The document discusses the causes of climate change, including both natural factors like continental drift and volcanic activity, as well as human factors like burning fossil fuels, industrial emissions, land use changes, deforestation, and animal agriculture. It states that modern research suggests human activities have rapidly increased global temperatures in recent decades. To address climate change, the document recommends that humans minimize their environmental impact by reducing waste, reusing materials, and recycling.

1. Climate Change

2. Causes of climate change
1.Continental Drift
2.Solar radiation
3. Changes in Earth's orbit
4. Volcanic activity
5. Changes in ocean currents
6. Human factors

3. Human factors
Human activities affect the
environment ， modern scientific research tend
to think that in the most recent decades, human
activities resulting in global temperatures rose
rapidly.
Humans should minimize the impact of climate
activities and try to eliminate the evil
consequences.

4. The biggest factors of the human
impact on climate
1.The burning of fossil fuels and
manufacturing cement
2.Emissions of CO2 and particulates
3.Land use
4.Ozone Depleting
5.Animal husbandry and agricultural
activities
6. Deforestation

5. Reuse--Water
Collect water when we are take a shower
or wash vegetable and rice , then we can
use them to do something ,like : flush the
toilet 、 water the flowers 、 mop the
floor.......

6. Reuse--Paper
We use the wastepaper to make the
leaflets or calculation paper ……..

7. As long as they abide by the following steps
we believe that the Earth will gradually
recovered
Reduce Reuse Recycle
