Farming and agriculture have been instrumental to our lives for a very long time. In fact, it dates back several thousand years and is still incredibly important to this day. Farming used to only be done on a large scale, but this is no longer the case. Plenty of people operate their own small gardens or farms on their property or at community gardens.
In their search for a highly efficient renewable source of energy, scientists are trying all that they can. Apart from going for solar and wind energy, they are also exploring many other alternatives as well. While doing this, they have provided us with many alternatives. From tidal energy, geothermal energy to utilizing even Hydrogen Fuel Cells, they have found many viable alternatives. However, now they are going even further with their knowledge. Scientists have even found a way for generating electricity from sound. Here’s everything you might want to know about it.
Let’s face it. Fossil fuels are killing the planet. Not only has the world’s population grown exponentially, but so has the world’s use of these non-renewable energy sources. The exhaust from the burning of coal and petroleum has put hundreds of tons of pollutants into the air. The chemicals we are pumping into the atmosphere are heating up the planet, melting glaciers and the ice caps, creating stronger, more devastating storms, and making it harder for animal life to survive.
The expression ‘it’s a small world’ has never been more apt. We live in an age when it is impossible to be unaware of global environmental problems. Pollution and climate change affect us all and millions of people are now asking themselves what changes they can make to their lifestyle to try and help combat the destruction of the environment. We are all beginning to understand the environmental cost of the fossil fuels that comprise our three main energy sources, oil, coal and natural gas.
