We use huge amounts of natural resources and produce too much rubbish. Pollution is changing the Earth's climate and our planet is getting hotter. The big question is: Will things ever change for the better?.
There are some scientists who are optimistic. They believe that with the help of science and strict laws today's enviromental problems will disappear in the future. Other scientists are pessimistic. They believe that enviromental problems are getting worse and soon it will be too late to save the environment. Let's see what predictions the pessimistic and the optimistic scientists have made about life on Earth in the year 2100.
PESSIMISTIC:
- The Earth's population will probably be 22.2 billion.
- The Earth's temperature will be 1.4 to 5.8 degrees Celsius higher than it is today.
- The ice at the North and South Pole will melt and the sea level will rise by 9 to 88 cm. Cities at or below sea level will sink.
- Half of the Earth's plants and animals will disappear along with the tropical rain forests
- People won't be able to survive on Earth, so they will have to find a new planet to live on.
- The law will oblige families to have no more than one child, and this will reduce the Earth's population to two billion
- People will use enviromentally-friendly energy sources like the sun and the wind, which do not pollute the air, so the Earth's temperature will not increase
- Strict laws will protect animal and plant species from extinction.
- A population of two billion people will need fewer natural resources, so there will be enough food, water, etc. for every one.

What do you think about this? Write a paragraph about two situations. What's your positions?
i think that the problem is obout us, because we are who destroy everything in our way. this problem is for all of us, the human beings. as we lately, in 2100 there will be no life, and if be life, this will be very complicated and difficult.
I don't get to any side, but obviously i want will be life to enjoy all the progress they have, and that life will be confortable.
Thanks, Yurany... Please, Could you tell me, which school you belong to?
Yurany Protecting the environment is a serious matter.. But we can help the environment:
"Be green, get active and have fun, too"
Clean up, collect rubbish and take it for recyclin.
I'm pesimistic because the law has tried every means to reduce the birth rate and neglect of people have not allowed it, also because our impact have been severe and i'm not sure earth will recover that easily even with the best technology, also because every alternative source or new technology have also an impact on the earth's resources.

I'm optimistic because I'm sure that our responsible and uncorruptible governments shall always, thinking in our well-being and happinnes, do everything that is in their power to save our planet. Regarding the part on alternate energy sources, I'm certain that in a few weeks or months, someone will come up with a way of turning manure into an energy source.
I am pessimistic because I think if the government forced the families, families would make him evil and not really do anything.
if so we all documentaries we see on tv in a desert with temperatures higher than will 5.2 celsius be able to survive.
the poles no longer exist and the animals that live in them will die as there are many other sides of the planet's life, not return

Optimistic! I believe in the possibility of changing the planet situation and be able to let the future generations see and enjoy all the things we have right know.
