I'm concerned with the fact that so many animals are getting on the extinct list! We are destroying their habitats. We need to do something to help the animals!  :(

I'm most concerned with how many animals and how much land is being destroyed. Sooner or later there will be nothing.

I am by far most concerned with the habitats being destroyed. I would like us to all help preserve biodiversity and habitats.

I think anti-hunters are a threat.  If it wasn't for us hunters controlling the population, then these anti-hunters would be complaining about animals coming into their towns and cities because the population would be out of control.

I am by far most concerned with the habitats being destroyed. I would like us to all help preserve biodiversity and habitats.

I am especially concerned with the destruction of habitats because of us humans. Many our financial and environmental crisis all ends up because of us taking up so many places where animals can be currently living there and enjoying their lives innocently! Our human destruction also affects us! We inhale the polluted air, and then our lungs get black as if we were smoking! Many places both we as humans and animals can all live in peace and harmony together. Where the humans take up the environments needed for animals to survive, we are taking over them selfishly. Many animals are becoming extinct soon enough! If we do not stop this march of animal and habitat destruction, at one point we will all hit rock bottom with no animals, no habitats! And we never want that to happen! Do we?

I agree. Many people are cutting down trees. If people keep on doing this we will have less oxygen each and every day.

I am most concerned with the destruction of the animal habitats. If all of the habitats get destroyed the animals will die and there will be no more at all!

Dear Veronica, I agree. I am also concerned about the destruction of habitats. I live in front of the ocean and it feels like a dream. But I feel sad because I know that we, humans, are harming the ocean. And I can’t tell you how much sadness I feel when I see people throwing papers at the ocean. Once, I even saw an old wood table thrown in the ocean, and it makes you feel sad. Yours truly, Belen

I am most concerned about littering. When people in the morning, afternoon or at night the animals or plants think it's food and they eat and they eventually die and people think it's funny but it's not. So if we educate people more then we could save the world and not endanger the animals.

The threat that I am mostly concerned with is the pollution and cutting down trees because pollution is killing much wildlife in this world that we may get a chance to see but maybe not the generations down and we still have much to learn from wildlife. Another horrible thing is cutting down trees is also leading to killing wildlife like in the rainforest where most of the animals there may not adapt to any other biome and still we need a cure for many things like cancer which may be in the rainforest. So please protect this world because it's our only place we can live on for now.

I am concerned with humans destroying habitats most because I see the ocean every day, and to imagine if it would all be ruined is just really terrible. I hope we as humans get everything together soon or else habitats will be destroyed.

I am most concerned with the destruction of habitats.  I live near the Atlantic Ocean and am constantly in the water.  It saddens me how our actions negatively affect all the marine life in there.  I believe if people were more educated, they would care more.

I'm most concerned with the fact that if global warming continues not only will all islands sink (because of the sun melting glaciers) but all the fresh water that we are getting from glaciers will run out! I hope people will realize this and start getting electric cars!!! I also hope that word of the new car that runs on air will get out in time!!!!

I am most concerned with the threat humans are making by destroying organisms habitats. If we keep doing this then many animals will become extinct and extintion is forever!!
