Global Warming Threats and Solutions According to the National Aeronautics and Space Administration (NASA), global warming is defined as “the increase in Earth’s average surface temperature due to rising levels of greenhouse gases” (Dunbar, “What 's in a Name? Global Warming vs. Climate Change"). Global warming is one of the biggest threats that the world is coping with now. Global warming has major impacts on the environment and it is very destructive to human existence on the planet. As a result of global warming, many disasters such as hurricanes, earthquakes, volcano eruption are likely to occur more in the world. However, there are three ways to decrease the effect of global warming, such as “3R” (Reduce, Reuse, Recycle), using clean

There are many reasons why deforestation is a bad thing for global warming and human’s existence on the planet. First, forest trees, like all green plants, absorb harmful gases such as carbon dioxide and release oxygen during photosynthesis. However, when trees are chopped down and burned, or left to rot, they will release carbon dioxide into the air. A statistic from the Environmental Defense Fund exposes that 32 million acres of rainforests are cut down each year and contributes at least 200 billion tons of carbon dioxide in coming decades. Second, deforestation causes loss of many species as 70 percent of the world’s plants and animals live in the rainforests are losing their habitat. Loss of habitat leads to an extinction. It also has some negative consequences for human as their life rely on the animals and plants in the forests for eating and medicine. Flooding and Erosion are also another effects of deforestation. Non-forested areas are susceptible to flooding because of the absence of the tree roots to anchor the soil. Furthermore, when the soils are more exposed to the sun, they will eventually dry out and cannot planting or farming anymore. Erosion is also a worse thing as it causes contamination into the water supply such as streams, lakes, and other water resources. However, reforestation will recover the wildlife habitats, reduce the accumulation of carbon dioxide in the atmosphere, and restore the ecosystem benefits provided by the forests. Humanity cannot afford to lose more of the world’s rainforests as they are suffering from devastating consequences. Hence, reducing deforestation and increasing reforestation are highly embracing in the
