primary school. Since then, I joined many campaigns and make my own research through reading and experimenting myself based on science subject that I learned in school. Till now I am still committing it in my daily life, just to make sure that I can contribute to curb the global warming.
III. Thesis Statement
Today I would like to share what I’ve learned about global warming and its causes. First I’d like to enlighten the problem of global warming. Second describe how the cause of global warming. Last but not least discuss what we can do as an individual to do our part to help save the planet from global warming.
Global warming is affecting many parts of the world. Global warming makes the sea rise, and when the sea rises, the water covers many low land islands. This is a big problem for many of the plants, animals, and people on islands. The water covers the plants and causes some of them to die. When they die, the animals lose a source of food, along with their habitat. Although animals have a better ability to adapt to what happens than plants do, they may die also. When the plants and animals die, people lose two sources of food, plant food and animal food. They may also lose their homes. As a result, they would also have to leave the area or die. This would be called a break in the food chain, or a chain reaction, one thing happening that leads to another and so on.
Many things cause global warming. One thing that causes global warming is electrical pollution. Electricity causes pollution in many ways, some worse than others. In most cases, fossil fuels are burned to create electricity. Fossil fuels are made of dead plants and animals. Some examples of fossil fuels are oil and petroleum. Many pollutants (chemicals that pollute the air, water, and land) are sent into the air when fossil fuels are burned. Some of these chemicals are called greenhouse gasses.
We use these sources of energy much more than the sources that give off less pollution. Petroleum, one of the sources of energy, is used a lot. It is used for transportation, making electricity, and making many other things. Although this source of energy gives off a lot of pollution, it is used for 38% of the ’ energy.
Some other examples of using energy and polluting the air are:
Turning on a lightWatching T.V.Listening to a stereoWashing or drying clothesUsing a hair dryerRiding in a carHeating a meal in the microwaveUsing an air conditionerPlaying a video gameUsing a dish washerWhen you do these things, you are causing more greenhouse gasses to be sent into the air. Greenhouse gasses are sent into the air because creating the electricity you use to do these things causes pollution. If you think of how many times a day you do these things, it’s a lot. You even have to add in how many other people do these things! That turns out to be a lot of pollutants going into the air a day because of people like us using electricity. The least amount of electricity you use, the better.
When we throw our garbage away, the garbage goes to landfills. Landfills are those big hills that you go by on an expressway that stink. They are full of garbage. The garbage is then sometimes burned. This sends an enormous amount of greenhouse gasses into the air and makes global warming worse.
Another thing that makes global warming worse is when people cut down trees. Trees and other plants collect carbon dioxide (CO2), which is a greenhouse gas.
conclusion:global warming is a human oriented problem which can be controled by following some measures.
