here is a report about deforestation

Deforestation

Wood is a strong material from trees, so in order to get it we must chop down trees. But have chop down too many trees? because i am going to tell you the effects of deforestation.

There are several causes and effects of deforestation. The first is erosion, trees stop soil by river banks from tumbling down into the river. But when trees get chopped down, all that soil come tumbling down into the river causing erosion, and also it will poison the fish. Which means fishermans won’t be able to feed themselves.

The second cause and effect is forest fires, the forest is home to many plants, animal and insects. And when a forest fire will kill all those animals and insects. And plus forest fires can be a harm to nearby houses.

My last cause and effect climate change. Forest cool down naturally,and also goes through a course called ‘Photosynthesis’ where Co2 gets absorbed and O2 comes out. So chopped trees will cause Co2 levels to rise. And also forest fires will make temperatures rise.

History Of Cellphones

Cellphones are portable,smart,easy to use and tough.But do you know how all this started?Well I am about to tell you.

The idea of phones first started in 1928.And since then radio technology has started to evolve.Phones were used in war.And on 1973 the first cellphone was made.As technology evolved,entertainment was installed like music,games and cameras.

In 1910 Lars Ericssion installed a phone in his car, but this was not a radio phone.He would travel the country and use a accessible telephone line.Using a long pair of electrical wires,he could connect up to the national telephone network.

Also in 1946 Soviet engineers G.Sharpio and I.Zaharchecko succesfully tested their version of radio mobile,mounted inside a car.It could connect up to a network from a range up to 20 kilometers.

In the 1990’s the ‘second generation‘ was introduced.Known as the 2g network.The 2g network worked by having a digital circuit that switched transmissions,and it was also the introduction to advance and fast phone-to-network signaling.

Not long after the 2g network,people started to work on the ‘third generation‘ also known 3g network.After awhile in 2007, over 295 million people subscribed on 3g network worldwide.3g telecom services has earned over 120 billion dollars.And so it was clear that the 3g network is a profitable service.
