1. Climate change is caused by human activity, such as the burning of fossil fuels and deforestation. To address climate change, we need to reduce our reliance on these activities and transition to renewable sources of energy, like solar and wind power. This can help reduce greenhouse gas emissions and slow down global warming. Additionally, we should also focus on reforestation efforts to absorb carbon dioxide from the atmosphere and restore ecosystems. Finally, we must work together globally to implement policies and technologies that promote sustainability and reduce our impact on the planet.

2. It depends on how much effort we put into solving the problem. If everyone works together and makes significant changes, there is still hope for reducing the effects of climate change and mitigating its worst impacts. However, the longer we wait and the more damage we cause, the harder it becomes to reverse course. Time is running out, so action needs to happen quickly.
