The environment is in trouble. Since the early 20th century, the average world temperature has risen by about 0.8 degree. One of the biggest causes of global warming is high-energy use. Modern life depends on technology and a lot of energy is needed to light and heat buildings, power vehicles or simply operate our computers and cell phones. When fossil fuels like coal and oil are burned to produce energy they create greenhouse gases. These are gases, which stay in the Earth’s atmosphere and make the world hotter. Waste is also harming the planet. It pollutes the environment and we’re running out of places to put it.
