Transcript of BIOFUEL

THE BENEFITS OF BIOFUEL TO HUMAN

Biofuels have a benefit on humans because instead of cutting trees we can increase the food production to create biofuel.For transportation and less deforestation.







WHY IS BIOFUEL BAD
Biofuels sound great, but there is a problem. Most are derived from crops, and to grow them takes a lot of land and intensive agricultural practices. They are grown as monoculture (single fields full of just one crop) and we have to use pesticides, herbicides and artificial fertilisers to ensure a good yield. This intensive farming has an impact on biodiversity. The clearing of rain-forests for biofuel crops is also a major issue.
HOW IS BIOFUEL USED
There are two major types of biofuels, ethanol and biodiesel. Some cars and trucks can use 85% ethanol and other can only use 10% ethanol with the gasoline. Aircrafts now are also starting to use biofuels to power the engine. Mainly because biofuels rely on crops, food and livestock feed to be produced.

HUMANS FALSE OPINION
THE ISSUE


What most people don't know, and what I argue, is that biofuel is bad. Not only for the environment, but for the economy as well. To satisfy human's need for oil, more and more farmland is being converted to plant soybeans, corn, and sugarcane, all vegetable matter that is commonly used for ethanol. These crops are going to refineries to make oil for cars, causing the food shortage that people were going crazy about, about a year ago. Rain forests are also being chopped down at a faster rate to offer more farmland to making biofuel.

THE BENEFITS OF BIOFUEL
WHAT IS BIOFUEL
A biofuel is a fuel that contains energy from carbon dioxide. These fuels are produced from living organisms. These fuels are made of living organisms such as foods and livestock feed. Biofuel can be converted in three different ways such as thermal, chemical, and biochemical conversions. These conversions can result in fuel in solid, liquid, or gas forms.


Biofuels were our first transportation fuels

The first cars ever built were made to function on biofuels, rather than fossil fuels
Henry Ford designed his original 1908 Model to run on ethanol
Meeting global biofuel targets could force hundreds of millions more people into hunger.
Biofuels will never be a good solution. The energy problems we face are so large and complex that multiple strategies will be needed. Biofuels, teamed up with efficiency measures and conservation, can be a part of an overall solution. However, in the short time that biofuel crops have been planted aggressively, we have seen a rise in grain prices globally causing hunger and starvation among the world's poor, and increased prices for grain for everyone.
