Answer 2

There are thousands of endangered plant and animal species in the world. Global warming is caused by a phenomenon known as the greenhouse effect. The three forms of fossil fuel are oil, natural gas, and coal. Greenhouse gases trap heat in the atmosphere, which makes the Earth warmer. The Antarctic ozone hole was discovered in 1985. Each molecule of carbon dioxide consists of one atom of carbon and two atoms of oxygen. Switching to energy-saving light bulbs is the easiest way to start saving energy. When we burn fossil fuels, this releases all sorts of gases into the air, ultimately causing air issues such as smog. Climate change is one of the biggest threats we face today. We cannot see or feel ultraviolet radiation, but our skin responds to it by turning darker.
