Final answer:
Deforestation and the burning of fossil fuels have significantly impacted the environment by increasing carbon dioxide levels and enhancing the natural greenhouse effect, leading to global warming and environmental changes. Strategies like increasing renewable energy and preserving habitats are crucial in mitigating these impacts.
Step-by-step explanation:
Human actions that have significantly affected the environment include deforestation and the burning of fossil fuels, which release high amounts of carbon dioxide into the atmosphere. Deforestation leads to the destruction of natural habitats and increases the amount of carbon dioxide in the atmosphere due to the reduction of trees that absorb CO2. In contrast, increased use of renewable energy and the preservation of natural habitats, as well as the reduction of carbon emissions, are strategies aimed at mitigating human impact on global climate change.
Global climate change is driven by human enhancement of the natural greenhouse effect through the emission of greenhouse gases like carbon dioxide, methane, and nitrous oxide. The burning of coal, oil, and gas since the Industrial Revolution has significantly altered Earth's atmosphere, leading to global warming and a multitude of related environmental changes such as rising sea levels, extreme weather patterns, and loss of biodiversity.
As populations grow and development expands, natural environments are increasingly endangered. The crucial step to address climate change is to reduce greenhouse gas emissions, such as CO2 released from burning fossil fuels, which is greatly contributing to rapid changes in our climate.
