Deforestation
Deforestation is cutting or burning trees. Most deforestation happens because people need lands for farming. In poor countries, most people must plant vegetables. Farming is the main resource for living.
Economy is the main reason of deforestation. Poorer countries use their only resources for money. People use land for farming to make money because of poverty. Governments cut trees because of their debts and development of industries.
But these solutions can cause even worse problems. Trees are made of about 50% carbon, so when trees are burnt, carbon is released into the atmosphere. Cutting them down reduces the amount of rain, raising temperatures. The sun heats the land and dry it out. Also it is very harmful for the animals and plants that live in the rainforests. Tropical rainforests hold about 50% of earth's species of animal. When we bum forests, we Kill the animals too.
The solutions to problems such as deforestation must be found urgently. And. if deforestation continues, in just 100 years there will be no more rainforests left.

The great Inventor
Thomas Alva Edison was probably the greatest inventor. His first job was selling newspapers on trains, and later, at the age of 16, he got a job working in a telegraph office. Not all of Edison's inventions were successful. In fact his first one was a failure. Many that followed, however, were fright successes and Edison became famous. Most people regard him as a genius. Edison worked hard all his life, often working all night in his laboratory, and would not come home for days sometimes. When asked what makes a genius he said: "Genius is 99% perspiration and 1% inspiration." Although most of the inventions which made Edison famous were made in the first half of his life, Edison continued to work and invent till he was over 70, often working 16 hours a day! During his long and productive life, Edison made 1,300 inventions.
One of the most important inventions is the light bulb. Thomas Edison tried two thousand different materials in search of a filament for the light bulb. When none worked satisfactorily, his assistant complained, "All our work is in vain. We have learned nothing." Edison replied very confidently, "Oh, we have come a long way and we have learned a lot. We know that there are two thousand elements which we cannot use to make a good light bulb. Edison died October 18, 1931, at the age of 84.
