Solution 1
For individuals:
1) Individuals can reduce waste by choosing reusable products instead of disposables.
Expected result: By recycling, you can save the resources.
2) You can reduce the use of electricity, water and gas, like taking public transportation instead of private cars.
Expected result: By reducing the use of electricity, water and gas, you can save energy and reduce greenhouse gas emission.
Solution 2
If we all make efforts to reduce greenhouse gas Conclusion: emission, global warming will be slowed down
and the environment will be more pleasant.
