 Global warming is harming our environment and we as people need to step up to help stop this. So how does global warming effect our environment? With this speech I’m going to cover how it affects us, the environment, our animals and what we can do to prevent this for a better future. My first main point what causes all of this? Greenhouse gases are trapping energy that is warming Earth's climate. The Earth is wrapped in a blanket of air called the atmosphere, which is made up of several layers of gases. The sun is much hotter than the Earth and it gives off rays of heat that travel through the atmosphere and reaches the Earth. The rays of the sun warm the Earth, and heat from the Earth then travels back into the atmosphere. The gases in the atmosphere stop some of the heat from escaping into space. A lot of scientists agree that people’s activities are making the natural greenhouse effect stronger. If we carry on polluting the atmosphere with greenhouse gases, it will have very dangerous effects on the Earth. Also this causes severe weathers if ice is melting it cause sea levels to rise which can result in floods. That will destroy businesses,homes,schools etc. Food is also a problem because certain crops need certain conditions in order the grow properly. As the climate warms, the air holds more moisture and rainstorms become more intense, damaging crops. This will cause food prices to go up ,overall precipitation patterns are also changing, bringing droughts to some areas of the world and floods to others. My second point is that wild life is in threat , with climate change it causes animals to mirgrate other places in order to meet their living standards. For example polar bears live in cold conditions they have needs if the ice melts it can cause problems like Reduced access to food, Drop in body condition, Lower cub survival rates, Increase in drowning, Increase in cannibalism, and their population will decrease.
