Droughts are the biggest threat to biodiversity. They are killing many ecosystems that need water to survive.

I think the biggest threat to biodiversity is pollution, because pollution is very harmful to animals and people. It can get in our water, and if we drink that water we will possibly get sick. Pollution gets in our soil and then our crops cannot grow. Pollution can kill us.

Pollution! It's deadly to us humans, animals, and even nature!!

I think construction is the biggest threat to biodiversity.  People are driving wildlife right out of their habitat, then they complain about the animals threatening their towns. People need to think we were the ones that built into their habitat. I have to agree with you.

I also think that the biggest threat to biodiversity are oil spills like the one that happened in the Gulf Of Mexico.

I think the biggest threat to biodiversity would be polluting. If we pollute too much it would harm the animals, plants, and us. 

We should all pick up trash so that biodiversity won't be under threat anymore. Instead of throwing stuff on the ground you could pick it up and throw it away.

There are many threats to biodiversity, these include: deforestation, pollution, and landfilling. But the one that I think is doing the biggest damage is pollution. Pollution is causing hot air to go up in the atmosphere and hit the ozone layer. The more this air hits the ozone layer the more it breaks apart and if the ozone layer does break then there will be incredible heat causing glaciers to melt, more animals/people getting skin cancer, and islands sinking since there is too much water in the area after glaciers melt. But that's not all. If glaciers melt then the water level will rise up flooding lakes and rivers with salt water. So as people run out of water supply people will be counting on getting their water from the freshwater glaciers. Just one problem, all the glaciers have been melted. This can cause millions of species of biodiversity to die. The only species that will survive are those in the desert. (since they can live for years without water and will drink from rainfall) So people need to: stop polluting, get electric cars, not burn things so often, reuse, recycle, and compost. We don't want biodiversity ruined because of us.

I think the biggest threat to biodiversity are oil spills because they pollute the ocean. This effects the fish and causes them to die and the sea creatures to die and the humans cannot swim in the ocean. It not very exciting news but if we could educate people correctly, we could help the ocean stay cleaner and let the sea creatures live!!

I live in Key Biscayne Fl, and I think the biggest threat to Biodiversity is we as humans destroying forests, coral reefs and many more.  The 3 main things that humans do is:  factories, houses and littering. This makes animals become extinct.

I agree that humans are the biggest threat to biodiversity.  However, if we could educate people and make them aware of the damage they are causing, that could change.

I think the greatest threat is forest destruction. These are some reasons to support my answer.

I think the biggest threat to biodiversity would be oil spills. When an oil spill occurs it leaks into the ocean and onto the shore. When it leaks in the ocean it kills many homes for fish and for other aquatic life.
