We can do many ways to improve the environment. First, we need to save energy by turning off the lights or electric devices when you are not using them. Second, to keep the environment clean, we should reduce the amount of waste, throw household garbage properly to its place. To do this, we can recycle more rubbish such as glass, paper, plastic and so on. Moreover, giving old clothes to charity instead of throw them away is also a good way to protect the environment. Next, we will organise some campaigns to raise people’s knowledge about the importance of the environment like picking up rubbish in the parks, collecting litter on the rivers…Last but not least, we ought to plant trees to make the atmosphere fresher. For example, we can grow flowers or our own vegetables. To sum up, we can do a lot of things to improve the environment. When we improve the environment, we are improving our lives and our future as well.

- A: Do you find that it's hotter these days?
- B: Yes, it's hot because it's the beginning of summer.
- A: No, I mean this year is hotter than last year.
- B: Maybe you're right because the earth's temperature increases year by year. This won't stop until people can reduce all types of pollution which causes the global warming.
- A: I think reducing pollution is not easy at all. Human life requires the producing of goods, so natural resources are exploited to make products. Then waste will still be created and people will pollute the environment again and again.
- B: Well, it's not easy, but it's possible. Many countries are trying to recycle things and look for new sources of energy. They also issue laws and have lots of programs to protect the environment.
- A: How can recycling things and finding new sources of energy help to reduce pollution?
- B: If people recycle more things, they will use fewer natural resources and there will be less waste. New sources of energy can replace the using of fossil fuels which results in most types of pollution.
- A: That seems the logical things. I hope it will be better soon because we can't live healthily in this hot weather and the polluted environment. I can't imagine how life on earth will look like in the next 100 years.
- B: Yeah, it's hard to imagine.

Before:

Build an emergency kit and make a family communications plan.

Avoid building in a floodplain unless you elevate and reinforce your home.

Elevate the furnace, water heater and electric panel in your home if you live in an area that has a high flood risk.

Consider installing "check valves" to prevent flood water from backing up into the drains of your home.

If feasible, construct barriers to stop floodwater from entering the building and seal walls in basements with waterproofing compounds.

During:

Listen to the radio or television for information.

Be aware that flash flooding can occur. If there is any possibility of a flash flood, move immediately to higher ground. Do not wait for instructions to move.

Be aware of stream, drainage channels, canyons and other areas known to flood suddenly. Flash floods can occur in these areas with or without typical warnings such as rain clouds or heavy rain.

After:

Avoid moving water.

Stay away from damaged areas unless your assistance has been specifically requested by police, fire, or relief organization.

Emergency workers will be assisting people in flooded areas. You can help them by staying off the roads and out of the way.

Play it safe. Additional flooding or flash floods can occur. Listen for local warnings and information. If your car stalls in rapidly rising waters, get out immediately and climb to higher ground.

Return home only when authorities indicate it is safe.
