Scientists are thinking of ways to lower this risk, such as replacing coal and oil with forms of renewable energy .
But they are also preparing for the worst: what can we do if the terrifying scenes in films such as The Day After Tomorrow happen in real life

One option is to explore other planet to see if we could live on them. The most likely choice is Mars, which...

Why is Mars our Plan B
Today our interest in Martian exploration is greater than ever before.
the Mars Desert Research Station
The Mars Village
Films such as The Martian enjoy worldwide popularity
More governments and organisations are making efforts to educate the public on the Red Planet
Since the 1960s, we have been sending unmanned spacecraft to Mars. Our probes have orbited the planet, sending back valuable data and stunning images.
Our robots have explored the Martian surface, testing the soil and searching for resources, water and signs of life.
Encouraged by discoveries over the years, space agencies of various countries are planning manned missions to Mars that could take place within the next 25 years.
How do human beings explore the Mars
solar radiation
1 Sending people there will require all the
skill, courage and intelligence of the human race.
2 It would take months to reach Mars,
travelling through dangerous solar radiation.
(The Moon can be reached within days).
3 Even if the first settlers do reach Mars safely, they may not be able to return to Earth-ever.
4 Staying alive will be a daily challenge, but not impossible.
What are the challenges of moving to Mars
What is the Biosphere 2 experiment
As early as 1980s, scientists were building Biosphere 2 in the Arizona desert. It consisted of a closed space in which people, animals and plants could live together. The “closed “ concept meant that the space was designed to function with its own oxygen, food and water, needing nothing from the outside world.
What did the Biosphere 2 experiment achieve
Although the two-year experiment was not a success. It did provide us with a better understanding of how humans might be able to live on another planet. More recently, scientists have succeeded in growing a variety of plants in an environment similar to that on Mars, which definitely is a big step forward.
For now, human settlement of Mars is still decades away. In the meantime, scientific research shows that the planet Earth is getting warmer. This change is being caused by human activity and is having a terrible effect on the biosphere. Until we are finally able to live on another planet, we need to take much better care of our own. Right now, it’s the only one we have!
What should human beings do in the near future
Humans have yet not visited Mars.
People want to go to Mars on holiday.
There are plants growing on Mars.
The greatest to life on Earth used to be nuclear missiles.
One day, humans will have to go and live on another planet.
Our Plan A includes developing renewable energy resources.
The Biosphere 2 experiment ended in failure.
Choose the statements that can be inferred from the passage.
Sometimes, we need to form opinions and draw conclusions that are not directly stated within the given information. For example, from the sentence “While the Moon can be reached within days, it would take months to reach Mars, travelling through dangerous solar radiation”, we can infer that the Moon is less exposed to dangerous radiation than Mars. Headings and pictures can also help us make educated guesses about a text.
Learning to learn
1. Would you like to be one of the first people to live on Mars Why or why not
2. Which is better, to live on Mars or to solve Earth's problems Why
No. It is hard to say if the conditions on Mars are safe and proper for human beings to live on it.
I think that it is better to try to solve Earth's prblems. On the one hand, Earth is the place where life began, where life has lived for billions of years. On the other hand, it is easier and safer for us to protect and save our planet than to move to another distant planet.
