Global Warming is threatening to bring animals to extinction, cause stronger storms, and bring rising sea levels. This could wreak havoc around the world, disrupting food chains and destroying property. Why is global warming happening? It is because humans have been using too many fossil fuels, which burn and create greenhouse gases, which eventually warms up Earth. To reduce our reliance on fossil fuel, we can use nuclear power or renewable power to create electricity. Deciding between nuclear and renewable is a tough decision, but we should use renewable energy because it will never run out (unlike nuclear), is safer to operate, and will emit less emissions.
