A short view to Global Warming
With the rapid increasing of the technology and industry people are using lots of new tools that are run by the petrol and other harmful materials. Especially after the industrial revolution the world start to be bad place in order to live and day by day our environment is becoming a miserable and after some time in future it will be impossible for people in the our planet because of the pollution. 
On this point when we look at the general point each year hundreds of animals are dying because of the global warming and again similarly to this situation millions of plants are dying because of the global warming and poisonous gases and then as a result of the dying of the species the balance in our planet is going to breaking down and after some time this situation will be worse for the people and the losing of the species will be reason for the dying of the people. On the other hand the gases that are harmful always damaging the ozone layer and after some time if the ozone layer is penetrated by these gases that will be destroying for the whole world. On this point people are preparing lots of things in order to protect the planet from these harmful effects of the industrial revolution and the carelessness of the people about the planet. And with the rapid development of the technology people are trying to find alternative things in order to protect the planet. It can be said that there are lots of alternative sources in the world today. In order to get energy people are trying to find lots of ways. For instance; they are getting help from the nature and again by this way they are not only getting help from the nature and but also they are protecting the nature in this way. When we look at the our modern day there are lots of alternative energy sources, now let’s look at these alternative energy sources.
The Number of Alternative Energy sources
When we look at the alternative energy sources in the world we can see that there are lots of them and again with the rapid development of the technology and the power of human mind in future the number of these alternative energy sources will be increased too much extend. Today we have 6 alternative energy sources and they are called not only as alternative energy sources but also renewable energy sources. These alternative energy sources are solar energy, wind energy, geothermal energy, wave energy, flow energy and lastly hydrogen energy. From the long years people have been using these types of renewable energies and in the future again people will be used these alternative energy sources. They have lots of benefits for the earth for example they are easy to get, they are cheap and maybe the most important thing is that they are renewable.
