We Can Make A Difference

Climate change may be a big problem, but there are many little things we can do to make a difference. If we try, most of us can do our part to reduce the amount of greenhouse gases that we put into the atmosphere. Many greenhouse gases come from things we do every day. As we have learned, these greenhouse gases trap energy in the atmosphere and make the Earth warmer.

Driving a car or using electricity is not wrong. We just have to be smart about it.Some people use less energy by carpooling. For example, four people can ride together in one car instead of driving four cars to work. Here are some additional ways you can help make the planet a better place.

Save Electricity

Whenever we use electricity, we help put greenhouse gases into the air. By turning off lights, the television, and the computer when you are through with them, you can help a lot.

Bike, Bus, and Walk

You can save energy by sometimes taking the bus, riding a bike, or walking.

Talk to Your Family and Friends

Talk with your family and friends about climate change. Let them know what you've learned.

Plant Trees

Planting trees is fun and a great way to reduce greenhouse gases. Trees absorb carbon dioxide, a greenhouse gas, from the air.

Recycle

Recycle cans, bottles, plastic bags, and newspapers. When you recycle, you send less trash to the landfill and you help save natural resources, like trees, oil, and elements such as aluminum.

When You Buy, Buy Cool Stuff

There are lots of ways we can improve the environment. One of the ways to reduce the amount of greenhouse gases that we put into the air is to buy products that don't use as much energy. By conserving energy, we help reduce climate change and make the Earth a better place. Some products – like certain cars and stereos – are made specially to save energy.

With the development of economy, more and more high buildings are being built in large and medium-sized cities across the country. In urbanization, however, one thing should not be neglected---environmental protection. It is unscientific to judge a city’s modernization level by the number of high buildings. Recently, a new concept “environmental image” has come into being and become an important criterion with which to evaluate a city.

The concept stresses that a modern city must have efficient environmental promotion. It must have a proper proportion of green land, clean water and fresh air. To add more greenery to a city, I would like to make the following proposals:

1. We should popularize “vertical greenery” technique, that is, to plant more green-leaved plants like Boston ivy in densely-located buildings. The roof space of buildings should be used fully to plant flowers, fruits and grasses.

2. Certain room should be reserved for green belts, green patches in the building of new residential districts and the reconstruction of urban areas.

3. Measures should be taken to strengthen people’s awareness of greenery. People should, for example, be encouraged to plant “wedding trees” and “birthday trees”.

Many people are wondering what the future city will look like. If I were to look into my crystal ball, what I would see is that future cities will be clean, green and full of optimism and hope.

The city of the future will be cleaner and greener because of solar and hydrogen energy. Elevated hydrogen trains (Hyrail) will be powered by solar energy that electrolyzes water for fuel cells. This electricity will power MagLev Hyrail trains.

Also running through future cities will be, at ground level, hydrogen fuel cell trains (or Hydrail). While Hyrail will most typically be passenger trains, hauling people around the future cities, Hydrail will be using the power of hydrogen fuel cells to haul cargo inside and outside of town.

The future cities of America and elsewhere will also be heavily equipped with solar panels. There will be photovoltaic panels on the rooftops on almost every building and the windows of each building will double as solar panels as well.

And, of course what would a future city be without a future car for every driver? These future cars will run on hydrogen, electricity, biofuels and even air. There may even be a few future flying cars that sail above traffic during rush hour. Thing Jetson or Flux Capacitor, then think again. Prototypes are here now.

Einstein Cities ...

In the cities of the future, every building will have smart technology. The smart technology will distribute and conserve energy through the building where it is needed most. Also, many buildings using solar energy will produce more electricity than they consume. They will be tied into the smart grid, selling power back and the smart grid will redistribute the energy in sections of the state and country where it is needed most.

The future city will also be inhabited with huge balloons filled with algae the produce hydrogen. This hydrogen will then either be run through stationary fuel cells to provide energy or be used as fuel for cars.

City life in the future will be a bit different than it is today. Future phones and laptops will have merged into small hybrids with WiFi everywhere and VoIP the standard for carrying voice and video data.金大话英语培训网

Life in the future city will have people even more plugged in than they are today. Virtual conferencing using virtual reality will be standard.

Future robots will have taken over the many tasks. The Honda ASIMO robot will be in a Tech Museum right downtown. Other kinds of robots will inhabit thefuture home.

People will only travel for vacation as the need to travel for business will be eliminated with the virtual business world. And for people who do want to go on vacation will do so either on supersonic jets or Maglev bullet trains.

The typical future city will also be filled with people using jetpacks instead of driving their own vehicles or in addition to their vehicles. Fuel grade hydrogen peroxide will power these jetpacks that only emit water vapor and will be able to travel for miles before refueling.

Nano Tech Cities ...

This vision of what the future cities will look like is all based upon emerging technology that is available now. This emerging technology of course has to be refined, downsized in many cases and of production quality. Look for nanotechnology to have taken over in many fields.

The future city will be a bright, hopeful place filled with green energy, interconnectivity and applied virtual reality.
